+   TERMS AND CONDITIONS FOR USE, REPRODUCTION, AND DISTRIBUTION
+   1. Definitions.
+      "License" shall mean the terms and conditions for use, reproduction,
+      and distribution as defined by Sections 1 through 9 of this document.
+      "Licensor" shall mean the copyright owner or entity authorized by
+      the copyright owner that is granting the License.
+      "Legal Entity" shall mean the union of the acting entity and all
+      other entities that control, are controlled by, or are under common
+      control with that entity. For the purposes of this definition,
+      "control" means (i) the power, direct or indirect, to cause the
+      direction or management of such entity, whether by contract or
+      otherwise, or (ii) ownership of fifty percent (50%) or more of the
+      outstanding shares, or (iii) beneficial ownership of such entity.
+      "You" (or "Your") shall mean an individual or Legal Entity
+      exercising permissions granted by this License.
+      "Source" form shall mean the preferred form for making modifications,
+      including but not limited to software source code, documentation
+      source, and configuration files.
+      "Object" form shall mean any form resulting from mechanical
+      transformation or translation of a Source form, including but
+      not limited to compiled object code, generated documentation,
+      and conversions to other media types.
+      "Work" shall mean the work of authorship, whether in Source or
+      Object form, made available under the License, as indicated by a
+      copyright notice that is included in or attached to the work
+      (an example is provided in the Appendix below).
+      "Derivative Works" shall mean any work, whether in Source or Object
+      form, that is based on (or derived from) the Work and for which the
+      editorial revisions, annotations, elaborations, or other modifications
+      represent, as a whole, an original work of authorship. For the purposes
+      of this License, Derivative Works shall not include works that remain
+      separable from, or merely link (or bind by name) to the interfaces of,
+      the Work and Derivative Works thereof.
+      "Contribution" shall mean any work of authorship, including
+      the original version of the Work and any modifications or additions
+      to that Work or Derivative Works thereof, that is intentionally
+      submitted to Licensor for inclusion in the Work by the copyright owner
+      or by an individual or Legal Entity authorized to submit on behalf of
+      the copyright owner. For the purposes of this definition, "submitted"
+      means any form of electronic, verbal, or written communication sent
+      to the Licensor or its representatives, including but not limited to
+      communication on electronic mailing lists, source code control systems,
+      and issue tracking systems that are managed by, or on behalf of, the
+      Licensor for the purpose of discussing and improving the Work, but
+      excluding communication that is conspicuously marked or otherwise
+      designated in writing by the copyright owner as "Not a Contribution."
+      "Contributor" shall mean Licensor and any individual or Legal Entity
+      on behalf of whom a Contribution has been received by Licensor and
+      subsequently incorporated within the Work.
+   2. Grant of Copyright License. Subject to the terms and conditions of
+      this License, each Contributor hereby grants to You a perpetual,
+      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
+      copyright license to reproduce, prepare Derivative Works of,
+      publicly display, publicly perform, sublicense, and distribute the
+      Work and such Derivative Works in Source or Object form.
+   3. Grant of Patent License. Subject to the terms and conditions of
+      this License, each Contributor hereby grants to You a perpetual,
+      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
+      (except as stated in this section) patent license to make, have made,
+      use, offer to sell, sell, import, and otherwise transfer the Work,
+      where such license applies only to those patent claims licensable
+      by such Contributor that are necessarily infringed by their
+      Contribution(s) alone or by combination of their Contribution(s)
+      with the Work to which such Contribution(s) was submitted. If You
+      institute patent litigation against any entity (including a
+      cross-claim or counterclaim in a lawsuit) alleging that the Work
+      or a Contribution incorporated within the Work constitutes direct
+      or contributory patent infringement, then any patent licenses
+      granted to You under this License for that Work shall terminate
+      as of the date such litigation is filed.
+   4. Redistribution. You may reproduce and distribute copies of the
+      Work or Derivative Works thereof in any medium, with or without
+      modifications, and in Source or Object form, provided that You
+      meet the following conditions:
+      (a) You must give any other recipients of the Work or
+          Derivative Works a copy of this License; and
+      (b) You must cause any modified files to carry prominent notices
+          stating that You changed the files; and
+      (c) You must retain, in the Source form of any Derivative Works
+          that You distribute, all copyright, patent, trademark, and
+          attribution notices from the Source form of the Work,
+          excluding those notices that do not pertain to any part of
+          the Derivative Works; and
+      (d) If the Work includes a "NOTICE" text file as part of its
+          distribution, then any Derivative Works that You distribute must
+          include a readable copy of the attribution notices contained
+          within such NOTICE file, excluding those notices that do not
+          pertain to any part of the Derivative Works, in at least one
+          of the following places: within a NOTICE text file distributed
+          as part of the Derivative Works; within the Source form or
+          documentation, if provided along with the Derivative Works; or,
+          within a display generated by the Derivative Works, if and
+          wherever such third-party notices normally appear. The contents
+          of the NOTICE file are for informational purposes only and
+          do not modify the License. You may add Your own attribution
+          notices within Derivative Works that You distribute, alongside
+          or as an addendum to the NOTICE text from the Work, provided
+          that such additional attribution notices cannot be construed
+          as modifying the License.
+      You may add Your own copyright statement to Your modifications and
+      may provide additional or different license terms and conditions
+      for use, reproduction, or distribution of Your modifications, or
+      for any such Derivative Works as a whole, provided Your use,
+      reproduction, and distribution of the Work otherwise complies with
+      the conditions stated in this License.
+   5. Submission of Contributions. Unless You explicitly state otherwise,
+      any Contribution intentionally submitted for inclusion in the Work
+      by You to the Licensor shall be under the terms and conditions of
+      this License, without any additional terms or conditions.
+      Notwithstanding the above, nothing herein shall supersede or modify
+      the terms of any separate license agreement you may have executed
+      with Licensor regarding such Contributions.
+   6. Trademarks. This License does not grant permission to use the trade
+      names, trademarks, service marks, or product names of the Licensor,
+      except as required for reasonable and customary use in describing the
+      origin of the Work and reproducing the content of the NOTICE file.
+   7. Disclaimer of Warranty. Unless required by applicable law or
+      agreed to in writing, Licensor provides the Work (and each
+      Contributor provides its Contributions) on an "AS IS" BASIS,
+      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
+      implied, including, without limitation, any warranties or conditions
+      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
+      PARTICULAR PURPOSE. You are solely responsible for determining the
+      appropriateness of using or redistributing the Work and assume any
+      risks associated with Your exercise of permissions under this License.
+   8. Limitation of Liability. In no event and under no legal theory,
+      whether in tort (including negligence), contract, or otherwise,
+      unless required by applicable law (such as deliberate and grossly
+      negligent acts) or agreed to in writing, shall any Contributor be
+      liable to You for damages, including any direct, indirect, special,
+      incidental, or consequential damages of any character arising as a
+      result of this License or out of the use or inability to use the
+      Work (including but not limited to damages for loss of goodwill,
+      work stoppage, computer failure or malfunction, or any and all
+      other commercial damages or losses), even if such Contributor
+      has been advised of the possibility of such damages.
+   9. Accepting Warranty or Additional Liability. While redistributing
+      the Work or Derivative Works thereof, You may choose to offer,
+      and charge a fee for, acceptance of support, warranty, indemnity,
+      or other liability obligations and/or rights consistent with this
+      License. However, in accepting such obligations, You may act only
+      on Your own behalf and on Your sole responsibility, not on behalf
+      of any other Contributor, and only if You agree to indemnify,
+      defend, and hold each Contributor harmless for any liability
+      incurred by, or claims asserted against, such Contributor by reason
+      of your accepting any such warranty or additional liability.
+   END OF TERMS AND CONDITIONS
+   APPENDIX: How to apply the Apache License to your work.

+  V8
+
+  This license applies to all parts of V8 that are not externally

+  are:
+
+    - PCRE test suite, located in
+      test/mjsunit/third_party/regexp-pcre/regexp-pcre.js.  This is based on the
+      test suite from PCRE-7.3, which is copyrighted by the University
+      of Cambridge and Google, Inc.  The copyright notice and license
+      are embedded in regexp-pcre.js.
+
+    - Layout tests, located in test/mjsunit/third_party/object-keys.  These are
+      based on layout tests from webkit.org which are copyrighted by
+      Apple Computer, Inc. and released under a 3-clause BSD license.
+
+    - Strongtalk assembler, the basis of the files assembler-arm-inl.h,
+      assembler-arm.cc, assembler-arm.h, assembler-ia32-inl.h,
+      assembler-ia32.cc, assembler-ia32.h, assembler-x64-inl.h,
+      assembler-x64.cc, assembler-x64.h, assembler-mips-inl.h,
+      assembler-mips.cc, assembler-mips.h, assembler.cc and assembler.h.
+      This code is copyrighted by Sun Microsystems Inc. and released
+      under a 3-clause BSD license.
+
+    - Valgrind client API header, located at src/third_party/valgrind/valgrind.h
+      This is released under the BSD license.
+
+    - The Wasm C/C++ API headers, located at third_party/wasm-api/wasm.{h,hh}
+      This is released under the Apache license. The API's upstream prototype
+      implementation also formed the basis of V8's implementation in
+      src/wasm/c-api.cc.

+
+  BoringSSL is a fork of OpenSSL. As such, large parts of it fall under OpenSSL
+  licensing. Files that are completely new have a Google copyright and an ISC
+  license. This license is reproduced at the bottom of this file.
+
+  Contributors to BoringSSL are required to follow the CLA rules for Chromium:
+  https://cla.developers.google.com/clas
+
+  Files in third_party/ have their own licenses, as described therein. The MIT
+  license, for third_party/fiat, which, unlike other third_party directories, is
+  compiled into non-test libraries, is included below.
+
+  The OpenSSL toolkit stays under a dual license, i.e. both the conditions of the
+  OpenSSL License and the original SSLeay license apply to the toolkit. See below
+  for the actual license texts. Actually both licenses are BSD-style Open Source
+  licenses. In case of any license issues related to OpenSSL please contact
+  openssl-core@openssl.org.
+
+  The following are Google-internal bug numbers where explicit permission from
+  some authors is recorded for use of their work. (This is purely for our own
+  record keeping.)

+
+  This Academic Free License (the "License") applies to any original work of

+  following notice immediately following the copyright notice for the Original
+  Work:
+
+  Licensed under the Academic Free License version 2.0
+  1) Grant of Copyright License. Licensor hereby grants You a world-wide,
+  royalty-free, non-exclusive, perpetual, sublicenseable license to do the
+  following:
+
+  a) to reproduce the Original Work in copies;
+  b) to prepare derivative works ("Derivative Works") based upon the Original
+     Work;
+  c) to distribute copies of the Original Work and Derivative Works to the
+     public;
+  d) to perform the Original Work publicly; and

+  2) Grant of Patent License. Licensor hereby grants You a world-wide,
+  royalty-free, non-exclusive, perpetual, sublicenseable license, under patent
+  claims owned or controlled by the Licensor that are embodied in the Original
+  Work as furnished by the Licensor, to make, use, sell and offer for sale the
+  Original Work and Derivative Works.
+
+  3) Grant of Source Code License. The term "Source Code" means the preferred
+  form of the Original Work for making modifications to it and all available
+  documentation describing how to modify the Original Work. Licensor hereby
+  agrees to provide a machine-readable copy of the Source Code of the Original
+  Work along with each copy of the Original Work that Licensor distributes.
+  Licensor reserves the right to satisfy this obligation by placing a
+  machine-readable copy of the Source Code in an information repository
+  reasonably calculated to permit inexpensive and convenient access by You for as
+  long as Licensor continues to distribute the Original Work, and by publishing
+  the address of that information repository in a notice immediately following
+  the copyright notice that applies to the Original Work.
+
+  4) Exclusions From License Grant. Neither the names of Licensor, nor the names
+  of any contributors to the Original Work, nor any of their trademarks or
+  service marks, may be used to endorse or promote products derived from this
+  Original Work without express prior written permission of the Licensor. Nothing

+  patents, trade secrets or any other intellectual property of Licensor except as
+  expressly stated herein. No patent license is granted to make, use, sell or
+  offer to sell embodiments of any patent claims other than the licensed claims
+  defined in Section 2. No right is granted to the trademarks of Licensor even if
+  such marks are included in the Original Work. Nothing in this License shall be
+  interpreted to prohibit Licensor from licensing under different terms from this
+  License any Original Work that Licensor otherwise would have a right to
+  license.
+
+  5) This section intentionally omitted.
+
+  6) Attribution Rights. You must retain, in the Source Code of any Derivative
+  Works that You create, all copyright, patent or trademark notices from the
+  Source Code of the Original Work, as well as any notices of licensing and any
+  descriptive text identified therein as an "Attribution Notice." You must cause
+  the Source Code for any Derivative Works that You create to carry a prominent
+  Attribution Notice reasonably calculated to inform recipients that You have
+  modified the Original Work.
+
+  7) Warranty of Provenance and Disclaimer of Warranty. Licensor warrants that
+  the copyright in and to the Original Work and the patent rights granted herein
+  by Licensor are owned by the Licensor or are sublicensed to You under the terms
+  of this License with the permission of the contributor(s) of those copyrights
+  and patent rights. Except as expressly stated in the immediately proceeding
+  sentence, the Original Work is provided under this License on an "AS IS" BASIS
+  and WITHOUT WARRANTY, either express or implied, including, without limitation,
+  the warranties of NON-INFRINGEMENT, MERCHANTABILITY or FITNESS FOR A PARTICULAR
+  PURPOSE. THE ENTIRE RISK AS TO THE QUALITY OF THE ORIGINAL WORK IS WITH YOU.
+  This DISCLAIMER OF WARRANTY constitutes an essential part of this License. No
+  license to Original Work is granted hereunder except under this disclaimer.
+
+  8) Limitation of Liability. Under no circumstances and under no legal theory,
+  whether in tort (including negligence), contract, or otherwise, shall the
+  Licensor be liable to any person for any direct, indirect, special, incidental,
+  or consequential damages of any character arising as a result of this License
+  or the use of the Original Work including, without limitation, damages for loss
+  of goodwill, work stoppage, computer failure or malfunction, or any and all
+  other commercial damages or losses. This limitation of liability shall not
+  apply to liability for death or personal injury resulting from Licensor's
+  negligence to the extent applicable law prohibits such limitation. Some
+  jurisdictions do not allow the exclusion or limitation of incidental or
+  consequential damages, so this exclusion and limitation may not apply to You.
+
+  9) Acceptance and Termination. If You distribute copies of the Original Work or
+  a Derivative Work, You must make a reasonable effort under the circumstances to
+  obtain the express assent of recipients to the terms of this License. Nothing
+  else but this License (or another written agreement between Licensor and You)
+  grants You permission to create Derivative Works based upon the Original Work
+  or to exercise any of the rights granted in Section 1 herein, and any attempt
+  to do so except under the terms of this License (or another written agreement
+  between Licensor and You) is expressly prohibited by U.S. copyright law, the
+  equivalent laws of other countries, and by international treaty. Therefore, by
+  exercising any of the rights granted to You in Section 1 herein, You indicate
+  Your acceptance of this License and all of its terms and conditions.
+
+  10) Termination for Patent Action. This License shall terminate automatically
+  and You may no longer exercise any of the rights granted to You by this License
+  as of the date You commence an action, including a cross-claim or counterclaim,
+  for patent infringement (i) against Licensor with respect to a patent
+  applicable to software or (ii) against any entity with respect to a patent
+  applicable to the Original Work (but excluding combinations of the Original
+  Work with other software or hardware).
+
+  11) Jurisdiction, Venue and Governing Law. Any action or suit relating to this
+  License may be brought only in the courts of a jurisdiction wherein the
+  Licensor resides or in which Licensor conducts its primary business, and under
+  the laws of that jurisdiction excluding its conflict-of-law provisions. The
+  application of the United Nations Convention on Contracts for the International
+  Sale of Goods is expressly excluded. Any use of the Original Work outside the
+  scope of this License or after its termination shall be subject to the
+  requirements and penalties of the U.S. Copyright Act, 17 U.S.C. 101 et seq.,
+  the equivalent laws of other countries, and international treaty. This section
+  shall survive the termination of this License.
+
+  12) Attorneys Fees. In any action to enforce the terms of this License or
+  seeking damages relating thereto, the prevailing party shall be entitled to
+  recover its costs and expenses, including, without limitation, reasonable
+  attorneys' fees and costs incurred in connection with such action, including
+  any appeal of such action. This section shall survive the termination of this
+  License.
+
+  13) Miscellaneous. This License represents the complete agreement concerning
+  the subject matter hereof. If any provision of this License is held to be
+  unenforceable, such provision shall be reformed only to the extent necessary to
+  make it enforceable.
+
+  14) Definition of "You" in This License. "You" throughout this License, whether
+  in upper or lower case, means an individual or a legal entity exercising rights
+  under, and complying with all of the terms of, this License. For legal
+  entities, "You" includes any entity that controls, is controlled by, or is
+  under common control with you. For purposes of this definition, "control" means
+  (i) the power, direct or indirect, to cause the direction or management of such
+  entity, whether by contract or otherwise, or (ii) ownership of fifty percent
+  (50%) or more of the outstanding shares, or (iii) beneficial ownership of such
+  entity.
+
+  15) Right to Use. You may use the Original Work in all ways not otherwise
+  restricted or conditioned by this License or by law, and Licensor promises not
+  to interfere with or be responsible for such uses by You.

+
+      "Object" form shall mean any form resulting from mechanical
+      transformation or translation of a Source form, including but
+      not limited to compiled object code, generated documentation,
+      and conversions to other media types.
+
+      "Work" shall mean the work of authorship, whether in Source or
+      Object form, made available under the License, as indicated by a
+      copyright notice that is included in or attached to the work
+      (an example is provided in the Appendix below).
+
+      "Derivative Works" shall mean any work, whether in Source or Object
+      form, that is based on (or derived from) the Work and for which the
+      editorial revisions, annotations, elaborations, or other modifications
+      represent, as a whole, an original work of authorship. For the purposes
+      of this License, Derivative Works shall not include works that remain
+      separable from, or merely link (or bind by name) to the interfaces of,
+      the Work and Derivative Works thereof.
+
+      "Contribution" shall mean any work of authorship, including
+      the original version of the Work and any modifications or additions

+
+      "Contributor" shall mean Licensor and any individual or Legal Entity
+      on behalf of whom a Contribution has been received by Licensor and
+      subsequently incorporated within the Work.
+
+   2. Grant of Copyright License. Subject to the terms and conditions of
+      this License, each Contributor hereby grants to You a perpetual,
+      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
+      copyright license to reproduce, prepare Derivative Works of,
+      publicly display, publicly perform, sublicense, and distribute the
+      Work and such Derivative Works in Source or Object form.
+
+   3. Grant of Patent License. Subject to the terms and conditions of
+      this License, each Contributor hereby grants to You a perpetual,
+      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
+      (except as stated in this section) patent license to make, have made,
+      use, offer to sell, sell, import, and otherwise transfer the Work,

+      by such Contributor that are necessarily infringed by their
+      Contribution(s) alone or by combination of their Contribution(s)
+      with the Work to which such Contribution(s) was submitted. If You
+      institute patent litigation against any entity (including a
+      cross-claim or counterclaim in a lawsuit) alleging that the Work
+      or a Contribution incorporated within the Work constitutes direct
+      or contributory patent infringement, then any patent licenses
+      granted to You under this License for that Work shall terminate
+      as of the date such litigation is filed.
+
+   4. Redistribution. You may reproduce and distribute copies of the
+      Work or Derivative Works thereof in any medium, with or without
+      modifications, and in Source or Object form, provided that You
+      meet the following conditions:
+
+      (a) You must give any other recipients of the Work or
+          Derivative Works a copy of this License; and
+
+      (b) You must cause any modified files to carry prominent notices
+          stating that You changed the files; and
+
+      (c) You must retain, in the Source form of any Derivative Works
+          that You distribute, all copyright, patent, trademark, and
+          attribution notices from the Source form of the Work,
+          excluding those notices that do not pertain to any part of
+          the Derivative Works; and
+
+      (d) If the Work includes a "NOTICE" text file as part of its
+          distribution, then any Derivative Works that You distribute must
+          include a readable copy of the attribution notices contained
+          within such NOTICE file, excluding those notices that do not
+          pertain to any part of the Derivative Works, in at least one
+          of the following places: within a NOTICE text file distributed
+          as part of the Derivative Works; within the Source form or
+          documentation, if provided along with the Derivative Works; or,
+          within a display generated by the Derivative Works, if and
+          wherever such third-party notices normally appear. The contents
+          of the NOTICE file are for informational purposes only and
+          do not modify the License. You may add Your own attribution
+          notices within Derivative Works that You distribute, alongside
+          or as an addendum to the NOTICE text from the Work, provided
+          that such additional attribution notices cannot be construed
+          as modifying the License.
+
+      You may add Your own copyright statement to Your modifications and
+      may provide additional or different license terms and conditions
+      for use, reproduction, or distribution of Your modifications, or
+      for any such Derivative Works as a whole, provided Your use,
+      reproduction, and distribution of the Work otherwise complies with
+      the conditions stated in this License.
+
+   5. Submission of Contributions. Unless You explicitly state otherwise,
+      any Contribution intentionally submitted for inclusion in the Work
+      by You to the Licensor shall be under the terms and conditions of
+      this License, without any additional terms or conditions.
+      Notwithstanding the above, nothing herein shall supersede or modify
+      the terms of any separate license agreement you may have executed
+      with Licensor regarding such Contributions.
+
+   6. Trademarks. This License does not grant permission to use the trade
+      names, trademarks, service marks, or product names of the Licensor,
+      except as required for reasonable and customary use in describing the
+      origin of the Work and reproducing the content of the NOTICE file.
+
+   7. Disclaimer of Warranty. Unless required by applicable law or
+      agreed to in writing, Licensor provides the Work (and each
+      Contributor provides its Contributions) on an "AS IS" BASIS,
+      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
+      implied, including, without limitation, any warranties or conditions
+      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
+      PARTICULAR PURPOSE. You are solely responsible for determining the
+      appropriateness of using or redistributing the Work and assume any
+      risks associated with Your exercise of permissions under this License.
+
+   8. Limitation of Liability. In no event and under no legal theory,
+      whether in tort (including negligence), contract, or otherwise,
+      unless required by applicable law (such as deliberate and grossly
+      negligent acts) or agreed to in writing, shall any Contributor be
+      liable to You for damages, including any direct, indirect, special,
+      incidental, or consequential damages of any character arising as a
+      result of this License or out of the use or inability to use the
+      Work (including but not limited to damages for loss of goodwill,
+      work stoppage, computer failure or malfunction, or any and all
+      other commercial damages or losses), even if such Contributor
+      has been advised of the possibility of such damages.
+
+   9. Accepting Warranty or Additional Liability. While redistributing
+      the Work or Derivative Works thereof, You may choose to offer,
+      and charge a fee for, acceptance of support, warranty, indemnity,
+      or other liability obligations and/or rights consistent with this
+      License. However, in accepting such obligations, You may act only
+      on Your own behalf and on Your sole responsibility, not on behalf
+      of any other Contributor, and only if You agree to indemnify,
+      defend, and hold each Contributor harmless for any liability
+      incurred by, or claims asserted against, such Contributor by reason
+      of your accepting any such warranty or additional liability.
+
+   END OF TERMS AND CONDITIONS
+
+   APPENDIX: How to apply the Apache License to your work.
+
+      To apply the Apache License to your work, attach the following
+      boilerplate notice, with the fields enclosed by brackets "[]"
+      replaced with your own identifying information. (Don't include
+      the brackets!)  The text should be enclosed in the appropriate
+      comment syntax for the file format. We also recommend that a
+      file or class name and description of purpose be included on the
+      same "printed page" as the copyright notice for easier
+      identification within third-party archives.

+    NSS is available under the Mozilla Public License, version 2, a copy of which
+  is below.
+
+  Note on GPL Compatibility
+  -------------------------
+
+  The MPL 2, section 3.3, permits you to combine NSS with code under the GNU
+  General Public License (GPL) version 2, or any later version of that
+  license, to make a Larger Work, and distribute the result under the GPL.
+  The only condition is that you must also make NSS, and any changes you
+  have made to it, available to recipients under the terms of the MPL 2 also.
+
+  Anyone who receives the combined code from you does not have to continue
+  to dual licence in this way, and may, if they wish, distribute under the
+  terms of either of the two licences - either the MPL alone or the GPL
+  alone. However, we discourage people from distributing copies of NSS under
+  the GPL alone, because it means that any improvements they make cannot be
+  reincorporated into the main version of NSS. There is never a need to do
+  this for license compatibility reasons.
+
+  Note on LGPL Compatibility
+  --------------------------
+
+  The above also applies to combining MPLed code in a single library with
+  code under the GNU Lesser General Public License (LGPL) version 2.1, or
+  any later version of that license. If the LGPLed code and the MPLed code
+  are not in the same library, then the copyleft coverage of the two
+  licences does not overlap, so no issues arise.

+  (a) under intellectual property rights (other than patent or trademark)
+      Licensable by such Contributor to use, reproduce, make available,

+  distributes such Contribution.
+
+  2.3. Limitations on Grant Scope
+
+  The licenses granted in this Section 2 are the only rights granted under
+  this License. No additional rights or licenses will be implied from the
+  distribution or licensing of Covered Software under this License.
+  Notwithstanding Section 2.1(b) above, no patent license is granted by a
+  Contributor:
+
+  (a) for any code that a Contributor has removed from Covered Software;
+      or
+
+  (b) for infringements caused by: (i) Your and any other third party's
+      modifications of Covered Software, or (ii) the combination of its
+      Contributions with other software (except as part of its Contributor
+      Version); or
+
+  (c) under Patent Claims infringed by Covered Software in the absence of
+      its Contributions.
+
+  This License does not grant any rights in the trademarks, service marks,
+  or logos of any Contributor (except as may be necessary to comply with
+  the notice requirements in Section 3.4).
+
+  2.4. Subsequent Licenses
+
+  No Contributor makes additional grants as a result of Your choice to
+  distribute the Covered Software under a subsequent version of this
+  License (see Section 10.2) or under the terms of a Secondary License (if
+  permitted under the terms of Section 3.3).
+
+  2.5. Representation
+
+  Each Contributor represents that the Contributor believes its
+  Contributions are its original creation(s) or it has sufficient rights
+  to grant the rights to its Contributions conveyed by this License.
+
+  2.6. Fair Use
+
+  This License is not intended to limit any rights You have under

+

+
+  3. Responsibilities
+  -------------------
+
+  3.1. Distribution of Source Form
+
+  All distribution of Covered Software in Source Code Form, including any
+  Modifications that You create or to which You contribute, must be under
+  the terms of this License. You must inform recipients that the Source
+  Code Form of the Covered Software is governed by the terms of this
+  License, and how they can obtain a copy of this License. You may not
+  attempt to alter or restrict the recipients' rights in the Source Code
+  Form.
+
+  3.2. Distribution of Executable Form
+
+  If You distribute Covered Software in Executable Form then:
+
+  (a) such Covered Software must also be made available in Source Code
+      Form, as described in Section 3.1, and You must inform recipients of
+      the Executable Form how they can obtain a copy of such Source Code
+      Form by reasonable means in a timely manner, at a charge no more
+      than the cost of distribution to the recipient; and
+
+  (b) You may distribute such Executable Form under the terms of this
+      License, or sublicense it under different terms, provided that the
+      license for the Executable Form does not attempt to limit or alter
+      the recipients' rights in the Source Code Form under this License.
+
+  3.3. Distribution of a Larger Work
+
+  You may create and distribute a Larger Work under terms of Your choice,
+  provided that You also comply with the requirements of this License for
+  the Covered Software. If the Larger Work is a combination of Covered
+  Software with a work governed by one or more Secondary Licenses, and the
+  Covered Software is not Incompatible With Secondary Licenses, this
+  License permits You to additionally distribute such Covered Software
+  under the terms of such Secondary License(s), so that the recipient of
+  the Larger Work may, at their option, further distribute the Covered
+  Software under the terms of either this License or such Secondary
+  License(s).
+
+  3.4. Notices
+
+  You may not remove or alter the substance of any license notices
+  (including copyright notices, patent notices, disclaimers of warranty,
+  or limitations of liability) contained within the Source Code Form of
+  the Covered Software, except that You may alter any license notices to
+  the extent required to remedy known factual inaccuracies.
+
+  3.5. Application of Additional Terms
+
+  You may choose to offer, and to charge a fee for, warranty, support,
+  indemnity or liability obligations to one or more recipients of Covered
+  Software. However, You may do so only on Your own behalf, and not on
+  behalf of any Contributor. You must make it absolutely clear that any
+  such warranty, support, indemnity, or liability obligation is offered by
+  You alone, and You hereby agree to indemnify every Contributor for any
+  liability incurred by such Contributor as a result of warranty, support,
+  indemnity or liability terms You offer. You may include additional
+  disclaimers of warranty and limitations of liability specific to any
+  jurisdiction.
+
+  4. Inability to Comply Due to Statute or Regulation
+  ---------------------------------------------------
+
+  If it is impossible for You to comply with any of the terms of this
+  License with respect to some or all of the Covered Software due to
+  statute, judicial order, or regulation then You must: (a) comply with
+  the terms of this License to the maximum extent possible; and (b)
+  describe the limitations and the code they affect. Such description must
+  be placed in a text file included with all distributions of the Covered
+  Software under this License. Except to the extent prohibited by statute
+  or regulation, such description must be sufficiently detailed for a
+  recipient of ordinary skill to be able to understand it.
+
+  5. Termination
+  --------------
+
+  5.1. The rights granted under this License will terminate automatically
+  if You fail to comply with any of its terms. However, if You become
+  compliant, then the rights granted under this License from a particular
+  Contributor are reinstated (a) provisionally, unless and until such
+  Contributor explicitly and finally terminates Your grants, and (b) on an
+  ongoing basis, if such Contributor fails to notify You of the
+  non-compliance by some reasonable means prior to 60 days after You have
+  come back into compliance. Moreover, Your grants from a particular
+  Contributor are reinstated on an ongoing basis if such Contributor
+  notifies You of the non-compliance by some reasonable means, this is the
+  first time You have received notice of non-compliance with this License
+  from such Contributor, and You become compliant prior to 30 days after
+  Your receipt of the notice.
+
+  5.2. If You initiate litigation against any entity by asserting a patent
+  infringement claim (excluding declaratory judgment actions,
+  counter-claims, and cross-claims) alleging that a Contributor Version
+  directly or indirectly infringes any patent, then the rights granted to
+  You by any and all Contributors for the Covered Software under Section
+  2.1 of this License shall terminate.
+
+  5.3. In the event of termination under Sections 5.1 or 5.2 above, all
+  end user license agreements (excluding distributors and resellers) which
+  have been validly granted by You or Your distributors under this License
+  prior to termination shall survive termination.

+  *  Covered Software is provided under this License on an "as is"       *

+  *  statutory, including, without limitation, warranties that the       *
+  *  Covered Software is free of defects, merchantable, fit for a        *
+  *  particular purpose or non-infringing. The entire risk as to the     *
+  *  quality and performance of the Covered Software is with You.        *
+  *  Should any Covered Software prove defective in any respect, You     *
+  *  (not any Contributor) assume the cost of any necessary servicing,   *
+  *  repair, or correction. This disclaimer of warranty constitutes an   *
+  *  essential part of this License. No use of any Covered Software is   *
+  *  authorized under this License except under this disclaimer.         *
+  *                                                                      *

+  *  --------------------------                                          *

+  *  Under no circumstances and under no legal theory, whether tort      *
+  *  (including negligence), contract, or otherwise, shall any           *
+  *  Contributor, or anyone who distributes Covered Software as          *

+  *  including, without limitation, damages for lost profits, loss of    *

+  *  personal injury resulting from such party's negligence to the       *
+  *  extent applicable law prohibits such limitation. Some               *
+  *  jurisdictions do not allow the exclusion or limitation of           *
+  *  incidental or consequential damages, so this exclusion and          *
+  *  limitation may not apply to You.                                    *
+  *                                                                      *

+
+  8. Litigation
+  -------------
+
+  Any litigation relating to this License may be brought only in the
+  courts of a jurisdiction where the defendant maintains its principal
+  place of business and such litigation shall be governed by laws of that
+  jurisdiction, without reference to its conflict-of-law provisions.
+  Nothing in this Section shall prevent a party's ability to bring
+  cross-claims or counter-claims.
+
+  9. Miscellaneous
+  ----------------
+
+  This License represents the complete agreement concerning the subject
+  matter hereof. If any provision of this License is held to be
+  unenforceable, such provision shall be reformed only to the extent
+  necessary to make it enforceable. Any law or regulation which provides
+  that the language of a contract shall be construed against the drafter
+  shall not be used to construe this License against a Contributor.
+
+  10. Versions of the License
+  ---------------------------
+
+  10.1. New Versions
+
+  Mozilla Foundation is the license steward. Except as provided in Section
+  10.3, no one other than the license steward has the right to modify or

+  distinguishing version number.
+
+  10.2. Effect of New Versions

+  steward.
+
+  10.3. Modified Versions
+
+  If you create software not governed by this License, and you want to
+  create a new license for such software, you may create and use a
+  modified version of this License if you rename the license and remove
+  any references to the name of the license steward (except to note that
+  such modified license differs from this License).

+
+
+                      The FreeType Project LICENSE
+                      ----------------------------
+
+                              2006-Jan-27
+
+                      Copyright 1996-2002, 2006 by
+            David Turner, Robert Wilhelm, and Werner Lemberg
+
+
+
+  Introduction
+  ============
+
+    The FreeType  Project is distributed in  several archive packages;
+    some of them may contain, in addition to the FreeType font engine,
+    various tools and  contributions which rely on, or  relate to, the
+    FreeType Project.
+
+    This  license applies  to all  files found  in such  packages, and
+    which do not  fall under their own explicit  license.  The license
+    affects  thus  the  FreeType   font  engine,  the  test  programs,
+    documentation and makefiles, at the very least.
+
+    This  license   was  inspired  by  the  BSD,   Artistic,  and  IJG
+    (Independent JPEG  Group) licenses, which  all encourage inclusion
+    and  use of  free  software in  commercial  and freeware  products
+    alike.  As a consequence, its main points are that:
+
+      o We don't promise that this software works. However, we will be
+        interested in any kind of bug reports. (`as is' distribution)
+
+      o You can  use this software for whatever you  want, in parts or
+        full form, without having to pay us. (`royalty-free' usage)
+
+      o You may not pretend that  you wrote this software.  If you use
+        it, or  only parts of it,  in a program,  you must acknowledge
+        somewhere  in  your  documentation  that  you  have  used  the
+        FreeType code. (`credits')
+
+    We  specifically  permit  and  encourage  the  inclusion  of  this
+    software, with  or without modifications,  in commercial products.
+    We  disclaim  all warranties  covering  The  FreeType Project  and
+    assume no liability related to The FreeType Project.
+
+
+    Finally,  many  people  asked  us  for  a  preferred  form  for  a
+    credit/disclaimer to use in compliance with this license.  We thus
+    encourage you to use the following text:
+
+     """
+      Portions of this software are copyright © <year> The FreeType
+      Project (www.freetype.org).  All rights reserved.
+     """
+
+    Please replace <year> with the value from the FreeType version you
+    actually use.
+
+
+  Legal Terms
+  ===========
+
+  0. Definitions
+  --------------
+
+    Throughout this license,  the terms `package', `FreeType Project',
+    and  `FreeType  archive' refer  to  the  set  of files  originally
+    distributed  by the  authors  (David Turner,  Robert Wilhelm,  and
+    Werner Lemberg) as the `FreeType Project', be they named as alpha,
+    beta or final release.
+
+    `You' refers to  the licensee, or person using  the project, where
+    `using' is a generic term including compiling the project's source
+    code as  well as linking it  to form a  `program' or `executable'.
+    This  program is  referred to  as  `a program  using the  FreeType
+    engine'.
+
+    This  license applies  to all  files distributed  in  the original
+    FreeType  Project,   including  all  source   code,  binaries  and
+    documentation,  unless  otherwise  stated   in  the  file  in  its
+    original, unmodified form as  distributed in the original archive.
+    If you are  unsure whether or not a particular  file is covered by
+    this license, you must contact us to verify this.
+
+    The FreeType  Project is copyright (C) 1996-2000  by David Turner,
+    Robert Wilhelm, and Werner Lemberg.  All rights reserved except as
+    specified below.
+
+  1. No Warranty
+  --------------
+
+    THE FREETYPE PROJECT  IS PROVIDED `AS IS' WITHOUT  WARRANTY OF ANY
+    KIND, EITHER  EXPRESS OR IMPLIED,  INCLUDING, BUT NOT  LIMITED TO,
+    WARRANTIES  OF  MERCHANTABILITY   AND  FITNESS  FOR  A  PARTICULAR
+    PURPOSE.  IN NO EVENT WILL ANY OF THE AUTHORS OR COPYRIGHT HOLDERS
+    BE LIABLE  FOR ANY DAMAGES CAUSED  BY THE USE OR  THE INABILITY TO
+    USE, OF THE FREETYPE PROJECT.
+
+  2. Redistribution
+  -----------------
+
+    This  license  grants  a  worldwide, royalty-free,  perpetual  and
+    irrevocable right  and license to use,  execute, perform, compile,
+    display,  copy,   create  derivative  works   of,  distribute  and
+    sublicense the  FreeType Project (in  both source and  object code
+    forms)  and  derivative works  thereof  for  any  purpose; and  to
+    authorize others  to exercise  some or all  of the  rights granted
+    herein, subject to the following conditions:
+
+      o Redistribution of  source code  must retain this  license file
+        (`FTL.TXT') unaltered; any  additions, deletions or changes to
+        the original  files must be clearly  indicated in accompanying
+        documentation.   The  copyright   notices  of  the  unaltered,
+        original  files must  be  preserved in  all  copies of  source
+        files.
+
+      o Redistribution in binary form must provide a  disclaimer  that
+        states  that  the software is based in part of the work of the
+        FreeType Team,  in  the  distribution  documentation.  We also
+        encourage you to put an URL to the FreeType web page  in  your
+        documentation, though this isn't mandatory.
+
+    These conditions  apply to any  software derived from or  based on
+    the FreeType Project,  not just the unmodified files.   If you use
+    our work, you  must acknowledge us.  However, no  fee need be paid
+    to us.
+
+  3. Advertising
+  --------------
+
+    Neither the  FreeType authors and  contributors nor you  shall use
+    the name of the  other for commercial, advertising, or promotional
+    purposes without specific prior written permission.
+
+    We suggest,  but do not require, that  you use one or  more of the
+    following phrases to refer  to this software in your documentation
+    or advertising  materials: `FreeType Project',  `FreeType Engine',
+    `FreeType library', or `FreeType Distribution'.
+
+    As  you have  not signed  this license,  you are  not  required to
+    accept  it.   However,  as  the FreeType  Project  is  copyrighted
+    material, only  this license, or  another one contracted  with the
+    authors, grants you  the right to use, distribute,  and modify it.
+    Therefore,  by  using,  distributing,  or modifying  the  FreeType
+    Project, you indicate that you understand and accept all the terms
+    of this license.
+
+  4. Contacts
+  -----------
+
+    There are two mailing lists related to FreeType:
+
+      o freetype@nongnu.org
+
+        Discusses general use and applications of FreeType, as well as
+        future and  wanted additions to the  library and distribution.
+        If  you are looking  for support,  start in  this list  if you
+        haven't found anything to help you in the documentation.
+
+      o freetype-devel@nongnu.org

+  conditions:
+  (1) If any part of the source code for this software is distributed, then this
+  README file must be included, with this copyright and no-warranty notice
+  unaltered; and any additions, deletions, or changes to the original files
+  must be clearly indicated in accompanying documentation.
+  (2) If only executable code is distributed, then the accompanying
+  documentation must state that "this software is based in part on the work of
+  the Independent JPEG Group".
+  (3) Permission for use of this software is granted only if the user accepts
+  full responsibility for any undesirable consequences; the authors accept
+  NO LIABILITY for damages of any kind.
+
+  These conditions apply to any software derived from or based on the IJG code,
+  not just to the unmodified library.  If you use our work, you ought to
+  acknowledge us.
+
+  Permission is NOT granted for the use of any IJG author's name or company name
+  in advertising or publicity relating to this software or products derived from
+  it.  This software may be referred to only as "the Independent JPEG Group's
+  software".

+
+  ansi2knr.c is included in this distribution by permission of L. Peter Deutsch,
+  sole proprietor of its copyright holder, Aladdin Enterprises of Menlo Park, CA.
+  ansi2knr.c is NOT covered by the above copyright and conditions, but instead
+  by the usual distribution terms of the Free Software Foundation; principally,
+  that you must include source code if you redistribute it.  (See the file
+  ansi2knr.c for full details.)  However, since ansi2knr.c is not needed as part
+  of any program generated from the IJG code, this does not limit you more than
+  the foregoing paragraphs do.
+
+  The Unix configuration script "configure" was produced with GNU Autoconf.
+  It is copyright by the Free Software Foundation but is freely distributable.
+  The same holds for its supporting scripts (config.guess, config.sub,
+  ltconfig, ltmain.sh).  Another support script, install-sh, is copyright
+  by M.I.T. but is also freely distributable.
+
+  It appears that the arithmetic coding option of the JPEG spec is covered by
+  patents owned by IBM, AT&T, and Mitsubishi.  Hence arithmetic coding cannot
+  legally be used without obtaining one or more licenses.  For this reason,
+  support for arithmetic coding has been removed from the free JPEG software.
+  (Since arithmetic coding provides only a marginal gain over the unpatented
+  Huffman mode, it is unlikely that very many implementations will support it.)
+  So far as we are aware, there are no patent restrictions on the remaining
+  code.
+
+  The IJG distribution formerly included code to read and write GIF files.
+  To avoid entanglement with the Unisys LZW patent, GIF reading support has
+  been removed altogether, and the GIF writer has been simplified to produce
+  "uncompressed GIFs".  This technique does not use the LZW algorithm; the
+  resulting GIF files are larger than usual, but are readable by all standard
+  GIF decoders.
+
+  We are required to state that
+      "The Graphics Interchange Format(c) is the Copyright property of
+      CompuServe Incorporated.  GIF(sm) is a Service Mark property of
+      CompuServe Incorporated."

+      copyright license to reproduce, prepare Derivative Works of,
+      publicly display, publicly perform, sublicense, and distribute the
+      Work and such Derivative Works in Source or Object form.
+
+   3. Grant of Patent License. Subject to the terms and conditions of
+      this License, each Contributor hereby grants to You a perpetual,
+      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
+      (except as stated in this section) patent license to make, have made,
+      use, offer to sell, sell, import, and otherwise transfer the Work,
+      where such license applies only to those patent claims licensable
+      by such Contributor that are necessarily infringed by their
+      Contribution(s) alone or by combination of their Contribution(s)
+      with the Work to which such Contribution(s) was submitted. If You
+      institute patent litigation against any entity (including a
+      cross-claim or counterclaim in a lawsuit) alleging that the Work
+      or a Contribution incorporated within the Work constitutes direct
+      or contributory patent infringement, then any patent licenses
+      granted to You under this License for that Work shall terminate
+      as of the date such litigation is filed.
+
+   4. Redistribution. You may reproduce and distribute copies of the
+      Work or Derivative Works thereof in any medium, with or without
+      modifications, and in Source or Object form, provided that You
+      meet the following conditions:
+
+      (a) You must give any other recipients of the Work or
+          Derivative Works a copy of this License; and
+
+      (b) You must cause any modified files to carry prominent notices
+          stating that You changed the files; and
+
+      (c) You must retain, in the Source form of any Derivative Works
+          that You distribute, all copyright, patent, trademark, and
+          attribution notices from the Source form of the Work,
+          excluding those notices that do not pertain to any part of
+          the Derivative Works; and
+
+      (d) If the Work includes a "NOTICE" text file as part of its
+          distribution, then any Derivative Works that You distribute must
+          include a readable copy of the attribution notices contained
+          within such NOTICE file, excluding those notices that do not
+          pertain to any part of the Derivative Works, in at least one
+          of the following places: within a NOTICE text file distributed
+          as part of the Derivative Works; within the Source form or
+          documentation, if provided along with the Derivative Works; or,
+          within a display generated by the Derivative Works, if and
+          wherever such third-party notices normally appear. The contents
+          of the NOTICE file are for informational purposes only and
+          do not modify the License. You may add Your own attribution
+          notices within Derivative Works that You distribute, alongside
+          or as an addendum to the NOTICE text from the Work, provided
+          that such additional attribution notices cannot be construed
+          as modifying the License.
+
+      You may add Your own copyright statement to Your modifications and
+      may provide additional or different license terms and conditions
+      for use, reproduction, or distribution of Your modifications, or
+      for any such Derivative Works as a whole, provided Your use,
+      reproduction, and distribution of the Work otherwise complies with
+      the conditions stated in this License.
+
+   5. Submission of Contributions. Unless You explicitly state otherwise,
+      any Contribution intentionally submitted for inclusion in the Work
+      by You to the Licensor shall be under the terms and conditions of
+      this License, without any additional terms or conditions.
+      Notwithstanding the above, nothing herein shall supersede or modify
+      the terms of any separate license agreement you may have executed
+      with Licensor regarding such Contributions.
+
+   6. Trademarks. This License does not grant permission to use the trade
+      names, trademarks, service marks, or product names of the Licensor,
+      except as required for reasonable and customary use in describing the
+      origin of the Work and reproducing the content of the NOTICE file.
+
+   7. Disclaimer of Warranty. Unless required by applicable law or
+      agreed to in writing, Licensor provides the Work (and each
+      Contributor provides its Contributions) on an "AS IS" BASIS,
+      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
+      implied, including, without limitation, any warranties or conditions
+      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
+      PARTICULAR PURPOSE. You are solely responsible for determining the
+      appropriateness of using or redistributing the Work and assume any
+      risks associated with Your exercise of permissions under this License.
+
+   8. Limitation of Liability. In no event and under no legal theory,
+      whether in tort (including negligence), contract, or otherwise,
+      unless required by applicable law (such as deliberate and grossly
+      negligent acts) or agreed to in writing, shall any Contributor be
+      liable to You for damages, including any direct, indirect, special,
+      incidental, or consequential damages of any character arising as a
+      result of this License or out of the use or inability to use the
+      Work (including but not limited to damages for loss of goodwill,
+      work stoppage, computer failure or malfunction, or any and all
+      other commercial damages or losses), even if such Contributor
+      has been advised of the possibility of such damages.
+
+   9. Accepting Warranty or Additional Liability. While redistributing
+      the Work or Derivative Works thereof, You may choose to offer,
+      and charge a fee for, acceptance of support, warranty, indemnity,
+      or other liability obligations and/or rights consistent with this
+      License. However, in accepting such obligations, You may act only
+      on Your own behalf and on Your sole responsibility, not on behalf
+      of any other Contributor, and only if You agree to indemnify,
+      defend, and hold each Contributor harmless for any liability
+      incurred by, or claims asserted against, such Contributor by reason
+      of your accepting any such warranty or additional liability.

+
+      "Derivative Works" shall mean any work, whether in Source or Object
+      form, that is based on (or derived from) the Work and for which the
+      editorial revisions, annotations, elaborations, or other modifications
+      represent, as a whole, an original work of authorship. For the purposes
+      of this License, Derivative Works shall not include works that remain

+      "Object" form shall mean any form resulting from mechanical
+      transformation or translation of a Source form, including but
+      not limited to compiled object code, generated documentation,
+      and conversions to other media types.
+
+      "Work" shall mean the work of authorship, whether in Source or
+      Object form, made available under the License, as indicated by a
+      copyright notice that is included in or attached to the work
+      (an example is provided in the Appendix below).
+
+      "Derivative Works" shall mean any work, whether in Source or Object
+      form, that is based on (or derived from) the Work and for which the
+      editorial revisions, annotations, elaborations, or other modifications
+      represent, as a whole, an original work of authorship. For the purposes
+      of this License, Derivative Works shall not include works that remain
+      separable from, or merely link (or bind by name) to the interfaces of,
+      the Work and Derivative Works thereof.
+
+      "Contribution" shall mean any work of authorship, including
+      the original version of the Work and any modifications or additions
+      to that Work or Derivative Works thereof, that is intentionally
+      submitted to Licensor for inclusion in the Work by the copyright owner
+      or by an individual or Legal Entity authorized to submit on behalf of
+      the copyright owner. For the purposes of this definition, "submitted"
+      means any form of electronic, verbal, or written communication sent
+      to the Licensor or its representatives, including but not limited to
+      communication on electronic mailing lists, source code control systems,
+      and issue tracking systems that are managed by, or on behalf of, the
+      Licensor for the purpose of discussing and improving the Work, but
+      excluding communication that is conspicuously marked or otherwise
+      designated in writing by the copyright owner as "Not a Contribution."
+
+      "Contributor" shall mean Licensor and any individual or Legal Entity
+      on behalf of whom a Contribution has been received by Licensor and
+      subsequently incorporated within the Work.
+
+   2. Grant of Copyright License. Subject to the terms and conditions of
+      this License, each Contributor hereby grants to You a perpetual,
+      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
+      copyright license to reproduce, prepare Derivative Works of,
+      publicly display, publicly perform, sublicense, and distribute the
+      Work and such Derivative Works in Source or Object form.
+
+   3. Grant of Patent License. Subject to the terms and conditions of
+      this License, each Contributor hereby grants to You a perpetual,
+      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
+      (except as stated in this section) patent license to make, have made,
+      use, offer to sell, sell, import, and otherwise transfer the Work,
+      where such license applies only to those patent claims licensable
+      by such Contributor that are necessarily infringed by their
+      Contribution(s) alone or by combination of their Contribution(s)
+      with the Work to which such Contribution(s) was submitted. If You
+      institute patent litigation against any entity (including a
+      cross-claim or counterclaim in a lawsuit) alleging that the Work
+      or a Contribution incorporated within the Work constitutes direct
+      or contributory patent infringement, then any patent licenses
+      granted to You under this License for that Work shall terminate
+      as of the date such litigation is filed.
+
+   4. Redistribution. You may reproduce and distribute copies of the
+      Work or Derivative Works thereof in any medium, with or without
+      modifications, and in Source or Object form, provided that You
+      meet the following conditions:
+
+      (a) You must give any other recipients of the Work or
+          Derivative Works a copy of this License; and
+
+      (b) You must cause any modified files to carry prominent notices
+          stating that You changed the files; and
+
+      (c) You must retain, in the Source form of any Derivative Works
+          that You distribute, all copyright, patent, trademark, and
+          attribution notices from the Source form of the Work,
+          excluding those notices that do not pertain to any part of
+          the Derivative Works; and
+
+      (d) If the Work includes a "NOTICE" text file as part of its
+          distribution, then any Derivative Works that You distribute must
+          include a readable copy of the attribution notices contained
+          within such NOTICE file, excluding those notices that do not
+          pertain to any part of the Derivative Works, in at least one
+          of the following places: within a NOTICE text file distributed
+          as part of the Derivative Works; within the Source form or
+          documentation, if provided along with the Derivative Works; or,
+          within a display generated by the Derivative Works, if and
+          wherever such third-party notices normally appear. The contents
+          of the NOTICE file are for informational purposes only and
+          do not modify the License. You may add Your own attribution
+          notices within Derivative Works that You distribute, alongside
+          or as an addendum to the NOTICE text from the Work, provided
+          that such additional attribution notices cannot be construed
+          as modifying the License.
+
+      You may add Your own copyright statement to Your modifications and
+      may provide additional or different license terms and conditions
+      for use, reproduction, or distribution of Your modifications, or
+      for any such Derivative Works as a whole, provided Your use,
+      reproduction, and distribution of the Work otherwise complies with
+      the conditions stated in this License.
+
+   5. Submission of Contributions. Unless You explicitly state otherwise,
+      any Contribution intentionally submitted for inclusion in the Work
+      by You to the Licensor shall be under the terms and conditions of
+      this License, without any additional terms or conditions.
+      Notwithstanding the above, nothing herein shall supersede or modify
+      the terms of any separate license agreement you may have executed
+      with Licensor regarding such Contributions.
+
+   6. Trademarks. This License does not grant permission to use the trade
+      names, trademarks, service marks, or product names of the Licensor,
+      except as required for reasonable and customary use in describing the
+      origin of the Work and reproducing the content of the NOTICE file.
+
+   7. Disclaimer of Warranty. Unless required by applicable law or
+      agreed to in writing, Licensor provides the Work (and each
+      Contributor provides its Contributions) on an "AS IS" BASIS,
+      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
+      implied, including, without limitation, any warranties or conditions
+      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
+      PARTICULAR PURPOSE. You are solely responsible for determining the
+      appropriateness of using or redistributing the Work and assume any
+      risks associated with Your exercise of permissions under this License.
+
+   8. Limitation of Liability. In no event and under no legal theory,
+      whether in tort (including negligence), contract, or otherwise,
+      unless required by applicable law (such as deliberate and grossly
+      negligent acts) or agreed to in writing, shall any Contributor be
+      liable to You for damages, including any direct, indirect, special,
+      incidental, or consequential damages of any character arising as a
+      result of this License or out of the use or inability to use the
+      Work (including but not limited to damages for loss of goodwill,
+      work stoppage, computer failure or malfunction, or any and all
+      other commercial damages or losses), even if such Contributor
+      has been advised of the possibility of such damages.
+
+   9. Accepting Warranty or Additional Liability. While redistributing
+      the Work or Derivative Works thereof, You may choose to offer,
+      and charge a fee for, acceptance of support, warranty, indemnity,
+      or other liability obligations and/or rights consistent with this
+      License. However, in accepting such obligations, You may act only
+      on Your own behalf and on Your sole responsibility, not on behalf
+      of any other Contributor, and only if You agree to indemnify,
+      defend, and hold each Contributor harmless for any liability
+      incurred by, or claims asserted against, such Contributor by reason
+      of your accepting any such warranty or additional liability.
+
+   END OF TERMS AND CONDITIONS

+# How To Use
+A docker container will be launched that will update the cobalt.dev source files
+in the Cobalt repository specified by the environment variable `COBALT_SRC` or
+the current working directory, which should be the root of the Cobalt
+repository, if that environment variable is not set.
+
+When the `docsite` service is run, the container will then host the updated
+cobalt.dev site locally on port `4000`.
+
+When the `docsite-build-only` service is run, the container will build and
+output the site content in the directory `out/deploy/www` at the root of the
+Cobalt directory, and copy the app.yaml deployable into `out/deploy`.
+
+# How To Run
+docker-compose build --build-arg UID=$(id -u) --build-arg GID=$(id -g) SERVICE
+
+docker-compose up SERVICE
+
+# Notes
+
+A separate docker-compose.yml was created due to the root docker-compose.yml
+being unable to locate the Gemfile in the Docker build context.
+
+The Gemfile was copied from third_party/repo-publishing-toolkit/Gemfile because
+we need to run `bundle install` with elevated permissions but if we let the
+`preview-site.sh`, which normally installs gems, run with elevated permissions
+the resulting files added or modified would not be accessible to the user who
+ran the Docker container.

+# Installing Crash Handlers in Cobalt
+
+Partners can install Crashpad's crash handlers to create crash reports in the
+cache directory. This is done by:
+
+1. Adding the following files to the `starboard_platform` target's sources:
+
+```
+'<(DEPTH)/starboard/shared/starboard/crash_handler.cc',
+'<(DEPTH)/starboard/shared/starboard/crash_handler.h',
+```
+
+2. Handling `kCobaltExtensionCrashHandlerName` in the implementation of
+`SbSystemGetExtension`:
+
+```
+#include "starboard/system.h"
+
+#include "cobalt/extension/crash_handler.h"
+#include "starboard/shared/starboard/crash_handler.h"
+
+...
+
+const void* SbSystemGetExtension(const char* name) {
+
+  ...
+
+  if (SbStringCompareAll(name, kCobaltExtensionCrashHandlerName) == 0) {
+    return starboard::common::GetCrashHandlerApi();
+  }
+  return NULL;
+}
+```
+
+3. Calling the `third_party::crashpad::wrapper::InstallCrashpadHandler()` hook
+directly after installing system crash handlers. On linux, for example, this
+could look like:
+
+```
+#include "third_party/crashpad/wrapper/wrapper.h"
+
+int main(int argc, char** argv) {
+  ...
+  starboard::shared::signal::InstallCrashSignalHandlers();
+  starboard::shared::signal::InstallSuspendSignalHandlers();
+
+  third_party::crashpad::wrapper::InstallCrashpadHandler();
+
+  int result = application.Run(argc, argv);
+  ...
+}
+```

+
+  - Enhancements:
+    Various changes to improve encoder rate control, quality and speed
+      for practically every use case.
+
+  - Bug fixes:
+    vp9-rtc: Fix color artifacts for speed >= 8.
+
+2019-01-31 v1.8.0 "Northern Shoveler Duck"
+  This release focused on encoding performance for realtime and VOD use cases.
+
+  - Upgrading:
+    This adds and improves several vp9 controls. Most are related to SVC:
+      VP9E_SET_SVC_FRAME_DROP_LAYER:
+        - Frame dropping in SVC.
+      VP9E_SET_SVC_INTER_LAYER_PRED:
+        - Inter-layer prediction in SVC.
+      VP9E_SET_SVC_GF_TEMPORAL_REF:
+        - Enable long term temporal reference in SVC.
+      VP9E_SET_SVC_REF_FRAME_CONFIG/VP9E_GET_SVC_REF_FRAME_CONFIG:
+        - Extend and improve this control for better flexibility in setting SVC
+          pattern dynamically.
+      VP9E_SET_POSTENCODE_DROP:
+        - Allow for post-encode frame dropping (applies to non-SVC too).
+      VP9E_SET_SVC_SPATIAL_LAYER_SYNC:
+        - Enable spatial layer sync frames.
+      VP9E_SET_SVC_LAYER_ID:
+        - Extend api to specify temporal id for each spatial layers.
+      VP9E_SET_ROI_MAP:
+        - Extend Region of Interest functionality to VP9.
+
+  - Enhancements:
+    2 pass vp9 encoding has improved substantially. When using --auto-alt-ref=6,
+    we see approximately 8% for VBR and 10% for CQ. When using --auto-alt-ref=1,
+    the gains are approximately 4% for VBR and 5% for CQ.
+
+    For real-time encoding, speed 7 has improved by ~5-10%. Encodes targeted at
+    screen sharing have improved when the content changes significantly (slide
+    sharing) or scrolls. There is a new speed 9 setting for mobile devices which
+    is about 10-20% faster than speed 8.
+
+  - Bug fixes:
+    VP9 denoiser issue.
+    VP9 partition issue for 1080p.
+    VP9 rate control improvments.
+    Postprocessing Multi Frame Quality Enhancement (MFQE) issue.
+    VP8 multithread decoder issues.
+    A variety of fuzzing issues.
+
+2018-01-04 v1.7.0 "Mandarin Duck"
+  This release focused on high bit depth performance (10/12 bit) and vp9
+  encoding improvements.
+
+  - Upgrading:
+    This release is ABI incompatible due to new vp9 encoder features.
+
+    Frame parallel decoding for vp9 has been removed.
+
+  - Enhancements:
+    vp9 encoding supports additional threads with --row-mt. This can be greater
+    than the number of tiles.
+
+    Two new vp9 encoder options have been added:
+      --corpus-complexity
+      --tune-content=film
+
+    Additional tooling for respecting the vp9 "level" profiles has been added.
+
+  - Bug fixes:
+    A variety of fuzzing issues.
+    vp8 threading fix for ARM.
+    Codec control VP9_SET_SKIP_LOOP_FILTER fixed.
+    Reject invalid multi resolution configurations.
+
+2017-01-09 v1.6.1 "Long Tailed Duck"
+  This release improves upon the VP9 encoder and speeds up the encoding and
+  decoding processes.
+
+  - Upgrading:
+    This release is ABI compatible with 1.6.0.
+
+  - Enhancements:
+    Faster VP9 encoding and decoding.
+    High bit depth builds now provide similar speed for 8 bit encode and decode
+    for x86 targets. Other platforms and higher bit depth improvements are in
+    progress.
+
+  - Bug Fixes:
+    A variety of fuzzing issues.
+
+2016-07-20 v1.6.0 "Khaki Campbell Duck"
+  This release improves upon the VP9 encoder and speeds up the encoding and
+  decoding processes.
+
+  - Upgrading:
+    This release is ABI incompatible with 1.5.0 due to a new 'color_range' enum
+    in vpx_image and some minor changes to the VP8_COMP structure.
+
+    The default key frame interval for VP9 has changed from 128 to 9999.
+
+  - Enhancement:
+    A core focus has been performance for low end Intel processors. SSSE3
+    instructions such as 'pshufb' have been avoided and instructions have been
+    reordered to better accommodate the more constrained pipelines.
+
+    As a result, devices based on Celeron processors have seen substantial
+    decoding improvements. From Indian Runner Duck to Javan Whistling Duck,
+    decoding speed improved between 10 and 30%. Between Javan Whistling Duck
+    and Khaki Campbell Duck, it improved another 10 to 15%.
+
+    While Celeron benefited most, Core-i5 also improved 5% and 10% between the
+    respective releases.
+
+    Realtime performance for WebRTC for both speed and quality has received a
+    lot of attention.
+
+  - Bug Fixes:
+    A number of fuzzing issues, found variously by Mozilla, Chromium and others,
+    have been fixed and we strongly recommend updating.
+
+2015-11-09 v1.5.0 "Javan Whistling Duck"
+  This release improves upon the VP9 encoder and speeds up the encoding and
+  decoding processes.
+
+  - Upgrading:
+    This release is ABI incompatible with 1.4.0. It drops deprecated VP8
+    controls and adds a variety of VP9 controls for testing.
+
+    The vpxenc utility now prefers VP9 by default.
+
+  - Enhancements:
+    Faster VP9 encoding and decoding
+    Smaller library size by combining functions used by VP8 and VP9
+
+  - Bug Fixes:
+    A variety of fuzzing issues
+
+2015-04-03 v1.4.0 "Indian Runner Duck"
+  This release includes significant improvements to the VP9 codec.
+
+  - Upgrading:
+    This release is ABI incompatible with 1.3.0. It drops the compatibility
+    layer, requiring VPX_IMG_FMT_* instead of IMG_FMT_*, and adds several codec
+    controls for VP9.
+
+  - Enhancements:
+    Faster VP9 encoding and decoding
+    Multithreaded VP9 decoding (tile and frame-based)
+    Multithreaded VP9 encoding - on by default
+    YUV 4:2:2 and 4:4:4 support in VP9
+    10 and 12bit support in VP9
+    64bit ARM support by replacing ARM assembly with intrinsics
+
+  - Bug Fixes:
+    Fixes a VP9 bitstream issue in Profile 1. This only affected non-YUV 4:2:0
+    files.
+
+  - Known Issues:
+    Frame Parallel decoding fails for segmented and non-420 files.
+
+2013-11-15 v1.3.0 "Forest"
+  This release introduces the VP9 codec in a backward-compatible way.
+  All existing users of VP8 can continue to use the library without
+  modification. However, some VP8 options do not map to VP9 in the same manner.
+
+  The VP9 encoder in this release is not feature complete. Users interested in
+  the encoder are advised to use the git master branch and discuss issues on
+  libvpx mailing lists.
+
+  - Upgrading:
+    This release is ABI and API compatible with Duclair (v1.0.0). Users
+    of older releases should refer to the Upgrading notes in this document
+    for that release.
+
+  - Enhancements:
+      Get rid of bashisms in the main build scripts
+      Added usage info on command line options
+      Add lossless compression mode
+      Dll build of libvpx

+      configure: default configure log to config.log
+      Add encoding option --static-thresh
+
+  - Speed:
+      Miscellaneous speed optimizations for VP8 and VP9.
+
+  - Quality:
+      In general, quality is consistent with the Eider release.
+
+  - Bug Fixes:
+      This release represents approximately a year of engineering effort,
+      and contains multiple bug fixes. Please refer to git history for details.
+
+
+2012-12-21 v1.2.0
+  This release acts as a checkpoint for a large amount of internal refactoring
+  and testing. It also contains a number of small bugfixes, so all users are
+  encouraged to upgrade.
+
+  - Upgrading:
+    This release is ABI and API compatible with Duclair (v1.0.0). Users
+    of older releases should refer to the Upgrading notes in this
+    document for that release.
+
+  - Enhancements:
+      VP8 optimizations for MIPS dspr2
+      vpxenc: add -quiet option
+
+  - Speed:

+
+      Minor tweaks to ARNR filtering
+      Minor improvements to real time encoding with multiple temporal layers
+
+  - Bug Fixes:
+      Fixes multithreaded encoder race condition in loopfilter
+      Fixes multi-resolution threaded encoding
+      Fix potential encoder dead-lock after picture resize
+
+
+2012-05-09 v1.1.0 "Eider"
+  This introduces a number of enhancements, mostly focused on real-time
+  encoding. In addition, it fixes a decoder bug (first introduced in
+  Duclair) so all users of that release are encouraged to upgrade.
+
+  - Upgrading:
+    This release is ABI and API compatible with Duclair (v1.0.0). Users
+    of older releases should refer to the Upgrading notes in this
+    document for that release.
+
+    This release introduces a new temporal denoiser, controlled by the
+    VP8E_SET_NOISE_SENSITIVITY control. The temporal denoiser does not
+    currently take a strength parameter, so the control is effectively
+    a boolean - zero (off) or non-zero (on). For compatibility with
+    existing applications, the values accepted are the same as those
+    for the spatial denoiser (0-6). The temporal denoiser is enabled
+    by default, and the older spatial denoiser may be restored by
+    configuring with --disable-temporal-denoising. The temporal denoiser
+    is more computationally intensive than the spatial one.
+
+    This release removes support for a legacy, decode only API that was
+    supported, but deprecated, at the initial release of libvpx
+    (v0.9.0). This is not expected to have any impact. If you are
+    impacted, you can apply a reversion to commit 2bf8fb58 locally.
+    Please update to the latest libvpx API if you are affected.
+
+  - Enhancements:
+      Adds a motion compensated temporal denoiser to the encoder, which
+      gives higher quality than the older spatial denoiser. (See above
+      for notes on upgrading).
+
+      In addition, support for new compilers and platforms were added,
+      including:
+        improved support for XCode
+        Android x86 NDK build
+        OS/2 support
+        SunCC support
+
+      Changing resolution with vpx_codec_enc_config_set() is now
+      supported. Previously, reinitializing the codec was required to
+      change the input resolution.
+
+      The vpxenc application has initial support for producing multiple
+      encodes from the same input in one call. Resizing is not yet
+      supported, but varying other codec parameters is. Use -- to
+      delineate output streams. Options persist from one stream to the
+      next.
+
+      Also, the vpxenc application will now use a keyframe interval of
+      5 seconds by default. Use the --kf-max-dist option to override.
+
+  - Speed:
+      Decoder performance improved 2.5% versus Duclair. Encoder speed is
+      consistent with Duclair for most material. Two pass encoding of
+      slideshow-like material will see significant improvements.
+
+      Large realtime encoding speed gains at a small quality expense are
+      possible by configuring the on-the-fly bitpacking experiment with
+      --enable-onthefly-bitpacking. Realtime encoder can be up to 13%
+      faster (ARM) depending on the number of threads and bitrate
+      settings. This technique sees constant gain over the 5-16 speed
+      range. For VC style input the loss seen is up to 0.2dB. See commit
+      52cf4dca for further details.
+
+  - Quality:
+      On the whole, quality is consistent with the Duclair release. Some
+      tweaks:
+
+        Reduced blockiness in easy sections by applying a penalty to
+        intra modes.
+
+        Improved quality of static sections (like slideshows) with
+        two pass encoding.
+
+        Improved keyframe sizing with multiple temporal layers
+
+  - Bug Fixes:
+      Corrected alt-ref contribution to frame rate for visible updates
+      to the alt-ref buffer. This affected applications making manual
+      usage of the frame reference flags, or temporal layers.
+
+      Additional constraints were added to disable multi-frame quality
+      enhancement (MFQE) in sections of the frame where there is motion.
+      (#392)
+
+      Fixed corruption issues when vpx_codec_enc_config_set() was called
+      with spatial resampling enabled.
+
+      Fixed a decoder error introduced in Duclair where the segmentation
+      map was not being reinitialized on keyframes (#378)
+
+
+2012-01-27 v1.0.0 "Duclair"
+  Our fourth named release, focused on performance and features related to
+  real-time encoding. It also fixes a decoder crash bug introduced in
+  v0.9.7, so all users of that release are encouraged to upgrade.
+
+  - Upgrading:
+      This release is ABI incompatible with prior releases of libvpx, so the
+      "major" version number has been bumped to 1. You must recompile your
+      applications against the latest version of the libvpx headers. The
+      API remains compatible, and this should not require code changes in most
+      applications.
+
+  - Enhancements:
+      This release introduces several substantial new features to the encoder,
+      of particular interest to real time streaming applications.
+
+      Temporal scalability allows the encoder to produce a stream that can
+      be decimated to different frame rates, with independent rate targeting
+      for each substream.
+
+      Multiframe quality enhancement postprocessing can make visual quality
+      more consistent in the presence of frames that are substantially
+      different quality than the surrounding frames, as in the temporal
+      scalability case and in some forced keyframe scenarios.
+
+      Multiple-resolution encoding support allows the encoding of the
+      same content at different resolutions faster than encoding them
+      separately.
+
+  - Speed:
+      Optimization targets for this release included the decoder and the real-
+      time modes of the encoder. Decoder speed on x86 has improved 10.5% with
+      this release. Encoder improvements followed a curve where speeds 1-3
+      improved 4.0%-1.5%, speeds 4-8 improved <1%, and speeds 9-16 improved
+      1.5% to 10.5%, respectively. "Best" mode speed is consistent with the
+      Cayuga release.
+
+  - Quality:
+      Encoder quality in the single stream case is consistent with the Cayuga
+      release.
+
+  - Bug Fixes:
+      This release fixes an OOB read decoder crash bug present in v0.9.7
+      related to the clamping of motion vectors in SPLITMV blocks. This
+      behavior could be triggered by corrupt input or by starting
+      decoding from a P-frame.
+
+
+2011-08-15 v0.9.7-p1 "Cayuga" patch 1
+  This is an incremental bugfix release against Cayuga. All users of that
+  release are strongly encouraged to upgrade.
+
+    - Fix potential OOB reads (cdae03a)
+
+          An unbounded out of bounds read was discovered when the
+          decoder was requested to perform error concealment (new in
+          Cayuga) given a frame with corrupt partition sizes.
+
+          A bounded out of bounds read was discovered affecting all
+          versions of libvpx. Given an multipartition input frame that
+          is truncated between the mode/mv partition and the first
+          residiual paritition (in the block of partition offsets), up
+          to 3 extra bytes could have been read from the source buffer.
+          The code will not take any action regardless of the contents
+          of these undefined bytes, as the truncated buffer is detected
+          immediately following the read based on the calculated
+          starting position of the coefficient partition.
+
+    - Fix potential error concealment crash when the very first frame
+      is missing or corrupt (a609be5)
+
+    - Fix significant artifacts in error concealment (a4c2211, 99d870a)
+
+    - Revert 1-pass CBR rate control changes (e961317)
+      Further testing showed this change produced undesirable visual
+      artifacts, rolling back for now.
+
+
+2011-08-02 v0.9.7 "Cayuga"
+  Our third named release, focused on a faster, higher quality, encoder.
+
+  - Upgrading:
+    This release is backwards compatible with Aylesbury (v0.9.5) and
+    Bali (v0.9.6). Users of older releases should refer to the Upgrading
+    notes in this document for that release.
+
+  - Enhancements:
+          Stereo 3D format support for vpxenc
+          Runtime detection of available processor cores.
+          Allow specifying --end-usage by enum name
+          vpxdec: test for frame corruption
+          vpxenc: add quantizer histogram display
+          vpxenc: add rate histogram display
+          Set VPX_FRAME_IS_DROPPABLE
+          update configure for ios sdk 4.3
+          Avoid text relocations in ARM vp8 decoder
+          Generate a vpx.pc file for pkg-config.
+          New ways of passing encoded data between encoder and decoder.
+
+  - Speed:
+      This release includes across-the-board speed improvements to the
+      encoder. On x86, these measure at approximately 11.5% in Best mode,
+      21.5% in Good mode (speed 0), and 22.5% in Realtime mode (speed 6).
+      On ARM Cortex A9 with Neon extensions, real-time encoding of video
+      telephony content is 35% faster than Bali on single core and 48%
+      faster on multi-core. On the NVidia Tegra2 platform, real time
+      encoding is 40% faster than Bali.
+
+      Decoder speed was not a priority for this release, but improved
+      approximately 8.4% on x86.
+
+          Reduce motion vector search on alt-ref frame.
+          Encoder loopfilter running in its own thread
+          Reworked loopfilter to precalculate more parameters

+          Improve SSE2 half-pixel filter funtions
+          Add vp8_sub_pixel_variance16x8_ssse3 function
+          Reduce unnecessary distortion computation
+          Use diamond search to replace full search
+          Preload reference area in sub-pixel motion search (real-time mode)
+
+  - Quality:
+      This release focused primarily on one-pass use cases, including
+      video conferencing. Low latency data rate control was significantly
+      improved, improving streamability over bandwidth constrained links.
+      Added support for error concealment, allowing frames to maintain
+      visual quality in the presence of substantial packet loss.
+
+          Add rc_max_intra_bitrate_pct control
+          Limit size of initial keyframe in one-pass.
+          Improve framerate adaptation

+          Fix vpxenc encoding incorrect webm file header on big endian
+
+
+2011-03-07 v0.9.6 "Bali"
+  Our second named release, focused on a faster, higher quality, encoder.
+
+  - Upgrading:
+    This release is backwards compatible with Aylesbury (v0.9.5). Users
+    of older releases should refer to the Upgrading notes in this
+    document for that release.

+      implemented error tracking in the decoder
+      fix pipe support on windows
+
+  - Speed:
+      Primary focus was on good quality mode, speed 0. Average improvement
+      on x86 about 40%, up to 100% on user-generated content at that speed.
+      Best quality mode speed improved 35%, and realtime speed 10-20%. This
+      release also saw significant improvement in realtime encoding speed
+      on ARM platforms.
+
+        Improved encoder threading
+        Dont pick encoder filter level when loopfilter is disabled.
+        Avoid double copying of key frames into alt and golden buffer

+
+  - Quality:
+      Best quality mode improved PSNR 6.3%, and SSIM 6.1%. This release
+      also includes support for "activity masking," which greatly improves
+      SSIM at the expense of PSNR. For now, this feature is available with
+      the --tune=ssim option. Further experimentation in this area
+      is ongoing. This release also introduces a new rate control mode
+      called "CQ," which changes the allocation of bits within a clip to
+      the sections where they will have the most visual impact.
+
+        Tuning for the more exact quantizer.
+        Relax rate control for last few frames
+        CQ Mode
+        Limit key frame quantizer for forced key frames.
+        KF/GF Pulsing
+        Add simple version of activity masking.
+        make rdmult adaptive for intra in quantizer RDO
+        cap the best quantizer for 2nd order DC
+        change the threshold of DC check for encode breakout
+
+  - Bug Fixes:
+      Fix crash on Sparc Solaris.
+      Fix counter of fixed keyframe distance
+      ARNR filter pointer update bug fix
+      Fixed use of motion percentage in KF/GF group calc
+      Changed condition for using RD in Intra Mode
+      Fix encoder real-time only configuration.
+      Fix ARM encoder crash with multiple token partitions
+      Fixed bug first cluster timecode of webm file is wrong.
+      Fixed various encoder bugs with odd-sized images
+      vp8e_get_preview fixed when spatial resampling enabled
+      quantizer: fix assertion in fast quantizer path
+      Allocate source buffers to be multiples of 16
+      Fix for manual Golden frame frequency
+      Fix drastic undershoot in long form content
+
+
+2010-10-28 v0.9.5 "Aylesbury"
+  Our first named release, focused on a faster decoder, and a better encoder.
+
+  - Upgrading:
+    This release incorporates backwards-incompatible changes to the
+    ivfenc and ivfdec tools. These tools are now called vpxenc and vpxdec.
+
+    vpxdec
+      * the -q (quiet) option has been removed, and replaced with
+        -v (verbose). the output is quiet by default. Use -v to see
+        the version number of the binary.
+
+      * The default behavior is now to write output to a single file
+        instead of individual frames. The -y option has been removed.
+        Y4M output is the default.
+
+      * For raw I420/YV12 output instead of Y4M, the --i420 or --yv12
+        options must be specified.
+
+          $ ivfdec -o OUTPUT INPUT
+          $ vpxdec --i420 -o OUTPUT INPUT
+
+      * If an output file is not specified, the default is to write
+        Y4M to stdout. This makes piping more natural.
+
+          $ ivfdec -y -o - INPUT | ...
+          $ vpxdec INPUT | ...
+
+      * The output file has additional flexibility for formatting the
+        filename. It supports escape characters for constructing a
+        filename from the width, height, and sequence number. This
+        replaces the -p option. To get the equivalent:
+
+          $ ivfdec -p frame INPUT
+          $ vpxdec --i420 -o frame-%wx%h-%4.i420 INPUT
+
+    vpxenc
+      * The output file must be specified with -o, rather than as the
+        last argument.
+
+          $ ivfenc <options> INPUT OUTPUT
+          $ vpxenc <options> -o OUTPUT INPUT
+
+      * The output defaults to webm. To get IVF output, use the --ivf
+        option.
+
+          $ ivfenc <options> INPUT OUTPUT.ivf
+          $ vpxenc <options> -o OUTPUT.ivf --ivf INPUT
+
+
+  - Enhancements:
+      ivfenc and ivfdec have been renamed to vpxenc, vpxdec.
+      vpxdec supports .webm input
+      vpxdec writes .y4m by default
+      vpxenc writes .webm output by default
+      vpxenc --psnr now shows the average/overall PSNR at the end
+      ARM platforms now support runtime cpu detection
+      vpxdec visualizations added for motion vectors, block modes, references
+      vpxdec now silent by default
+      vpxdec --progress shows frame-by-frame timing information
+      vpxenc supports the distinction between --fps and --timebase

+README - 9 December 2019
+
+Welcome to the WebM VP8/VP9 Codec SDK!
+
+COMPILING THE APPLICATIONS/LIBRARIES:
+  The build system used is similar to autotools. Building generally consists of
+  "configuring" with your desired build options, then using GNU make to build
+  the application.
+
+  1. Prerequisites
+
+    * All x86 targets require the Yasm[1] assembler be installed[2].
+    * All Windows builds require that Cygwin[3] be installed.
+    * Building the documentation requires Doxygen[4]. If you do not
+      have this package, the install-docs option will be disabled.
+    * Downloading the data for the unit tests requires curl[5] and sha1sum.
+      sha1sum is provided via the GNU coreutils, installed by default on
+      many *nix platforms, as well as MinGW and Cygwin. If coreutils is not
+      available, a compatible version of sha1sum can be built from
+      source[6]. These requirements are optional if not running the unit
+      tests.
+
+    [1]: http://www.tortall.net/projects/yasm
+    [2]: For Visual Studio the base yasm binary (not vsyasm) should be in the
+         PATH for Visual Studio. For VS2017 it is sufficient to rename
+         yasm-<version>-<arch>.exe to yasm.exe and place it in:
+         Program Files (x86)/Microsoft Visual Studio/2017/<level>/Common7/Tools/
+    [3]: http://www.cygwin.com
+    [4]: http://www.doxygen.org
+    [5]: http://curl.haxx.se
+    [6]: http://www.microbrew.org/tools/md5sha1sum/
+
+  2. Out-of-tree builds
+  Out of tree builds are a supported method of building the application. For
+  an out of tree build, the source tree is kept separate from the object
+  files produced during compilation. For instance:
+
+    $ mkdir build
+    $ cd build
+    $ ../libvpx/configure <options>
+    $ make
+
+  3. Configuration options
+  The 'configure' script supports a number of options. The --help option can be
+  used to get a list of supported options:
+    $ ../libvpx/configure --help
+
+  4. Compiler analyzers
+  Compilers have added sanitizers which instrument binaries with information
+  about address calculation, memory usage, threading, undefined behavior, and
+  other common errors. To simplify building libvpx with some of these features
+  use tools/set_analyzer_env.sh before running configure. It will set the
+  compiler and necessary flags for building as well as environment variables
+  read by the analyzer when testing the binaries.
+    $ source ../libvpx/tools/set_analyzer_env.sh address
+
+  5. Cross development
+  For cross development, the most notable option is the --target option. The
+  most up-to-date list of supported targets can be found at the bottom of the
+  --help output of the configure script. As of this writing, the list of
+  available targets is:
+
+    arm64-android-gcc
+    arm64-darwin-gcc
+    arm64-linux-gcc
+    arm64-win64-gcc
+    arm64-win64-vs15
+    armv7-android-gcc
+    armv7-darwin-gcc
+    armv7-linux-rvct
+    armv7-linux-gcc
+    armv7-none-rvct
+    armv7-win32-gcc
+    armv7-win32-vs14
+    armv7-win32-vs15
+    armv7s-darwin-gcc
+    armv8-linux-gcc
+    mips32-linux-gcc
+    mips64-linux-gcc
+    ppc64le-linux-gcc
+    sparc-solaris-gcc
+    x86-android-gcc
+    x86-darwin8-gcc
+    x86-darwin8-icc
+    x86-darwin9-gcc
+    x86-darwin9-icc
+    x86-darwin10-gcc
+    x86-darwin11-gcc
+    x86-darwin12-gcc
+    x86-darwin13-gcc
+    x86-darwin14-gcc
+    x86-darwin15-gcc
+    x86-darwin16-gcc
+    x86-darwin17-gcc
+    x86-iphonesimulator-gcc
+    x86-linux-gcc
+    x86-linux-icc
+    x86-os2-gcc
+    x86-solaris-gcc
+    x86-win32-gcc
+    x86-win32-vs14
+    x86-win32-vs15
+    x86-win32-vs16
+    x86_64-android-gcc
+    x86_64-darwin9-gcc
+    x86_64-darwin10-gcc
+    x86_64-darwin11-gcc
+    x86_64-darwin12-gcc
+    x86_64-darwin13-gcc
+    x86_64-darwin14-gcc
+    x86_64-darwin15-gcc
+    x86_64-darwin16-gcc
+    x86_64-darwin17-gcc
+    x86_64-darwin18-gcc
+    x86_64-darwin19-gcc
+    x86_64-iphonesimulator-gcc
+    x86_64-linux-gcc
+    x86_64-linux-icc
+    x86_64-solaris-gcc
+    x86_64-win64-gcc
+    x86_64-win64-vs14
+    x86_64-win64-vs15
+    x86_64-win64-vs16
+    generic-gnu
+
+  The generic-gnu target, in conjunction with the CROSS environment variable,
+  can be used to cross compile architectures that aren't explicitly listed, if
+  the toolchain is a cross GNU (gcc/binutils) toolchain. Other POSIX toolchains
+  will likely work as well. For instance, to build using the mipsel-linux-uclibc
+  toolchain, the following command could be used (note, POSIX SH syntax, adapt
+  to your shell as necessary):
+
+    $ CROSS=mipsel-linux-uclibc- ../libvpx/configure
+
+  In addition, the executables to be invoked can be overridden by specifying the
+  environment variables: CC, AR, LD, AS, STRIP, NM. Additional flags can be
+  passed to these executables with CFLAGS, LDFLAGS, and ASFLAGS.
+
+  6. Configuration errors
+  If the configuration step fails, the first step is to look in the error log.
+  This defaults to config.log. This should give a good indication of what went
+  wrong. If not, contact us for support.
+
+VP8/VP9 TEST VECTORS:
+  The test vectors can be downloaded and verified using the build system after
+  running configure. To specify an alternate directory the
+  LIBVPX_TEST_DATA_PATH environment variable can be used.
+
+  $ ./configure --enable-unit-tests
+  $ LIBVPX_TEST_DATA_PATH=../libvpx-test-data make testdata
+
+CODE STYLE:
+  The coding style used by this project is enforced with clang-format using the
+  configuration contained in the .clang-format file in the root of the
+  repository.
+
+  Before pushing changes for review you can format your code with:
+  # Apply clang-format to modified .c, .h and .cc files
+  $ clang-format -i --style=file \
+    $(git diff --name-only --diff-filter=ACMR '*.[hc]' '*.cc')
+
+  Check the .clang-format file for the version used to generate it if there is
+  any difference between your local formatting and the review system.
+
+  See also: http://clang.llvm.org/docs/ClangFormat.html
+
+SUPPORT
+  This library is an open source project supported by its community. Please

+# This file is to be used for compiling libvpx for Android using the NDK.
+# In an Android project place a libvpx checkout in the jni directory.
+# Run the configure script from the jni directory.  Base libvpx
+# encoder/decoder configuration will look similar to:
+# ./libvpx/configure --target=armv7-android-gcc --disable-examples \
+#                    --enable-external-build
+#
+# When targeting Android, realtime-only is enabled by default.  This can
+# be overridden by adding the command line flag:
+#  --disable-realtime-only
+#
+# This will create .mk files that contain variables that contain the
+# source files to compile.
+#
+# Place an Android.mk file in the jni directory that references the
+# Android.mk file in the libvpx directory:
+# LOCAL_PATH := $(call my-dir)
+# include $(CLEAR_VARS)
+# include jni/libvpx/build/make/Android.mk
+#
+# By default libvpx will use the 'cpufeatures' module from the NDK. This allows
+# the library to be built with all available optimizations (SSE2->AVX512 for
+# x86, NEON for arm, DSPr2 for mips). This can be disabled with
+#   --disable-runtime-cpu-detect
+# but the resulting library *must* be run on devices supporting all of the
+# enabled extensions. They can be disabled individually with
+#   --disable-{sse2, sse3, ssse3, sse4_1, avx, avx2, avx512}
+#   --disable-neon[-asm]

+##  configure
+##
+##  This script is the front-end to the build system. It provides a similar
+##  interface to standard configure scripts with some extra bits for dealing
+##  with toolchains that differ from the standard POSIX interface and
+##  for extracting subsets of the source tree. In theory, reusable parts
+##  of this script were intended to live in build/make/configure.sh,
+##  but in practice, the line is pretty blurry.
+##
+##  This build system is based in part on the FFmpeg configure script.

+// Frame-by-frame MD5 Checksum
+// ===========================
+//
+// This example builds upon the simple decoder loop to show how checksums
+// of the decoded output can be generated. These are used for validating
+// decoder implementations against the reference implementation, for example.
+//
+// MD5 algorithm
+// -------------
+// The Message-Digest 5 (MD5) is a well known hash function. We have provided
+// an implementation derived from the RSA Data Security, Inc. MD5 Message-Digest
+// Algorithm for your use. Our implmentation only changes the interface of this
+// reference code. You must include the `md5_utils.h` header for access to these
+// functions.
+//
+// Processing The Decoded Data
+// ---------------------------
+// Each row of the image is passed to the MD5 accumulator. First the Y plane
+// is processed, then U, then V. It is important to honor the image's `stride`
+// values.

+// Decode With Drops Example
+// =========================
+//
+// This is an example utility which drops a series of frames, as specified
+// on the command line. This is useful for observing the error recovery
+// features of the codec.
+//
+// Usage
+// -----
+// This example adds a single argument to the `simple_decoder` example,
+// which specifies the range or pattern of frames to drop. The parameter is
+// parsed as follows:
+//
+// Dropping A Range Of Frames
+// --------------------------
+// To drop a range of frames, specify the starting frame and the ending
+// frame to drop, separated by a dash. The following command will drop
+// frames 5 through 10 (base 1).
+//
+//  $ ./decode_with_drops in.ivf out.i420 5-10
+//
+//
+// Dropping A Pattern Of Frames
+// ----------------------------
+// To drop a pattern of frames, specify the number of frames to drop and
+// the number of frames after which to repeat the pattern, separated by
+// a forward-slash. The following command will drop 3 of 7 frames.
+// Specifically, it will decode 4 frames, then drop 3 frames, and then
+// repeat.
+//
+//  $ ./decode_with_drops in.ivf out.i420 3/7
+//
+//
+// Extra Variables
+// ---------------
+// This example maintains the pattern passed on the command line in the
+// `n`, `m`, and `is_range` variables:
+//
+//
+// Making The Drop Decision
+// ------------------------
+// The example decides whether to drop the frame based on the current
+// frame number, immediately before decoding the frame.

+// Postprocessing Decoder
+// ======================
+//
+// This example adds postprocessing to the simple decoder loop.
+//
+// Initializing Postprocessing
+// ---------------------------
+// You must inform the codec that you might request postprocessing at
+// initialization time. This is done by passing the VPX_CODEC_USE_POSTPROC
+// flag to `vpx_codec_dec_init`. If the codec does not support
+// postprocessing, this call will return VPX_CODEC_INCAPABLE. For
+// demonstration purposes, we also fall back to default initialization if
+// the codec does not provide support.
+//
+// Using Adaptive Postprocessing
+// -----------------------------
+// VP6 provides "adaptive postprocessing." It will automatically select the
+// best postprocessing filter on a frame by frame basis based on the amount
+// of time remaining before the user's specified deadline expires. The
+// special value 0 indicates that the codec should take as long as
+// necessary to provide the best quality frame. This example gives the
+// codec 15ms (15000us) to return a frame. Remember that this is a soft
+// deadline, and the codec may exceed it doing its regular processing. In
+// these cases, no additional postprocessing will be done.
+//
+// Codec Specific Postprocessing Controls
+// --------------------------------------
+// Some codecs provide fine grained controls over their built-in
+// postprocessors. VP8 is one example. The following sample code toggles
+// postprocessing on and off every 15 frames.

+// VP8 Set Active and ROI Maps
+// ===========================
+//
+// This is an example demonstrating how to control the VP8 encoder's
+// ROI and Active maps.
+//
+// ROI (Reigon of Interest) maps are a way for the application to assign
+// each macroblock in the image to a region, and then set quantizer and
+// filtering parameters on that image.
+//
+// Active maps are a way for the application to specify on a
+// macroblock-by-macroblock basis whether there is any activity in that
+// macroblock.
+//
+//
+// Configuration
+// -------------
+// An ROI map is set on frame 22. If the width of the image in macroblocks
+// is evenly divisble by 4, then the output will appear to have distinct
+// columns, where the quantizer, loopfilter, and static threshold differ
+// from column to column.
+//
+// An active map is set on frame 33. If the width of the image in macroblocks
+// is evenly divisble by 4, then the output will appear to have distinct
+// columns, where one column will have motion and the next will not.
+//
+// The active map is cleared on frame 44.
+//
+// Observing The Effects
+// ---------------------
+// Use the `simple_decoder` example to decode this sample, and observe
+// the change in the image at frames 22, 33, and 44.

+// Simple Decoder
+// ==============
+//
+// This is an example of a simple decoder loop. It takes an input file
+// containing the compressed data (in IVF format), passes it through the
+// decoder, and writes the decompressed frames to disk. Other decoder
+// examples build upon this one.
+//
+// The details of the IVF format have been elided from this example for
+// simplicity of presentation, as IVF files will not generally be used by
+// your application. In general, an IVF file consists of a file header,
+// followed by a variable number of frames. Each frame consists of a frame
+// header followed by a variable length payload. The length of the payload
+// is specified in the first four bytes of the frame header. The payload is
+// the raw compressed data.
+//
+// Standard Includes
+// -----------------
+// For decoders, you only have to include `vpx_decoder.h` and then any
+// header files for the specific codecs you use. In this case, we're using
+// vp8.
+//
+// Initializing The Codec
+// ----------------------
+// The libvpx decoder is initialized by the call to vpx_codec_dec_init().
+// Determining the codec interface to use is handled by VpxVideoReader and the
+// functions prefixed with vpx_video_reader_. Discussion of those functions is
+// beyond the scope of this example, but the main gist is to open the input file
+// and parse just enough of it to determine if it's a VPx file and which VPx
+// codec is contained within the file.
+// Note the NULL pointer passed to vpx_codec_dec_init(). We do that in this
+// example because we want the algorithm to determine the stream configuration
+// (width/height) and allocate memory automatically.
+//
+// Decoding A Frame
+// ----------------
+// Once the frame has been read into memory, it is decoded using the
+// `vpx_codec_decode` function. The call takes a pointer to the data
+// (`frame`) and the length of the data (`frame_size`). No application data
+// is associated with the frame in this example, so the `user_priv`
+// parameter is NULL. The `deadline` parameter is left at zero for this
+// example. This parameter is generally only used when doing adaptive post
+// processing.
+//
+// Codecs may produce a variable number of output frames for every call to
+// `vpx_codec_decode`. These frames are retrieved by the
+// `vpx_codec_get_frame` iterator function. The iterator variable `iter` is
+// initialized to NULL each time `vpx_codec_decode` is called.
+// `vpx_codec_get_frame` is called in a loop, returning a pointer to a
+// decoded image or NULL to indicate the end of list.
+//
+// Processing The Decoded Data
+// ---------------------------
+// In this example, we simply write the encoded data to disk. It is
+// important to honor the image's `stride` values.
+//
+// Cleanup
+// -------
+// The `vpx_codec_destroy` call frees any memory allocated by the codec.
+//
+// Error Handling
+// --------------
+// This example does not special case any error return codes. If there was
+// an error, a descriptive message is printed and the program exits. With
+// few exceptions, vpx_codec functions return an enumerated error status,
+// with the value `0` indicating success.

+// Simple Encoder
+// ==============
+//
+// This is an example of a simple encoder loop. It takes an input file in
+// YV12 format, passes it through the encoder, and writes the compressed
+// frames to disk in IVF format. Other decoder examples build upon this
+// one.
+//
+// The details of the IVF format have been elided from this example for
+// simplicity of presentation, as IVF files will not generally be used by
+// your application. In general, an IVF file consists of a file header,
+// followed by a variable number of frames. Each frame consists of a frame
+// header followed by a variable length payload. The length of the payload
+// is specified in the first four bytes of the frame header. The payload is
+// the raw compressed data.
+//
+// Standard Includes
+// -----------------
+// For encoders, you only have to include `vpx_encoder.h` and then any
+// header files for the specific codecs you use. In this case, we're using
+// vp8.
+//
+// Getting The Default Configuration
+// ---------------------------------
+// Encoders have the notion of "usage profiles." For example, an encoder
+// may want to publish default configurations for both a video
+// conferencing application and a best quality offline encoder. These
+// obviously have very different default settings. Consult the
+// documentation for your codec to see if it provides any default
+// configurations. All codecs provide a default configuration, number 0,
+// which is valid for material in the vacinity of QCIF/QVGA.
+//
+// Updating The Configuration
+// ---------------------------------
+// Almost all applications will want to update the default configuration
+// with settings specific to their usage. Here we set the width and height
+// of the video file to that specified on the command line. We also scale
+// the default bitrate based on the ratio between the default resolution
+// and the resolution specified on the command line.
+//
+// Initializing The Codec
+// ----------------------
+// The encoder is initialized by the following code.
+//
+// Encoding A Frame
+// ----------------
+// The frame is read as a continuous block (size width * height * 3 / 2)
+// from the input file. If a frame was read (the input file has not hit
+// EOF) then the frame is passed to the encoder. Otherwise, a NULL
+// is passed, indicating the End-Of-Stream condition to the encoder. The
+// `frame_cnt` is reused as the presentation time stamp (PTS) and each
+// frame is shown for one frame-time in duration. The flags parameter is
+// unused in this example. The deadline is set to VPX_DL_REALTIME to
+// make the example run as quickly as possible.
+
+// Forced Keyframes
+// ----------------
+// Keyframes can be forced by setting the VPX_EFLAG_FORCE_KF bit of the
+// flags passed to `vpx_codec_control()`. In this example, we force a
+// keyframe every <keyframe-interval> frames. Note, the output stream can
+// contain additional keyframes beyond those that have been forced using the
+// VPX_EFLAG_FORCE_KF flag because of automatic keyframe placement by the
+// encoder.
+//
+// Processing The Encoded Data
+// ---------------------------
+// Each packet of type `VPX_CODEC_CX_FRAME_PKT` contains the encoded data
+// for this frame. We write a IVF frame header, followed by the raw data.
+//
+// Cleanup
+// -------
+// The `vpx_codec_destroy` call frees any memory allocated by the codec.
+//
+// Error Handling
+// --------------
+// This example does not special case any error return codes. If there was
+// an error, a descriptive message is printed and the program exits. With
+// few exeptions, vpx_codec functions return an enumerated error status,
+// with the value `0` indicating success.
+//
+// Error Resiliency Features
+// -------------------------
+// Error resiliency is controlled by the g_error_resilient member of the
+// configuration structure. Use the `decode_with_drops` example to decode with
+// frames 5-10 dropped. Compare the output for a file encoded with this example
+// versus one encoded with the `simple_encoder` example.

+// Two Pass Encoder
+// ================
+//
+// This is an example of a two pass encoder loop. It takes an input file in
+// YV12 format, passes it through the encoder twice, and writes the compressed
+// frames to disk in IVF format. It builds upon the simple_encoder example.
+//
+// Twopass Variables
+// -----------------
+// Twopass mode needs to track the current pass number and the buffer of
+// statistics packets.
+//
+// Updating The Configuration
+// ---------------------------------
+// In two pass mode, the configuration has to be updated on each pass. The
+// statistics buffer is passed on the last pass.
+//
+// Encoding A Frame
+// ----------------
+// Encoding a frame in two pass mode is identical to the simple encoder
+// example. To increase the quality while sacrificing encoding speed,
+// VPX_DL_BEST_QUALITY can be used in place of VPX_DL_GOOD_QUALITY.
+//
+// Processing Statistics Packets
+// -----------------------------
+// Each packet of type `VPX_CODEC_CX_FRAME_PKT` contains the encoded data
+// for this frame. We write a IVF frame header, followed by the raw data.
+//
+//
+// Pass Progress Reporting
+// -----------------------------
+// It's sometimes helpful to see when each pass completes.
+//
+//
+// Clean-up
+// -----------------------------
+// Destruction of the encoder instance must be done on each pass. The
+// raw image should be destroyed at the end as usual.

+// VP8 Set Reference Frame
+// =======================
+//
+// This is an example demonstrating how to overwrite the VP8 encoder's
+// internal reference frame. In the sample we set the last frame to the
+// current frame. If this is done at a cut scene it will avoid a keyframe.
+// This technique could be used to bounce between two cameras.
+//
+// Note that the decoder would also have to set the reference frame to the
+// same value on the same frame, or the video will become corrupt.
+//
+// Usage
+// -----
+// This example adds a single argument to the `simple_encoder` example,
+// which specifies the frame number to update the reference frame on.
+// The parameter is parsed as follows:
+//
+//
+// Extra Variables
+// ---------------
+// This example maintains the frame number passed on the command line
+// in the `update_frame_num` variable.
+//
+//
+// Configuration
+// -------------
+//
+// The reference frame is updated on the frame specified on the command
+// line.
+//
+// Observing The Effects
+// ---------------------
+// Use the `simple_encoder` example to encode a sample with a cut scene.
+// Determine the frame number of the cut scene by looking for a generated
+// key-frame (indicated by a 'K'). Supply that frame number as an argument
+// to this example, and observe that no key-frame is generated.

+// VP9 Set Reference Frame
+// ============================
+//
+// This is an example demonstrating how to overwrite the VP9 encoder's
+// internal reference frame. In the sample we set the last frame to the
+// current frame. This technique could be used to bounce between two cameras.
+//
+// The decoder would also have to set the reference frame to the same value
+// on the same frame, or the video will become corrupt. The 'test_decode'
+// variable is set to 1 in this example that tests if the encoder and decoder
+// results are matching.
+//
+// Usage
+// -----
+// This example encodes a raw video. And the last argument passed in specifies
+// the frame number to update the reference frame on. For example, run
+// examples/vp9cx_set_ref 352 288 in.yuv out.ivf 4 30
+// The parameter is parsed as follows:
+//
+//
+// Extra Variables
+// ---------------
+// This example maintains the frame number passed on the command line
+// in the `update_frame_num` variable.
+//
+//
+// Configuration
+// -------------
+//
+// The reference frame is updated on the frame specified on the command
+// line.
+//
+// Observing The Effects
+// ---------------------
+// The encoder and decoder results should be matching when the same reference
+// frame setting operation is done in both encoder and decoder. Otherwise,
+// the encoder/decoder mismatch would be seen.

+
+ * Create a directory in parallel to libvpx and change directory
+   $mkdir vpx_dec_fuzzer
+   $cd vpx_dec_fuzzer/
+
+ * Enable sanitizers (Supported: address integer memory thread undefined)
+   $source ../libvpx/tools/set_analyzer_env.sh address
+
+ * Configure libvpx.
+ * Note --size-limit and VPX_MAX_ALLOCABLE_MEMORY are defined to avoid
+ * Out of memory errors when running generated fuzzer binary

+/*!\page rfc2119 RFC2119 Keywords
+
+      The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL
+      NOT", "SHOULD", "SHOULD NOT", "RECOMMENDED",  "MAY", and
+      "OPTIONAL" in this document are to be interpreted as described in
+      <a href="http://www.ietf.org/rfc/rfc2119.txt">RFC 2119.</a>
+
+Specifically, the following definitions are used:
+
+\section MUST
+\anchor REQUIRED
+\anchor SHALL
+   This word, or the terms "REQUIRED" or "SHALL", mean that the
+   definition is an absolute requirement of the specification.
+
+\section MUSTNOT MUST NOT
+\anchor SHALLNOT
+   This phrase, or the phrase "SHALL NOT", mean that the
+   definition is an absolute prohibition of the specification.
+
+\section SHOULD
+\anchor RECOMMENDED
+   This word, or the adjective "RECOMMENDED", mean that there
+   may exist valid reasons in particular circumstances to ignore a
+   particular item, but the full implications must be understood and
+   carefully weighed before choosing a different course.
+
+\section SHOULDNOT SHOULD NOT
+\anchor NOTRECOMMENDED
+   This phrase, or the phrase "NOT RECOMMENDED" mean that
+   there may exist valid reasons in particular circumstances when the
+   particular behavior is acceptable or even useful, but the full
+   implications should be understood and the case carefully weighed
+   before implementing any behavior described with this label.
+
+\section MAY
+\anchor OPTIONAL
+   This word, or the adjective "OPTIONAL", mean that an item is
+   truly optional.  One vendor may choose to include the item because a
+   particular marketplace requires it or because the vendor feels that
+   it enhances the product while another vendor may omit the same item.
+   An implementation which does not include a particular option \ref MUST be
+   prepared to interoperate with another implementation which does
+   include the option, though perhaps with reduced functionality. In the
+   same vein an implementation which does include a particular option
+   \ref MUST be prepared to interoperate with another implementation which
+   does not include the option (except, of course, for the feature the
+   option provides.)

+ * Equivalent code is available from RSA Data Security, Inc.
+ * This code has been tested against that, and is equivalent,

+ * To compute the message digest of a chunk of bytes, declare an

+ * needed on buffers full of bytes, and then call MD5Final, which
+ * will fill a supplied 16-byte array with the digest.
+ *
+ * Changed so as no longer to depend on Colin Plumb's `usual.h' header
+ * definitions
+ *  - Ian Jackson <ian@chiark.greenend.org.uk>.

+Android.mk will build vpx unittests on android.
+1) Configure libvpx from the parent directory:
+./libvpx/configure --target=armv7-android-gcc --enable-external-build \
+  --enable-postproc --disable-install-srcs --enable-multi-res-encoding \
+  --enable-temporal-denoising --disable-unit-tests --disable-install-docs \
+  --disable-examples --disable-runtime-cpu-detect
+
+2) From the parent directory, invoke ndk-build:
+NDK_PROJECT_PATH=. ndk-build APP_BUILD_SCRIPT=./libvpx/test/android/Android.mk \
+  APP_ABI=armeabi-v7a APP_PLATFORM=android-18 APP_OPTIM=release \
+  APP_STL=c++_static
+
+Note: Both adb and ndk-build are available at:
+  https://developer.android.com/studio#downloads
+  https://developer.android.com/ndk/downloads
+
+3) Run get_files.py to download the test files:
+python get_files.py -i /path/to/test-data.sha1 -o /path/to/put/files \
+  -u http://downloads.webmproject.org/test_data/libvpx
+
+4) Transfer files to device using adb. Ensure you have proper permissions for
+the target
+
+adb push /path/to/test_files /data/local/tmp
+adb push /path/to/built_libs /data/local/tmp
+
+NOTE: Built_libs defaults to parent_dir/libs/armeabi-v7a
+
+5) Run tests:
+adb shell
+(on device)
+cd /data/local/tmp
+LD_LIBRARY_PATH=. ./vpx_test

+### Generic Build Instructions
+
+#### Setup
+
+To build Google Test and your tests that use it, you need to tell your build
+system where to find its headers and source files. The exact way to do it
+depends on which build system you use, and is usually straightforward.
+
+### Build with CMake
+
+Google Test comes with a CMake build script
+([CMakeLists.txt](https://github.com/google/googletest/blob/master/CMakeLists.txt))
+that can be used on a wide range of platforms ("C" stands for cross-platform.).
+If you don't have CMake installed already, you can download it for free from
+<http://www.cmake.org/>.
+
+CMake works by generating native makefiles or build projects that can be used in
+the compiler environment of your choice. You can either build Google Test as a
+standalone project or it can be incorporated into an existing CMake build for
+another project.
+
+#### Standalone CMake Project
+
+When building Google Test as a standalone project, the typical workflow starts
+with:
+
+    mkdir mybuild       # Create a directory to hold the build output.
+    cd mybuild
+    cmake ${GTEST_DIR}  # Generate native build scripts.
+
+If you want to build Google Test's samples, you should replace the last command
+with
+
+    cmake -Dgtest_build_samples=ON ${GTEST_DIR}
+
+If you are on a \*nix system, you should now see a Makefile in the current
+directory. Just type 'make' to build gtest.
+
+If you use Windows and have Visual Studio installed, a `gtest.sln` file and
+several `.vcproj` files will be created. You can then build them using Visual
+Studio.
+
+On Mac OS X with Xcode installed, a `.xcodeproj` file will be generated.
+
+#### Incorporating Into An Existing CMake Project
+
+If you want to use gtest in a project which already uses CMake, then a more
+robust and flexible approach is to build gtest as part of that project directly.
+This is done by making the GoogleTest source code available to the main build
+and adding it using CMake's `add_subdirectory()` command. This has the
+significant advantage that the same compiler and linker settings are used
+between gtest and the rest of your project, so issues associated with using
+incompatible libraries (eg debug/release), etc. are avoided. This is
+particularly useful on Windows. Making GoogleTest's source code available to the
+main build can be done a few different ways:
+
+*   Download the GoogleTest source code manually and place it at a known
+    location. This is the least flexible approach and can make it more difficult
+    to use with continuous integration systems, etc.
+*   Embed the GoogleTest source code as a direct copy in the main project's
+    source tree. This is often the simplest approach, but is also the hardest to
+    keep up to date. Some organizations may not permit this method.
+*   Add GoogleTest as a git submodule or equivalent. This may not always be
+    possible or appropriate. Git submodules, for example, have their own set of
+    advantages and drawbacks.
+*   Use CMake to download GoogleTest as part of the build's configure step. This
+    is just a little more complex, but doesn't have the limitations of the other
+    methods.
+
+The last of the above methods is implemented with a small piece of CMake code in
+a separate file (e.g. `CMakeLists.txt.in`) which is copied to the build area and
+then invoked as a sub-build _during the CMake stage_. That directory is then
+pulled into the main build with `add_subdirectory()`. For example:
+
+New file `CMakeLists.txt.in`:
+
+```cmake
+cmake_minimum_required(VERSION 2.8.2)
+
+project(googletest-download NONE)
+
+include(ExternalProject)
+ExternalProject_Add(googletest
+  GIT_REPOSITORY    https://github.com/google/googletest.git
+  GIT_TAG           master
+  SOURCE_DIR        "${CMAKE_CURRENT_BINARY_DIR}/googletest-src"
+  BINARY_DIR        "${CMAKE_CURRENT_BINARY_DIR}/googletest-build"
+  CONFIGURE_COMMAND ""
+  BUILD_COMMAND     ""
+  INSTALL_COMMAND   ""
+  TEST_COMMAND      ""
+)
+```
+
+Existing build's `CMakeLists.txt`:
+
+```cmake
+# Download and unpack googletest at configure time
+configure_file(CMakeLists.txt.in googletest-download/CMakeLists.txt)
+execute_process(COMMAND ${CMAKE_COMMAND} -G "${CMAKE_GENERATOR}" .
+  RESULT_VARIABLE result
+  WORKING_DIRECTORY ${CMAKE_CURRENT_BINARY_DIR}/googletest-download )
+if(result)
+  message(FATAL_ERROR "CMake step for googletest failed: ${result}")
+endif()
+execute_process(COMMAND ${CMAKE_COMMAND} --build .
+  RESULT_VARIABLE result
+  WORKING_DIRECTORY ${CMAKE_CURRENT_BINARY_DIR}/googletest-download )
+if(result)
+  message(FATAL_ERROR "Build step for googletest failed: ${result}")
+endif()
+
+# Prevent overriding the parent project's compiler/linker
+# settings on Windows
+set(gtest_force_shared_crt ON CACHE BOOL "" FORCE)
+
+# Add googletest directly to our build. This defines
+# the gtest and gtest_main targets.
+add_subdirectory(${CMAKE_CURRENT_BINARY_DIR}/googletest-src
+                 ${CMAKE_CURRENT_BINARY_DIR}/googletest-build
+                 EXCLUDE_FROM_ALL)
+
+# The gtest/gtest_main targets carry header search path
+# dependencies automatically when using CMake 2.8.11 or
+# later. Otherwise we have to add them here ourselves.
+if (CMAKE_VERSION VERSION_LESS 2.8.11)
+  include_directories("${gtest_SOURCE_DIR}/include")
+endif()
+
+# Now simply link against gtest or gtest_main as needed. Eg
+add_executable(example example.cpp)
+target_link_libraries(example gtest_main)
+add_test(NAME example_test COMMAND example)
+```
+
+Note that this approach requires CMake 2.8.2 or later due to its use of the
+`ExternalProject_Add()` command. The above technique is discussed in more detail
+in [this separate article](http://crascit.com/2015/07/25/cmake-gtest/) which
+also contains a link to a fully generalized implementation of the technique.
+
+##### Visual Studio Dynamic vs Static Runtimes
+
+By default, new Visual Studio projects link the C runtimes dynamically but
+Google Test links them statically. This will generate an error that looks
+something like the following: gtest.lib(gtest-all.obj) : error LNK2038: mismatch
+detected for 'RuntimeLibrary': value 'MTd_StaticDebug' doesn't match value
+'MDd_DynamicDebug' in main.obj
+
+Google Test already has a CMake option for this: `gtest_force_shared_crt`
+
+Enabling this option will make gtest link the runtimes dynamically too, and
+match the project in which it is included.
+
+#### C++ Standard Version
+
+An environment that supports C++11 is required in order to successfully build
+Google Test. One way to ensure this is to specify the standard in the top-level
+project, for example by using the `set(CMAKE_CXX_STANDARD 11)` command. If this
+is not feasible, for example in a C project using Google Test for validation,
+then it can be specified by adding it to the options for cmake via the
+`DCMAKE_CXX_FLAGS` option.
+
+### Tweaking Google Test
+
+Google Test can be used in diverse environments. The default configuration may
+not work (or may not work well) out of the box in some environments. However,
+you can easily tweak Google Test by defining control macros on the compiler
+command line. Generally, these macros are named like `GTEST_XYZ` and you define
+them to either 1 or 0 to enable or disable a certain feature.
+
+We list the most frequently used macros below. For a complete list, see file
+[include/gtest/internal/gtest-port.h](https://github.com/google/googletest/blob/master/googletest/include/gtest/internal/gtest-port.h).
+
+### Multi-threaded Tests
+
+Google Test is thread-safe where the pthread library is available. After
+`#include "gtest/gtest.h"`, you can check the
+`GTEST_IS_THREADSAFE` macro to see whether this is the case (yes if the macro is
+`#defined` to 1, no if it's undefined.).
+
+If Google Test doesn't correctly detect whether pthread is available in your
+environment, you can force it with
+
+    -DGTEST_HAS_PTHREAD=1
+
+or
+
+    -DGTEST_HAS_PTHREAD=0
+
+When Google Test uses pthread, you may need to add flags to your compiler and/or
+linker to select the pthread library, or you'll get link errors. If you use the
+CMake script or the deprecated Autotools script, this is taken care of for you.
+If you use your own build script, you'll need to read your compiler and linker's
+manual to figure out what flags to add.
+
+### As a Shared Library (DLL)
+
+Google Test is compact, so most users can build and link it as a static library
+for the simplicity. You can choose to use Google Test as a shared library (known
+as a DLL on Windows) if you prefer.
+
+To compile *gtest* as a shared library, add
+
+    -DGTEST_CREATE_SHARED_LIBRARY=1
+
+to the compiler flags. You'll also need to tell the linker to produce a shared
+library instead - consult your linker's manual for how to do it.
+
+To compile your *tests* that use the gtest shared library, add
+
+    -DGTEST_LINKED_AS_SHARED_LIBRARY=1
+
+to the compiler flags.
+
+Note: while the above steps aren't technically necessary today when using some
+compilers (e.g. GCC), they may become necessary in the future, if we decide to
+improve the speed of loading the library (see
+<http://gcc.gnu.org/wiki/Visibility> for details). Therefore you are recommended
+to always add the above flags when using Google Test as a shared library.
+Otherwise a future release of Google Test may break your build script.
+
+### Avoiding Macro Name Clashes
+
+In C++, macros don't obey namespaces. Therefore two libraries that both define a
+macro of the same name will clash if you `#include` both definitions. In case a
+Google Test macro clashes with another library, you can force Google Test to
+rename its macro to avoid the conflict.
+
+Specifically, if both Google Test and some other code define macro FOO, you can
+add
+
+    -DGTEST_DONT_DEFINE_FOO=1
+
+to the compiler flags to tell Google Test to change the macro's name from `FOO`
+to `GTEST_FOO`. Currently `FOO` can be `FAIL`, `SUCCEED`, or `TEST`. For
+example, with `-DGTEST_DONT_DEFINE_TEST=1`, you'll need to write
+
+    GTEST_TEST(SomeTest, DoesThis) { ... }
+
+instead of
+
+    TEST(SomeTest, DoesThis) { ... }
+
+in order to define a test.

+
+// Here's what happens when an ASSERT_DEATH* or EXPECT_DEATH* is
+// executed:
+//
+//   1. It generates a warning if there is more than one active
+//   thread.  This is because it's safe to fork() or clone() only
+//   when there is a single thread.
+//
+//   2. The parent process clone()s a sub-process and runs the death
+//   test in it; the sub-process exits with code 0 at the end of the
+//   death test, if it hasn't exited already.
+//
+//   3. The parent process waits for the sub-process to terminate.
+//
+//   4. The parent process checks the exit code and error message of
+//   the sub-process.
+//
+// Examples:
+//
+//   ASSERT_DEATH(server.SendMessage(56, "Hello"), "Invalid port number");
+//   for (int i = 0; i < 5; i++) {
+//     EXPECT_DEATH(server.ProcessRequest(i),
+//                  "Invalid request .* in ProcessRequest()")
+//                  << "Failed to die on request " << i;
+//   }
+//
+//   ASSERT_EXIT(server.ExitNow(), ::testing::ExitedWithCode(0), "Exiting");
+//
+//   bool KilledBySIGHUP(int exit_code) {
+//     return WIFSIGNALED(exit_code) && WTERMSIG(exit_code) == SIGHUP;
+//   }
+//
+//   ASSERT_EXIT(client.HangUpServer(), KilledBySIGHUP, "Hanging up!");
+//
+// On the regular expressions used in death tests:
+//
+//   GOOGLETEST_CM0005 DO NOT DELETE
+//   On POSIX-compliant systems (*nix), we use the <regex.h> library,
+//   which uses the POSIX extended regex syntax.
+//
+//   On other platforms (e.g. Windows or Mac), we only support a simple regex
+//   syntax implemented as part of Google Test.  This limited
+//   implementation should be enough most of the time when writing
+//   death tests; though it lacks many features you can find in PCRE
+//   or POSIX extended regex syntax.  For example, we don't support
+//   union ("x|y"), grouping ("(xy)"), brackets ("[xy]"), and
+//   repetition count ("x{5,7}"), among others.
+//
+//   Below is the syntax that we do support.  We chose it to be a
+//   subset of both PCRE and POSIX extended regex, so it's easy to
+//   learn wherever you come from.  In the following: 'A' denotes a
+//   literal character, period (.), or a single \\ escape sequence;
+//   'x' and 'y' denote regular expressions; 'm' and 'n' are for
+//   natural numbers.
+//
+//     c     matches any literal character c
+//     \\d   matches any decimal digit
+//     \\D   matches any character that's not a decimal digit
+//     \\f   matches \f
+//     \\n   matches \n
+//     \\r   matches \r
+//     \\s   matches any ASCII whitespace, including \n
+//     \\S   matches any character that's not a whitespace
+//     \\t   matches \t
+//     \\v   matches \v
+//     \\w   matches any letter, _, or decimal digit
+//     \\W   matches any character that \\w doesn't match
+//     \\c   matches any literal character c, which must be a punctuation
+//     .     matches any single character except \n
+//     A?    matches 0 or 1 occurrences of A
+//     A*    matches 0 or many occurrences of A
+//     A+    matches 1 or many occurrences of A
+//     ^     matches the beginning of a string (not that of each line)
+//     $     matches the end of a string (not that of each line)
+//     xy    matches x followed by y
+//
+//   If you accidentally use PCRE or POSIX extended regex features
+//   not implemented by us, you will get a run-time failure.  In that
+//   case, please try to rewrite your regular expression within the
+//   above syntax.
+//
+//   This implementation is *not* meant to be as highly tuned or robust
+//   as a compiled regex library, but should perform well enough for a
+//   death test, which already incurs significant overhead by launching
+//   a child process.
+//
+// Known caveats:
+//
+//   A "threadsafe" style death test obtains the path to the test
+//   program from argv[0] and re-executes it in the sub-process.  For
+//   simplicity, the current implementation doesn't search the PATH
+//   when launching the sub-process.  This means that the user must
+//   invoke the test program via a path that contains at least one
+//   path separator (e.g. path/to/foo_test and
+//   /absolute/path/to/bar_test are fine, but foo_test is not).  This
+//   is rarely a problem as people usually don't put the test binary
+//   directory in PATH.

+//
+// Parameters:

+//                parameter if and only if EXPECT_DEATH compiles with it.
+//   regex     -  A regex that a macro such as EXPECT_DEATH would use to test
+//                the output of statement.  This parameter has to be
+//                compiled but not evaluated by this macro, to ensure that
+//                this macro only accepts expressions that a macro such as
+//                EXPECT_DEATH would accept.
+//   terminator - Must be an empty statement for EXPECT_DEATH_IF_SUPPORTED
+//                and a return statement for ASSERT_DEATH_IF_SUPPORTED.
+//                This ensures that ASSERT_DEATH_IF_SUPPORTED will not

+//
+//  The branch that has an always false condition is used to ensure that

+// Value-parameterized tests allow you to test your code with different
+// parameters without writing multiple copies of the same test.
+//
+// Here is how you use value-parameterized tests:
+
+#if 0
+
+// To write value-parameterized tests, first you should define a fixture
+// class. It is usually derived from testing::TestWithParam<T> (see below for
+// another inheritance scheme that's sometimes useful in more complicated
+// class hierarchies), where the type of your parameter values.
+// TestWithParam<T> is itself derived from testing::Test. T can be any
+// copyable type. If it's a raw pointer, you are responsible for managing the
+// lifespan of the pointed values.
+
+class FooTest : public ::testing::TestWithParam<const char*> {
+  // You can implement all the usual class fixture members here.
+};
+
+// Then, use the TEST_P macro to define as many parameterized tests
+// for this fixture as you want. The _P suffix is for "parameterized"
+// or "pattern", whichever you prefer to think.
+
+TEST_P(FooTest, DoesBlah) {
+  // Inside a test, access the test parameter with the GetParam() method
+  // of the TestWithParam<T> class:
+  EXPECT_TRUE(foo.Blah(GetParam()));
+  ...
+}
+
+TEST_P(FooTest, HasBlahBlah) {
+  ...
+}
+
+// Finally, you can use INSTANTIATE_TEST_SUITE_P to instantiate the test
+// case with any set of parameters you want. Google Test defines a number
+// of functions for generating test parameters. They return what we call
+// (surprise!) parameter generators. Here is a summary of them, which
+// are all in the testing namespace:
+//
+//
+//  Range(begin, end [, step]) - Yields values {begin, begin+step,
+//                               begin+step+step, ...}. The values do not
+//                               include end. step defaults to 1.
+//  Values(v1, v2, ..., vN)    - Yields values {v1, v2, ..., vN}.
+//  ValuesIn(container)        - Yields values from a C-style array, an STL
+//  ValuesIn(begin,end)          container, or an iterator range [begin, end).
+//  Bool()                     - Yields sequence {false, true}.
+//  Combine(g1, g2, ..., gN)   - Yields all combinations (the Cartesian product
+//                               for the math savvy) of the values generated
+//                               by the N generators.
+//
+// For more details, see comments at the definitions of these functions below
+// in this file.
+//
+// The following statement will instantiate tests from the FooTest test suite
+// each with parameter values "meeny", "miny", and "moe".
+

+
+// To distinguish different instances of the pattern, (yes, you
+// can instantiate it more than once) the first argument to the
+// INSTANTIATE_TEST_SUITE_P macro is a prefix that will be added to the
+// actual test suite name. Remember to pick unique prefixes for different
+// instantiations. The tests from the instantiation above will have
+// these names:

+//    * InstantiationName/FooTest.HasBlahBlah/1 for "miny"
+//    * InstantiationName/FooTest.HasBlahBlah/2 for "moe"
+//
+// You can use these names in --gtest_filter.

+//    * AnotherInstantiationName/FooTest.HasBlahBlah/0 for "cat"
+//    * AnotherInstantiationName/FooTest.HasBlahBlah/1 for "dog"
+//
+// Please note that INSTANTIATE_TEST_SUITE_P will instantiate all tests
+// in the given test suite, whether their definitions come before or
+// AFTER the INSTANTIATE_TEST_SUITE_P statement.
+//
+// Please also note that generator expressions (including parameters to the
+// generators) are evaluated in InitGoogleTest(), after main() has started.
+// This allows the user on one hand, to adjust generator parameters in order
+// to dynamically determine a set of tests to run and on the other hand,
+// give the user a chance to inspect the generated tests with Google Test
+// reflection API before RUN_ALL_TESTS() is executed.
+//
+// You can see samples/sample7_unittest.cc and samples/sample8_unittest.cc
+// for more examples.
+//
+// In the future, we plan to publish the API for defining new parameter
+// generators. But for now this interface remains part of the internal
+// implementation and is subject to change.
+//
+//
+// A parameterized test fixture must be derived from testing::Test and from
+// testing::WithParamInterface<T>, where T is the type of the parameter
+// values. Inheriting from TestWithParam<T> satisfies that requirement because
+// TestWithParam<T> inherits from both Test and WithParamInterface. In more
+// complicated hierarchies, however, it is occasionally useful to inherit
+// separately from Test and WithParamInterface. For example:
+
+class BaseTest : public ::testing::Test {
+  // You can inherit all the usual members for a non-parameterized test
+  // fixture here.
+};
+
+class DerivedTest : public BaseTest, public ::testing::WithParamInterface<int> {

+// This file implements a universal value printer that can print a
+// value of any type T:
+//
+//   void ::testing::internal::UniversalPrinter<T>::Print(value, ostream_ptr);
+//
+// A user can teach this function how to print a class type T by
+// defining either operator<<() or PrintTo() in the namespace that
+// defines T.  More specifically, the FIRST defined function in the
+// following list will be used (assuming T is defined in namespace
+// foo):
+//
+//   1. foo::PrintTo(const T&, ostream*)
+//   2. operator<<(ostream&, const T&) defined in either foo or the
+//      global namespace.
+//
+// However if T is an STL-style container then it is printed element-wise
+// unless foo::PrintTo(const T&, ostream*) is defined. Note that
+// operator<<() is ignored for container types.
+//
+// If none of the above is defined, it will print the debug string of
+// the value if it is a protocol buffer, or print the raw bytes in the
+// value otherwise.
+//
+// To aid debugging: when T is a reference type, the address of the
+// value is also printed; when T is a (const) char pointer, both the
+// pointer value and the NUL-terminated string it points to are
+// printed.
+//
+// We also provide some convenient wrappers:
+//
+//   // Prints a value to a string.  For a (const or not) char
+//   // pointer, the NUL-terminated string (but not the pointer) is
+//   // printed.
+//   std::string ::testing::PrintToString(const T& value);
+//
+//   // Prints a value tersely: for a reference type, the referenced
+//   // value (but not the address) is printed; for a (const or not) char
+//   // pointer, the NUL-terminated string (but not the pointer) is
+//   // printed.
+//   void ::testing::internal::UniversalTersePrint(const T& value, ostream*);
+//
+//   // Prints value using the type inferred by the compiler.  The difference
+//   // from UniversalTersePrint() is that this function prints both the
+//   // pointer and the NUL-terminated string for a (const or not) char pointer.
+//   void ::testing::internal::UniversalPrint(const T& value, ostream*);
+//
+//   // Prints the fields of a tuple tersely to a string vector, one
+//   // element for each field. Tuple support must be enabled in
+//   // gtest-port.h.
+//   std::vector<string> UniversalTersePrintTupleFieldsToStrings(
+//       const Tuple& value);
+//
+// Known limitation:
+//
+// The print primitives print the elements of an STL-style container
+// using the compiler-inferred type of *iter where iter is a
+// const_iterator of the container.  When const_iterator is an input
+// iterator but not a forward iterator, this inferred type may not
+// match value_type, and the print output may be incorrect.  In
+// practice, this is rarely a problem as for most containers
+// const_iterator is a forward iterator.  We'll fix this if there's an
+// actual need for it.  Note that this fix cannot rely on value_type
+// being defined as many user-defined container types don't have
+// value_type.

+// A class for indicating whether an assertion was successful.  When
+// the assertion wasn't successful, the AssertionResult object
+// remembers a non-empty message that describes how it failed.
+//
+// To create an instance of this class, use one of the factory functions
+// (AssertionSuccess() and AssertionFailure()).
+//
+// This class is useful for two purposes:
+//   1. Defining predicate functions to be used with Boolean test assertions
+//      EXPECT_TRUE/EXPECT_FALSE and their ASSERT_ counterparts
+//   2. Defining predicate-format functions to be
+//      used with predicate assertions (ASSERT_PRED_FORMAT*, etc).
+//
+// For example, if you define IsEven predicate:
+//
+//   testing::AssertionResult IsEven(int n) {
+//     if ((n % 2) == 0)
+//       return testing::AssertionSuccess();
+//     else
+//       return testing::AssertionFailure() << n << " is odd";
+//   }
+//
+// Then the failed expectation EXPECT_TRUE(IsEven(Fib(5)))
+// will print the message
+//
+//   Value of: IsEven(Fib(5))
+//     Actual: false (5 is odd)
+//   Expected: true
+//
+// instead of a more opaque
+//
+//   Value of: IsEven(Fib(5))
+//     Actual: false
+//   Expected: true
+//
+// in case IsEven is a simple Boolean predicate.
+//
+// If you expect your predicate to be reused and want to support informative
+// messages in EXPECT_FALSE and ASSERT_FALSE (negative assertions show up
+// about half as often as positive ones in our tests), supply messages for
+// both success and failure cases:
+//
+//   testing::AssertionResult IsEven(int n) {
+//     if ((n % 2) == 0)
+//       return testing::AssertionSuccess() << n << " is even";
+//     else
+//       return testing::AssertionFailure() << n << " is odd";
+//   }
+//
+// Then a statement EXPECT_FALSE(IsEven(Fib(6))) will print
+//
+//   Value of: IsEven(Fib(6))
+//     Actual: true (8 is even)
+//   Expected: false
+//
+// NB: Predicates that support negative Boolean assertions have reduced
+// performance in positive ones so be careful not to use them in tests
+// that have lots (tens of thousands) of positive Boolean assertions.
+//
+// To use this class with EXPECT_PRED_FORMAT assertions such as:
+//
+//   // Verifies that Foo() returns an even number.
+//   EXPECT_PRED_FORMAT1(IsEven, Foo());
+//
+// you need to define:
+//
+//   testing::AssertionResult IsEven(const char* expr, int n) {
+//     if ((n % 2) == 0)
+//       return testing::AssertionSuccess();
+//     else
+//       return testing::AssertionFailure()
+//         << "Expected: " << expr << " is even\n  Actual: it's " << n;
+//   }
+//
+// If Foo() returns 5, you will see the following message:
+//
+//   Expected: Foo() is even
+//     Actual: it's 5
+//

+//   with two C strings, you are testing how their locations in memory
+//   are related, not how their content is related.  To compare two C
+//   strings by content, use {ASSERT|EXPECT}_STR*().
+//
+//   3. {ASSERT|EXPECT}_EQ(v1, v2) is preferred to
+//   {ASSERT|EXPECT}_TRUE(v1 == v2), as the former tells you
+//   what the actual value is when it fails, and similarly for the
+//   other comparisons.
+//
+//   4. Do not depend on the order in which {ASSERT|EXPECT}_??()
+//   evaluate their arguments, which is undefined.
+//
+//   5. These macros evaluate their arguments exactly once.
+//

+// Environment-describing macros
+// -----------------------------
+//
+// Google Test can be used in many different environments.  Macros in
+// this section tell Google Test what kind of environment it is being
+// used in, such that Google Test can provide environment-specific
+// features and implementations.
+//
+// Google Test tries to automatically detect the properties of its
+// environment, so users usually don't need to worry about these
+// macros.  However, the automatic detection is not perfect.
+// Sometimes it's necessary for a user to define some of the following
+// macros in the build script to override Google Test's decisions.
+//
+// If the user doesn't define a macro in the list, Google Test will
+// provide a default definition.  After this header is #included, all
+// macros in this list will be defined to either 1 or 0.
+//
+// Notes to maintainers:
+//   - Each macro here is a user-tweakable knob; do not grow the list
+//     lightly.
+//   - Use #if to key off these macros.  Don't use #ifdef or "#if
+//     defined(...)", which will not work as these macros are ALWAYS
+//     defined.
+//
+//   GTEST_HAS_CLONE          - Define it to 1/0 to indicate that clone(2)
+//                              is/isn't available.
+//   GTEST_HAS_EXCEPTIONS     - Define it to 1/0 to indicate that exceptions
+//                              are enabled.
+//   GTEST_HAS_POSIX_RE       - Define it to 1/0 to indicate that POSIX regular
+//                              expressions are/aren't available.
+//   GTEST_HAS_PTHREAD        - Define it to 1/0 to indicate that <pthread.h>
+//                              is/isn't available.
+//   GTEST_HAS_RTTI           - Define it to 1/0 to indicate that RTTI is/isn't
+//                              enabled.
+//   GTEST_HAS_STD_WSTRING    - Define it to 1/0 to indicate that
+//                              std::wstring does/doesn't work (Google Test can
+//                              be used where std::wstring is unavailable).
+//   GTEST_HAS_SEH            - Define it to 1/0 to indicate whether the
+//                              compiler supports Microsoft's "Structured
+//                              Exception Handling".
+//   GTEST_HAS_STREAM_REDIRECTION
+//                            - Define it to 1/0 to indicate whether the
+//                              platform supports I/O stream redirection using
+//                              dup() and dup2().
+//   GTEST_LINKED_AS_SHARED_LIBRARY
+//                            - Define to 1 when compiling tests that use
+//                              Google Test as a shared library (known as
+//                              DLL on Windows).
+//   GTEST_CREATE_SHARED_LIBRARY
+//                            - Define to 1 when compiling Google Test itself
+//                              as a shared library.
+//   GTEST_DEFAULT_DEATH_TEST_STYLE
+//                            - The default value of --gtest_death_test_style.
+//                              The legacy default has been "fast" in the open
+//                              source version since 2008. The recommended value
+//                              is "threadsafe", and can be set in
+//                              custom/gtest-port.h.
+
+// Platform-indicating macros
+// --------------------------
+//
+// Macros indicating the platform on which Google Test is being used
+// (a macro is defined to 1 if compiled on the given platform;
+// otherwise UNDEFINED -- it's never defined to 0.).  Google Test
+// defines these macros automatically.  Code outside Google Test MUST
+// NOT define them.
+//
+//   GTEST_OS_AIX      - IBM AIX

+// don't have access to other platforms, support for them may be less
+// stable.  If you notice any problems on your platform, please notify
+// googletestframework@googlegroups.com (patches for fixing them are
+// even more welcome!).
+//
+// It is possible that none of the GTEST_OS_* macros are defined.
+
+// Feature-indicating macros
+// -------------------------
+//
+// Macros indicating which Google Test features are available (a macro
+// is defined to 1 if the corresponding feature is supported;
+// otherwise UNDEFINED -- it's never defined to 0.).  Google Test
+// defines these macros automatically.  Code outside Google Test MUST
+// NOT define them.
+//
+// These macros are public so that portable tests can be written.
+// Such tests typically surround code using a feature with an #if
+// which controls that code.  For example:
+//
+// #if GTEST_HAS_DEATH_TEST
+//   EXPECT_DEATH(DoSomethingDeadly());
+// #endif
+//
+//   GTEST_HAS_DEATH_TEST   - death tests
+//   GTEST_HAS_TYPED_TEST   - typed tests
+//   GTEST_HAS_TYPED_TEST_P - type-parameterized tests
+//   GTEST_IS_THREADSAFE    - Google Test is thread-safe.
+//   GOOGLETEST_CM0007 DO NOT DELETE
+//   GTEST_USES_POSIX_RE    - enhanced POSIX regex is used. Do not confuse with
+//                            GTEST_HAS_POSIX_RE (see above) which users can
+//                            define themselves.
+//   GTEST_USES_SIMPLE_RE   - our own simple regex is used;
+//                            the above RE\b(s) are mutually exclusive.
+
+// Misc public macros
+// ------------------
+//
+//   GTEST_FLAG(flag_name)  - references the variable corresponding to
+//                            the given Google Test flag.
+
+// Internal utilities
+// ------------------
+//
+// The following macros and utilities are for Google Test's INTERNAL
+// use only.  Code outside Google Test MUST NOT USE THEM DIRECTLY.
+//
+// Macros for basic C++ coding:
+//   GTEST_AMBIGUOUS_ELSE_BLOCKER_ - for disabling a gcc warning.
+//   GTEST_ATTRIBUTE_UNUSED_  - declares that a class' instances or a

+//                                        suppressed (constant conditional).
+//   GTEST_INTENTIONAL_CONST_COND_POP_  - finish code section where MSVC C4127
+//                                        is suppressed.
+//   GTEST_INTERNAL_HAS_STRING_VIEW - for enabling Matcher<std::string_view> or
+//                                    Matcher<absl::string_view>
+//                                    specializations.
+//
+// Synchronization:

+//                    or a reduced regular exception syntax on other
+//                    platforms, including Windows.
+// Logging:
+//   GTEST_LOG_()   - logs messages at the specified severity level.
+//   LogToStderr()  - directs all log messages to stderr.
+//   FlushInfoLog() - flushes informational log messages.
+//
+// Stdout and stderr capturing:
+//   CaptureStdout()     - starts capturing stdout.
+//   GetCapturedStdout() - stops capturing stdout and returns the captured
+//                         string.
+//   CaptureStderr()     - starts capturing stderr.
+//   GetCapturedStderr() - stops capturing stderr and returns the captured
+//                         string.
+//
+// Integer types:
+//   TypeWithSize   - maps an integer to a int type.
+//   TimeInMillis   - integers of known sizes.

+//
+// Command-line utilities:
+//   GTEST_DECLARE_*()  - declares a flag.
+//   GTEST_DEFINE_*()   - defines a flag.

+//
+// A few implementation notes:  Like the Linux version, the Windows
+// implementation uses pipes for child-to-parent communication. But due to
+// the specifics of pipes on Windows, some extra steps are required:
+//
+// 1. The parent creates a communication pipe and stores handles to both
+//    ends of it.
+// 2. The parent starts the child and provides it with the information
+//    necessary to acquire the handle to the write end of the pipe.
+// 3. The child acquires the write end of the pipe and signals the parent
+//    using a Windows event.
+// 4. Now the parent can release the write end of the pipe on its side. If
+//    this is done before step 3, the object's reference count goes down to
+//    0 and it is destroyed, preventing the child from acquiring it. The
+//    parent now has to release it, or read operations on the read end of
+//    the pipe will not return when the child terminates.
+// 5. The parent reads child's output through the pipe (outcome code and
+//    any possible error messages) from the pipe, and its stderr and then
+//    determines whether to fail the test.
+//
+// Note: to distinguish Win32 API calls from the local method and function
+// calls, the former are explicitly resolved in the global namespace.

+Description:
+libyuv is an open source project that includes YUV conversion and scaling
+functionality.
+
+The optimized scaler in libyuv is used in the multiple resolution encoder
+example which down-samples the original input video (f.g. 1280x720) a number of
+times in order to encode multiple resolution bit streams.
+
+Local Modifications:
+Disable ARGBToRGB24Row_AVX512VBMI due to build failure on Mac.

+ARGBToAR30Row:
+
+Red Blue
+With the 8 bit value in the upper bits of a short, vpmulhuw by (1024+4) will
+produce a 10 bit value in the low 10 bits of each 16 bit value. This is whats
+wanted for the blue channel. The red needs to be shifted 4 left, so multiply by
+(1024+4)*16 for red.
+
+Alpha Green
+Alpha and Green are already in the high bits so vpand can zero out the other
+bits, keeping just 2 upper bits of alpha and 8 bit green. The same multiplier
+could be used for Green - (1024+4) putting the 10 bit green in the lsb.  Alpha
+would be a simple multiplier to shift it into position.  It wants a gap of 10
+above the green.  Green is 10 bits, so there are 6 bits in the low short.  4
+more are needed, so a multiplier of 4 gets the 2 bits into the upper 16 bits,
+and then a shift of 4 is a multiply of 16, so (4*16) = 64.  Then shift the
+result left 10 to position the A and G channels.

+Description:
+x264/libav's framework for x86 assembly. Contains a variety of macros and
+defines that help automatically allow assembly to work cross-platform.
+
+Local Modifications:
+Get configuration from vpx_config.asm.
+Prefix functions with vpx by default.
+Manage name mangling (prefixing with '_') manually because 'PREFIX' does not
+  exist in libvpx.
+Copy PIC 'GLOBAL' macros from x86_abi_support.asm
+Use .text instead of .rodata on macho to avoid broken tables in PIC mode.
+Use .text with no alignment for aout.
+Only use 'hidden' visibility with Chromium.
+Prefix ARCH_* with VPX_.

+
+; This is a header file for the x264ASM assembly language, which uses
+; NASM/YASM syntax combined with a large number of macros to provide easy
+; abstraction between different calling conventions (x86_32, win64, linux64).
+; It also has various other useful features to simplify writing the kind of
+; DSP functions that are most often used in x264.
+
+; Unlike the rest of x264, this file is available under an ISC license, as it
+; has significant usefulness outside of x264 and we want it to be available
+; to the largest audience possible.  Of course, if you modify it for your own
+; purposes to add a new feature, we strongly encourage contributing a patch
+; as this feature might be useful for others as well.  Send patches or ideas
+; to x264-devel@videolan.org .

+; Macros to eliminate most code duplication between x86_32 and x86_64:
+; Currently this works only for leaf functions which load all their arguments
+; into registers at the start, and make no other use of the stack. Luckily that
+; covers most of x264's asm.
+
+; PROLOGUE:
+; %1 = number of arguments. loads them from stack if needed.
+; %2 = number of registers used. pushes callee-saved regs if needed.
+; %3 = number of xmm registers used. pushes callee-saved xmm regs if needed.
+; %4 = (optional) stack size to be allocated. The stack will be aligned before
+;      allocating the specified stack size. If the required stack alignment is
+;      larger than the known stack alignment the stack will be manually aligned
+;      and an extra register will be allocated to hold the original stack
+;      pointer (to not invalidate r0m etc.). To prevent the use of an extra
+;      register as stack pointer, request a negative stack size.
+; %4+/%5+ = list of names to define to registers
+; PROLOGUE can also be invoked by adding the same options to cglobal
+
+; e.g.
+; cglobal foo, 2,3,7,0x40, dst, src, tmp
+; declares a function (foo) that automatically loads two arguments (dst and
+; src) into registers, uses one additional register (tmp) plus 7 vector
+; registers (m0-m6) and allocates 0x40 bytes of stack space.
+
+; TODO Some functions can use some args directly from the stack. If they're the
+; last args then you can just not declare them, but if they're in the middle
+; we need more flexible macro.
+
+; RET:
+; Pops anything that was pushed by PROLOGUE, and returns.
+
+; REP_RET:
+; Use this instead of RET if it's a branch target.
+
+; registers:
+; rN and rNq are the native-size register holding function argument N
+; rNd, rNw, rNb are dword, word, and byte size
+; rNh is the high 8 bits of the word size
+; rNm is the original location of arg N (a register or on the stack), dword
+; rNmp is native size

+up these problems -- the point is to educate.  It does also not
+attempt to find all problems, or to ensure that everything it does
+find is legitimately a problem.
+
+In particular, we can get very confused by /* and // inside strings!
+We do a small hack, which is to ignore //'s with "'s after them on the

+Syntax: cpplint.py [--verbose=#] [--output=vs7] [--filter=-x,+y,...]
+                   [--counting=total|toplevel|detailed] [--root=subdir]
+                   [--linelength=digits]
+        <file> [file] ...
+
+  The style guidelines this tries to follow are those in
+    http://google-styleguide.googlecode.com/svn/trunk/cppguide.xml
+
+  Every problem is given a confidence score from 1-5, with 5 meaning we are
+  certain of the problem, and 1 meaning it could be a legitimate construct.
+  This will miss some errors, and is not a substitute for a code review.
+
+  To suppress false-positive errors of a certain category, add a
+  'NOLINT(category)' comment to the line.  NOLINT or NOLINT(*)
+  suppresses errors of all categories on that line.
+
+  The files passed in will be linted; at least one file must be provided.
+  Default linted extensions are .cc, .cpp, .cu, .cuh and .h.  Change the
+  extensions with the --extensions flag.
+
+  Flags:
+
+    output=vs7
+      By default, the output is formatted to ease emacs parsing.  Visual Studio
+      compatible output (vs7) may also be used.  Other formats are unsupported.
+
+    verbose=#
+      Specify a number 0-5 to restrict errors to certain verbosity levels.
+
+    filter=-x,+y,...
+      Specify a comma-separated list of category-filters to apply: only
+      error messages whose category names pass the filters will be printed.
+      (Category names are printed with the message and look like
+      "[whitespace/indent]".)  Filters are evaluated left to right.
+      "-FOO" and "FOO" means "do not print categories that start with FOO".
+      "+FOO" means "do print categories that start with FOO".
+
+      Examples: --filter=-whitespace,+whitespace/braces
+                --filter=whitespace,runtime/printf,+runtime/printf_format
+                --filter=-,+build/include_what_you_use
+
+      To see a list of all the categories used in cpplint, pass no arg:
+         --filter=
+
+    counting=total|toplevel|detailed
+      The total number of errors found is always printed. If
+      'toplevel' is provided, then the count of errors in each of
+      the top-level categories like 'build' and 'whitespace' will
+      also be printed. If 'detailed' is provided, then a count
+      is provided for each category like 'build/class'.
+
+    root=subdir
+      The root directory used for deriving header guard CPP variable.
+      By default, the header guard CPP variable is calculated as the relative
+      path to the directory that contains .git, .hg, or .svn.  When this flag
+      is specified, the relative path is calculated from the specified
+      directory. If the specified directory does not exist, this flag is
+      ignored.
+
+      Examples:
+        Assuing that src/.git exists, the header guard CPP variables for
+        src/chrome/browser/ui/browser.h are:
+
+        No flag => CHROME_BROWSER_UI_BROWSER_H_
+        --root=chrome => BROWSER_UI_BROWSER_H_
+        --root=chrome/browser => UI_BROWSER_H_
+
+    linelength=digits
+      This is the allowed line length for the project. The default value is
+      80 characters.
+
+      Examples:
+        --linelength=120
+
+    extensions=extension,extension,...
+      The allowed file extensions that cpplint will check
+
+      Examples:
+        --extensions=hpp,cpp

+"""Wraps paragraphs of text, preserving manual formatting
+
+This is like fold(1), but has the special convention of not modifying lines
+that start with whitespace. This allows you to intersperse blocks with
+special formatting, like code blocks, with written prose. The prose will
+be wordwrapped, and the manual formatting will be preserved.
+
+ * This won't handle the case of a bulleted (or ordered) list specially, so
+   manual wrapping must be done.
+
+Occasionally it's useful to put something with explicit formatting that
+doesn't look at all like a block of text inline.
+
+  indicator = has_leading_whitespace(line);
+  if (indicator)
+    preserve_formatting(line);
+
+The intent is that this docstring would make it through the transform
+and still be legible and presented as it is in the source. If additional
+cases are handled, update this doc to describe the effect.

+/*!\page usage Usage
+
+    The vpx multi-format codec SDK provides a unified interface amongst its
+    supported codecs. This abstraction allows applications using this SDK to
+    easily support multiple video formats with minimal code duplication or
+    "special casing." This section describes the interface common to all codecs.
+    For codec-specific details, see the \ref codecs page.
+
+    The following sections are common to all codecs:
+    - \ref usage_types
+    - \ref usage_features
+    - \ref usage_init
+    - \ref usage_errors
+
+    For more information on decoder and encoder specific usage, see the
+    following pages:
+    \if decoder
+    \li \subpage usage_decode
+    \endif
+    \if encoder
+    \li \subpage usage_encode
+    \endif
+
+    \section usage_types Important Data Types
+    There are two important data structures to consider in this interface.
+
+    \subsection usage_ctxs Contexts
+    A context is a storage area allocated by the calling application that the
+    codec may write into to store details about a single instance of that codec.
+    Most of the context is implementation specific, and thus opaque to the
+    application. The context structure as seen by the application is of fixed
+    size, and thus can be allocated with automatic storage or dynamically
+    on the heap.
+
+    Most operations require an initialized codec context. Codec context
+    instances are codec specific. That is, the codec to be used for the encoded
+    video must be known at initialization time. See #vpx_codec_ctx_t for further
+    information.
+
+    \subsection usage_ifaces Interfaces
+    A codec interface is an opaque structure that controls how function calls
+    into the generic interface are dispatched to their codec-specific
+    implementations. Applications \ref MUSTNOT attempt to examine or override
+    this storage, as it contains internal implementation details likely to
+    change from release to release.
+
+    Each supported codec will expose an interface structure to the application
+    as an <code>extern</code> reference to a structure of the incomplete type
+    #vpx_codec_iface_t.
+
+    \section usage_features Features
+    Several "features" are defined that are optionally implemented by codec
+    algorithms. Indeed, the same algorithm may support different features on
+    different platforms. The purpose of defining these features is that when
+    they are implemented, they conform to a common interface. The features, or
+    capabilities, of an algorithm can be queried from it's interface by using
+    the vpx_codec_get_caps() method. Attempts to invoke features not supported
+    by an algorithm will generally result in #VPX_CODEC_INCAPABLE.
+
+    \if decoder
+    Currently defined decoder features include:
+    - \ref usage_cb
+    - \ref usage_postproc
+    \endif
+
+    \section usage_init Initialization
+    To initialize a codec instance, the address of the codec context
+    and interface structures are passed to an initialization function. Depending
+    on the \ref usage_features that the codec supports, the codec could be
+    initialized in different modes.
+
+    To prevent cases of confusion where the ABI of the library changes,
+    the ABI is versioned. The ABI version number must be passed at
+    initialization time to ensure the application is using a header file that
+    matches the library. The current ABI version number is stored in the
+    preprocessor macros #VPX_CODEC_ABI_VERSION, #VPX_ENCODER_ABI_VERSION, and
+    #VPX_DECODER_ABI_VERSION. For convenience, each initialization function has
+    a wrapper macro that inserts the correct version number. These macros are
+    named like the initialization methods, but without the _ver suffix.
+
+
+    The available initialization methods are:
+    \if encoder
+    \li #vpx_codec_enc_init (calls vpx_codec_enc_init_ver())
+    \li #vpx_codec_enc_init_multi (calls vpx_codec_enc_init_multi_ver())
+    \endif
+    \if decoder
+    \li #vpx_codec_dec_init (calls vpx_codec_dec_init_ver())
+    \endif
+
+
+    \section usage_errors Error Handling
+    Almost all codec functions return an error status of type #vpx_codec_err_t.
+    The semantics of how each error condition should be processed is clearly
+    defined in the definitions of each enumerated value. Error values can be
+    converted into ASCII strings with the vpx_codec_error() and
+    vpx_codec_err_to_string() methods. The difference between these two methods is
+    that vpx_codec_error() returns the error state from an initialized context,
+    whereas vpx_codec_err_to_string() can be used in cases where an error occurs
+    outside any context. The enumerated value returned from the last call can be
+    retrieved from the <code>err</code> member of the decoder context as well.
+    Finally, more detailed error information may be able to be obtained by using
+    the vpx_codec_error_detail() method. Not all errors produce detailed error
+    information.
+
+    In addition to error information, the codec library's build configuration
+    is available at runtime on some platforms. This information can be returned
+    by calling vpx_codec_build_config(), and is formatted as a base64 coded string
+    (comprised of characters in the set [a-z_a-Z0-9+/]). This information is not
+    useful to an application at runtime, but may be of use to vpx for support.
+
+
+    \section usage_deadline Deadline
+    Both the encoding and decoding functions have a <code>deadline</code>
+    parameter. This parameter indicates the amount of time, in microseconds
+    (us), that the application wants the codec to spend processing before
+    returning. This is a soft deadline -- that is, the semantics of the
+    requested operation take precedence over meeting the deadline. If, for
+    example, an application sets a <code>deadline</code> of 1000us, and the
+    frame takes 2000us to decode, the call to vpx_codec_decode() will return
+    after 2000us. In this case the deadline is not met, but the semantics of the
+    function are preserved. If, for the same frame, an application instead sets
+    a <code>deadline</code> of 5000us, the decoder will see that it has 3000us
+    remaining in its time slice when decoding completes. It could then choose to
+    run a set of \ref usage_postproc filters, and perhaps would return after
+    4000us (instead of the allocated 5000us). In this case the deadline is met,
+    and the semantics of the call are preserved, as before.
+
+    The special value <code>0</code> is reserved to represent an infinite
+    deadline. In this case, the codec will perform as much processing as
+    possible to yield the highest quality frame.
+
+    By convention, the value <code>1</code> is used to mean "return as fast as
+    possible."

+    decoder when decoded data becomes available. Decoders are not required to
+    support this feature, however. Like all \ref usage_features, support can be
+    determined by calling vpx_codec_get_caps(). Callbacks are available in both
+    frame-based and slice-based variants. Frame based callbacks conform to the
+    signature of #vpx_codec_put_frame_cb_fn_t and are invoked once the entire
+    frame has been decoded. Slice based callbacks conform to the signature of
+    #vpx_codec_put_slice_cb_fn_t and are invoked after a subsection of the frame
+    is decoded. For example, a slice callback could be issued for each
+    macroblock row. However, the number and size of slices to return is
+    implementation specific. Also, the image data passed in a slice callback is
+    not necessarily in the same memory segment as the data will be when it is
+    assembled into a full frame. For this reason, the application \ref MUST
+    examine the rectangles that describe what data is valid to access and what
+    data has been updated in this call. For all their additional complexity,
+    slice based decoding callbacks provide substantial speed gains to the
+    overall application in some cases, due to improved cache behavior.
+
+
+    \section usage_frame_iter Frame Iterator Based Decoding
+    If the codec does not support callback based decoding, or the application
+    chooses not to make use of that feature, decoded frames are made available
+    through the vpx_codec_get_frame() iterator. The application initializes the
+    iterator storage (of type #vpx_codec_iter_t) to NULL, then calls
+    vpx_codec_get_frame repeatedly until it returns NULL, indicating that all
+    images have been returned. This process may result in zero, one, or many
+    frames that are ready for display, depending on the codec.
+
+
+    \section usage_postproc Postprocessing
+    Postprocessing is a process that is applied after a frame is decoded to
+    enhance the image's appearance by removing artifacts introduced in the
+    compression process. It is not required to properly decode the frame, and
+    is generally done only when there is enough spare CPU time to execute
+    the required filters. Codecs may support a number of different
+    postprocessing filters, and the available filters may differ from platform
+    to platform. Embedded devices often do not have enough CPU to implement
+    postprocessing in software. The filter selection is generally handled
+    automatically by the codec, depending on the amount of time remaining before
+    hitting the user-specified \ref usage_deadline after decoding the frame.

+ *         2.   sqrt(2) * sin (pi/8)

+ * The filter function was modified to reduce the computational complexity.
+ *
+ * Step 1:
+ *  Instead of applying tap coefficients for each pixel, we calculated the
+ *  pixel adjustments vs. pixel diff value ahead of time.
+ *     adjustment = filtered_value - current_raw
+ *                = (filter_coefficient * diff + 128) >> 8
+ *  where
+ *     filter_coefficient = (255 << 8) / (256 + ((abs_diff * 330) >> 3));
+ *     filter_coefficient += filter_coefficient /
+ *                           (3 + motion_magnitude_adjustment);
+ *     filter_coefficient is clamped to 0 ~ 255.
+ *
+ * Step 2:
+ *  The adjustment vs. diff curve becomes flat very quick when diff increases.
+ *  This allowed us to use only several levels to approximate the curve without
+ *  changing the filtering algorithm too much.
+ *  The adjustments were further corrected by checking the motion magnitude.
+ *  The levels used are:
+ *      diff          level       adjustment w/o       adjustment w/
+ *                               motion correction    motion correction

+ * The filter function was modified to reduce the computational complexity.

+ * Instead of applying tap coefficients for each pixel, we calculated the
+ * pixel adjustments vs. pixel diff value ahead of time.
+ *     adjustment = filtered_value - current_raw
+ *                = (filter_coefficient * diff + 128) >> 8
+ * where
+ *     filter_coefficient = (255 << 8) / (256 + ((absdiff * 330) >> 3));
+ *     filter_coefficient += filter_coefficient /
+ *                           (3 + motion_magnitude_adjustment);
+ *     filter_coefficient is clamped to 0 ~ 255.
+ *
+ * Step 2:
+ * The adjustment vs. diff curve becomes flat very quick when diff increases.
+ * This allowed us to use only several levels to approximate the curve without
+ * changing the filtering algorithm too much.
+ * The adjustments were further corrected by checking the motion magnitude.

+ * 'cal_nmvsadcosts') are used to calculate cost lookup tables         *
+ * used by 'vp9_diamond_search_sad'. The C implementation of the       *
+ * function is generic, but the AVX intrinsics optimised version       *
+ * relies on the following properties of the computed tables:          *
+ * For cal_nmvjointsadcost:                                            *
+ *   - mvjointsadcost[1] == mvjointsadcost[2] == mvjointsadcost[3]     *
+ * For cal_nmvsadcosts:                                                *
+ *   - For all i: mvsadcost[0][i] == mvsadcost[1][i]                   *
+ *         (Equal costs for both components)                           *
+ *   - For all i: mvsadcost[0][i] == mvsadcost[0][-i]                  *
+ *         (Cost function is even)                                     *
+ * If these do not hold, then the AVX optimised version of the         *
+ * 'vp9_diamond_search_sad' function cannot be used as it is, in which *
+ * case you can revert to using the C function instead.                *

+// Division using multiplication and shifting. The C implementation does:
+// modifier *= 3;
+// modifier /= index;
+// where 'modifier' is a set of summed values and 'index' is the number of
+// summed values.
+//
+// This equation works out to (m * 3) / i which reduces to:
+// m * 3/4
+// m * 1/2
+// m * 1/3
+//
+// By pairing the multiply with a down shift by 16 (_mm_mulhi_epu16):
+// m * C / 65536
+// we can create a C to replicate the division.
+//
+// m * 49152 / 65536 = m * 3/4
+// m * 32758 / 65536 = m * 1/2
+// m * 21846 / 65536 = m * 0.3333
+//
+// These are loaded using an instruction expecting int16_t values but are used
+// with _mm_mulhi_epu16(), which treats them as unsigned.

+ * This file defines the private structures and data types that are only
+ * relevant to implementing an algorithm, as opposed to using it.
+ *
+ * To create a decoder algorithm class, an interface structure is put
+ * into the global namespace:
+ *     <pre>
+ *     my_codec.c:
+ *       vpx_codec_iface_t my_codec = {
+ *           "My Codec v1.0",
+ *           VPX_CODEC_ALG_ABI_VERSION,
+ *           ...
+ *       };
+ *     </pre>
+ *
+ * An application instantiates a specific decoder instance by using
+ * vpx_codec_dec_init() and a pointer to the algorithm's interface structure:
+ *     <pre>
+ *     my_app.c:
+ *       extern vpx_codec_iface_t my_codec;
+ *       {
+ *           vpx_codec_ctx_t algo;
+ *           int threads = 4;
+ *           vpx_codec_dec_cfg_t cfg = { threads, 0, 0 };
+ *           res = vpx_codec_dec_init(&algo, &my_codec, &cfg, 0);
+ *       }
+ *     </pre>
+ *
+ * Once initialized, the instance is manged using other functions from
+ * the vpx_codec_* family.

+// 1. src is not always 32-bit aligned, so don't call vld1_lane_u32(src).
+// 2. After refactoring the shared code in kernel loops with inline functions,
+// the decoder speed dropped a lot when using gcc compiler. Therefore there is
+// no refactoring for those parts by now.
+// 3. For horizontal convolve, there is an alternative optimization that
+// convolves a single row in each loop. For each row, 8 sample banks with 4 or 8
+// samples in each are read from memory: src, (src+1), (src+2), (src+3),
+// (src+4), (src+5), (src+6), (src+7), or prepared by vector extract
+// instructions. This optimization is much faster in speed unit test, but slowed
+// down the whole decoder by 5%.

+ * \brief Provides portable memory access primitives
+ *
+ * This function provides portable primitives for getting and setting of
+ * signed and unsigned integers in 16, 24, and 32 bit sizes. The operations
+ * can be performed on unaligned data regardless of hardware support for
+ * unaligned accesses.
+ *
+ * The type used to pass the integral values may be changed by defining
+ * MEM_VALUE_T with the appropriate type. The type given must be an integral
+ * numeric type.
+ *
+ * The actual functions instantiated have the MEM_VALUE_T type name pasted
+ * on to the symbol name. This allows the developer to instantiate these
+ * operations for multiple types within the same translation unit. This is
+ * of somewhat questionable utility, but the capability exists nonetheless.
+ * Users not making use of this functionality should call the functions
+ * without the type name appended, and the preprocessor will take care of
+ * it.
+ *
+ * NOTE: This code is not supported on platforms where char > 1 octet ATM.

+  Coefficients are rounded in such a way as to ensure their sum is still 128,
