+
+
+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.
+

+
+
+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 targetting
+      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
+          SSE2/SSSE3 optimizations for build_predictors_mbuv{,_s}().
+          Make hor UV predict ~2x faster (73 vs 132 cycles) using SSSE3.
+          Removed redundant checks
+          Reduced structure sizes
+          utilize preload in ARMv6 MC/LPF/Copy routines
+          ARM optimized quantization, dfct, variance, subtract
+          Increase chrow row alignment to 16 bytes.
+          disable trellis optimization for first pass
+          Write SSSE3 sub-pixel filter function
+          Improve SSE2 half-pixel filter funtions

+
+
+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.
+
+  - Enhancements:
+      vpxenc --psnr shows a summary when encode completes
+      --tune=ssim option to enable activity masking
+      improved postproc visualizations for development
+      updated support for Apple iOS to SDK 4.2
+      query decoder to determine which reference frames were updated
+      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
+        FDCT optimizations.

+        Full search SAD function optimization in SSE4.1
+        Improve MV prediction accuracy to achieve performance gain
+        Improve MV prediction in vp8_pick_inter_mode() for speed>3
+
+  - 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.

+      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

+      Build fixes for darwin-icc
+
+  - Speed:
+      20-40% (average 28%) improvement in libvpx decoder speed,
+      including:
+        Rewrite vp8_short_walsh4x4_sse2()
+        Optimizations on the loopfilters.
+        Miscellaneous improvements for Atom

+README - 23 March 2015
+
+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.
+    * All Windows builds require that Cygwin[2] be installed.
+    * Building the documentation requires Doxygen[3]. If you do not
+      have this package, the install-docs option will be disabled.
+    * Downloading the data for the unit tests requires curl[4] 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[5]. These requirements are optional if not running the unit
+      tests.
+
+    [1]: http://www.tortall.net/projects/yasm
+    [2]: http://www.cygwin.com
+    [3]: http://www.doxygen.org
+    [4]: http://curl.haxx.se
+    [5]: 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. 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:
+
+    armv6-linux-rvct
+    armv6-linux-gcc
+    armv6-none-rvct
+    arm64-darwin-gcc
+    armv7-android-gcc

+    armv7-win32-vs14
+    armv7s-darwin-gcc
+    mips32-linux-gcc
+    mips64-linux-gcc
+    sparc-solaris-gcc
+    x86-android-gcc

+    x86-win32-vs7
+    x86-win32-vs8
+    x86-win32-vs9
+    x86-win32-vs10
+    x86-win32-vs11
+    x86-win32-vs12
+    x86-win32-vs14
+    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-iphonesimulator-gcc
+    x86_64-linux-gcc
+    x86_64-linux-icc
+    x86_64-solaris-gcc
+    x86_64-win64-gcc
+    x86_64-win64-vs8
+    x86_64-win64-vs9
+    x86_64-win64-vs10
+    x86_64-win64-vs11
+    x86_64-win64-vs12
+    x86_64-win64-vs14
+    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.
+
+  5. 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
+
+SUPPORT
+  This library is an open source project supported by its community. Please
+  please email webm-discuss@webmproject.org for help.

+# This file is to be used for compiling libvpx for Android using the NDK.

+# ./libvpx/configure --target=armv7-android-gcc --disable-examples \
+#                    --sdk-path=/opt/android-ndk-r6b/
+#
+# 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 jni/libvpx/build/make/Android.mk
+#
+# There are currently two TARGET_ARCH_ABI targets for ARM.
+# armeabi and armeabi-v7a.  armeabi-v7a is selected by creating an
+# Application.mk in the jni directory that contains:
+# APP_ABI := armeabi-v7a
+#
+# By default libvpx will detect at runtime the existance of NEON extension.
+# For this we import the 'cpufeatures' module from the NDK sources.
+# libvpx can also be configured without this runtime detection method.
+# Configuring with --disable-runtime-cpu-detect will assume presence of NEON.
+# Configuring with --disable-runtime-cpu-detect --disable-neon \
+#     --disable-neon-asm
+# will remove any NEON dependency.
+
+# To change to building armeabi, run ./libvpx/configure again, but with

+// 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

+// 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.

+
+      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,
+ * except that you don't need to include two pages of legalese
+ * with every copy.

+ * 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 --sdk-path=$NDK
+
+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=gnustl_static
+
+Note: Both adb and ndk-build are available prebuilt at:
+  https://chromium.googlesource.com/android_tools
+
+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

+Description:
+Google's framework for writing C++ tests on a variety of platforms
+(Linux, Mac OS X, Windows, Windows CE, Symbian, etc).  Based on the
+xUnit architecture.  Supports automatic test discovery, a rich set of
+assertions, user-defined assertions, death tests, fatal and non-fatal
+failures, various options for running the tests, and XML test report
+generation.
+
+Local Modifications:
+- Removed unused declarations of kPathSeparatorString to have warning
+  free build.
+- Added GTEST_ATTRIBUTE_UNUSED_ to test registering dummies in TEST_P
+  and INSTANTIATE_TEST_CASE_P to remove warnings about unused variables

+Changes for 1.7.0:
+
+* New feature: death tests are supported on OpenBSD and in iOS
+  simulator now.
+* New feature: Google Test now implements a protocol to allow
+  a test runner to detect that a test program has exited
+  prematurely and report it as a failure (before it would be
+  falsely reported as a success if the exit code is 0).
+* New feature: Test::RecordProperty() can now be used outside of the
+  lifespan of a test method, in which case it will be attributed to
+  the current test case or the test program in the XML report.
+* New feature (potentially breaking): --gtest_list_tests now prints
+  the type parameters and value parameters for each test.
+* Improvement: char pointers and char arrays are now escaped properly
+  in failure messages.
+* Improvement: failure summary in XML reports now includes file and
+  line information.
+* Improvement: the <testsuites> XML element now has a timestamp attribute.
+* Improvement: When --gtest_filter is specified, XML report now doesn't
+  contain information about tests that are filtered out.
+* Fixed the bug where long --gtest_filter flag values are truncated in
+  death tests.
+* Potentially breaking change: RUN_ALL_TESTS() is now implemented as a
+  function instead of a macro in order to work better with Clang.
+* Compatibility fixes with C++ 11 and various platforms.
+* Bug/warning fixes.
+
+Changes for 1.6.0:
+
+* New feature: ADD_FAILURE_AT() for reporting a test failure at the
+  given source location -- useful for writing testing utilities.
+* New feature: the universal value printer is moved from Google Mock
+  to Google Test.
+* New feature: type parameters and value parameters are reported in
+  the XML report now.
+* A gtest_disable_pthreads CMake option.
+* Colored output works in GNU Screen sessions now.
+* Parameters of value-parameterized tests are now printed in the
+  textual output.
+* Failures from ad hoc test assertions run before RUN_ALL_TESTS() are
+  now correctly reported.
+* Arguments of ASSERT_XY and EXPECT_XY no longer need to support << to
+  ostream.
+* More complete handling of exceptions.
+* GTEST_ASSERT_XY can be used instead of ASSERT_XY in case the latter
+  name is already used by another library.
+* --gtest_catch_exceptions is now true by default, allowing a test
+  program to continue after an exception is thrown.
+* Value-parameterized test fixtures can now derive from Test and
+  WithParamInterface<T> separately, easing conversion of legacy tests.
+* Death test messages are clearly marked to make them more
+  distinguishable from other messages.
+* Compatibility fixes for Android, Google Native Client, MinGW, HP UX,
+  PowerPC, Lucid autotools, libCStd, Sun C++, Borland C++ Builder (Code Gear),
+  IBM XL C++ (Visual Age C++), and C++0x.
+* Bug fixes and implementation clean-ups.
+* Potentially incompatible changes: disables the harmful 'make install'
+  command in autotools.
+
+Changes for 1.5.0:
+
+ * New feature: assertions can be safely called in multiple threads
+   where the pthreads library is available.
+ * New feature: predicates used inside EXPECT_TRUE() and friends
+   can now generate custom failure messages.
+ * New feature: Google Test can now be compiled as a DLL.
+ * New feature: fused source files are included.
+ * New feature: prints help when encountering unrecognized Google Test flags.
+ * Experimental feature: CMake build script (requires CMake 2.6.4+).
+ * Experimental feature: the Pump script for meta programming.
+ * double values streamed to an assertion are printed with enough precision
+   to differentiate any two different values.
+ * Google Test now works on Solaris and AIX.
+ * Build and test script improvements.
+ * Bug fixes and implementation clean-ups.
+
+ Potentially breaking changes:
+
+ * Stopped supporting VC++ 7.1 with exceptions disabled.
+ * Dropped support for 'make install'.
+
+Changes for 1.4.0:
+
+ * New feature: the event listener API
+ * New feature: test shuffling
+ * New feature: the XML report format is closer to junitreport and can
+   be parsed by Hudson now.
+ * New feature: when a test runs under Visual Studio, its failures are
+   integrated in the IDE.
+ * New feature: /MD(d) versions of VC++ projects.
+ * New feature: elapsed time for the tests is printed by default.
+ * New feature: comes with a TR1 tuple implementation such that Boost
+   is no longer needed for Combine().
+ * New feature: EXPECT_DEATH_IF_SUPPORTED macro and friends.
+ * New feature: the Xcode project can now produce static gtest
+   libraries in addition to a framework.

+   .cc file for easy deployment.
+ * New feature: support for distributing test functions to multiple
+   machines (requires support from the test runner).
+ * Bug fixes and implementation clean-ups.
+
+Changes for 1.2.1:
+
+ * Compatibility fixes for Linux IA-64 and IBM z/OS.

+Google C++ Testing Framework
+============================
+
+http://code.google.com/p/googletest/
+
+Overview
+--------
+
+Google's framework for writing C++ tests on a variety of platforms
+(Linux, Mac OS X, Windows, Windows CE, Symbian, etc).  Based on the
+xUnit architecture.  Supports automatic test discovery, a rich set of
+assertions, user-defined assertions, death tests, fatal and non-fatal
+failures, various options for running the tests, and XML test report
+generation.
+
+Please see the project page above for more information as well as the
+mailing list for questions, discussions, and development.  There is
+also an IRC channel on OFTC (irc.oftc.net) #gtest available.  Please
+join us!
+
+Requirements for End Users
+--------------------------
+
+Google Test is designed to have fairly minimal requirements to build
+and use with your projects, but there are some.  Currently, we support
+Linux, Windows, Mac OS X, and Cygwin.  We will also make our best
+effort to support other platforms (e.g. Solaris, AIX, and z/OS).
+However, since core members of the Google Test project have no access
+to these platforms, Google Test may have outstanding issues there.  If
+you notice any problems on your platform, please notify
+googletestframework@googlegroups.com.  Patches for fixing them are
+even more welcome!
+
+### Linux Requirements ###
+
+These are the base requirements to build and use Google Test from a source
+package (as described below):
+  * GNU-compatible Make or gmake
+  * POSIX-standard shell
+  * POSIX(-2) Regular Expressions (regex.h)
+  * A C++98-standard-compliant compiler
+
+### Windows Requirements ###
+
+  * Microsoft Visual C++ 7.1 or newer
+
+### Cygwin Requirements ###
+
+  * Cygwin 1.5.25-14 or newer
+
+### Mac OS X Requirements ###
+
+  * Mac OS X 10.4 Tiger or newer
+  * Developer Tools Installed
+
+Also, you'll need CMake 2.6.4 or higher if you want to build the
+samples using the provided CMake script, regardless of the platform.
+
+Requirements for Contributors
+-----------------------------
+
+We welcome patches.  If you plan to contribute a patch, you need to
+build Google Test and its own tests from an SVN checkout (described
+below), which has further requirements:
+
+  * Python version 2.3 or newer (for running some of the tests and
+    re-generating certain source files from templates)
+  * CMake 2.6.4 or newer
+
+Getting the Source
+------------------
+
+There are two primary ways of getting Google Test's source code: you
+can download a stable source release in your preferred archive format,
+or directly check out the source from our Subversion (SVN) repositary.
+The SVN checkout requires a few extra steps and some extra software
+packages on your system, but lets you track the latest development and
+make patches much more easily, so we highly encourage it.
+
+### Source Package ###
+
+Google Test is released in versioned source packages which can be
+downloaded from the download page [1].  Several different archive
+formats are provided, but the only difference is the tools used to
+manipulate them, and the size of the resulting file.  Download
+whichever you are most comfortable with.
+
+  [1] http://code.google.com/p/googletest/downloads/list
+
+Once the package is downloaded, expand it using whichever tools you
+prefer for that type.  This will result in a new directory with the
+name "gtest-X.Y.Z" which contains all of the source code.  Here are
+some examples on Linux:
+
+  tar -xvzf gtest-X.Y.Z.tar.gz
+  tar -xvjf gtest-X.Y.Z.tar.bz2
+  unzip gtest-X.Y.Z.zip
+
+### SVN Checkout ###
+
+To check out the main branch (also known as the "trunk") of Google
+Test, run the following Subversion command:
+
+  svn checkout http://googletest.googlecode.com/svn/trunk/ gtest-svn
+
+Setting up the Build
+--------------------
+
+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.
+
+### Generic Build Instructions ###
+
+Suppose you put Google Test in directory ${GTEST_DIR}.  To build it,
+create a library build target (or a project as called by Visual Studio
+and Xcode) to compile
+
+  ${GTEST_DIR}/src/gtest-all.cc
+
+with ${GTEST_DIR}/include in the system header search path and ${GTEST_DIR}
+in the normal header search path.  Assuming a Linux-like system and gcc,
+something like the following will do:
+
+  g++ -isystem ${GTEST_DIR}/include -I${GTEST_DIR} \
+      -pthread -c ${GTEST_DIR}/src/gtest-all.cc
+  ar -rv libgtest.a gtest-all.o
+
+(We need -pthread as Google Test uses threads.)
+
+Next, you should compile your test source file with
+${GTEST_DIR}/include in the system header search path, and link it
+with gtest and any other necessary libraries:
+
+  g++ -isystem ${GTEST_DIR}/include -pthread path/to/your_test.cc libgtest.a \
+      -o your_test
+
+As an example, the make/ directory contains a Makefile that you can
+use to build Google Test on systems where GNU make is available
+(e.g. Linux, Mac OS X, and Cygwin).  It doesn't try to build Google
+Test's own tests.  Instead, it just builds the Google Test library and
+a sample test.  You can use it as a starting point for your own build
+script.
+
+If the default settings are correct for your environment, the
+following commands should succeed:
+
+  cd ${GTEST_DIR}/make
+  make
+  ./sample1_unittest
+
+If you see errors, try to tweak the contents of make/Makefile to make
+them go away.  There are instructions in make/Makefile on how to do
+it.
+
+### Using CMake ###
+
+Google Test comes with a CMake build script (CMakeLists.txt) that can
+be used on a wide range of platforms ("C" stands for cross-platofrm.).
+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.  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 Vistual 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.
+
+### Legacy Build Scripts ###
+
+Before settling on CMake, we have been providing hand-maintained build
+projects/scripts for Visual Studio, Xcode, and Autotools.  While we
+continue to provide them for convenience, they are not actively
+maintained any more.  We highly recommend that you follow the
+instructions in the previous two sections to integrate Google Test
+with your existing build system.
+
+If you still need to use the legacy build scripts, here's how:
+
+The msvc\ folder contains two solutions with Visual C++ projects.
+Open the gtest.sln or gtest-md.sln file using Visual Studio, and you
+are ready to build Google Test the same way you build any Visual
+Studio project.  Files that have names ending with -md use DLL
+versions of Microsoft runtime libraries (the /MD or the /MDd compiler
+option).  Files without that suffix use static versions of the runtime
+libraries (the /MT or the /MTd option).  Please note that one must use
+the same option to compile both gtest and the test code.  If you use
+Visual Studio 2005 or above, we recommend the -md version as /MD is
+the default for new projects in these versions of Visual Studio.
+
+On Mac OS X, open the gtest.xcodeproj in the xcode/ folder using
+Xcode.  Build the "gtest" target.  The universal binary framework will
+end up in your selected build directory (selected in the Xcode
+"Preferences..." -> "Building" pane and defaults to xcode/build).
+Alternatively, at the command line, enter:
+
+  xcodebuild
+
+This will build the "Release" configuration of gtest.framework in your
+default build location.  See the "xcodebuild" man page for more
+information about building different configurations and building in
+different locations.
+
+If you wish to use the Google Test Xcode project with Xcode 4.x and
+above, you need to either:
+ * update the SDK configuration options in xcode/Config/General.xconfig.
+   Comment options SDKROOT, MACOS_DEPLOYMENT_TARGET, and GCC_VERSION. If
+   you choose this route you lose the ability to target earlier versions
+   of MacOS X.
+ * Install an SDK for an earlier version. This doesn't appear to be
+   supported by Apple, but has been reported to work
+   (http://stackoverflow.com/questions/5378518).
+
+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.
+
+### Choosing a TR1 Tuple Library ###
+
+Some Google Test features require the C++ Technical Report 1 (TR1)
+tuple library, which is not yet available with all compilers.  The
+good news is that Google Test implements a subset of TR1 tuple that's
+enough for its own need, and will automatically use this when the
+compiler doesn't provide TR1 tuple.
+
+Usually you don't need to care about which tuple library Google Test
+uses.  However, if your project already uses TR1 tuple, you need to
+tell Google Test to use the same TR1 tuple library the rest of your
+project uses, or the two tuple implementations will clash.  To do
+that, add
+
+  -DGTEST_USE_OWN_TR1_TUPLE=0
+
+to the compiler flags while compiling Google Test and your tests.  If
+you want to force Google Test to use its own tuple library, just add
+
+  -DGTEST_USE_OWN_TR1_TUPLE=1
+
+to the compiler flags instead.
+
+If you don't want Google Test to use tuple at all, add
+
+  -DGTEST_HAS_TR1_TUPLE=0
+
+and all features using tuple will be disabled.
+
+### 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.
+
+Upgrating from an Earlier Version
+---------------------------------
+
+We strive to keep Google Test releases backward compatible.
+Sometimes, though, we have to make some breaking changes for the
+users' long-term benefits.  This section describes what you'll need to
+do if you are upgrading from an earlier version of Google Test.
+
+### Upgrading from 1.3.0 or Earlier ###
+
+You may need to explicitly enable or disable Google Test's own TR1
+tuple library.  See the instructions in section "Choosing a TR1 Tuple
+Library".
+
+### Upgrading from 1.4.0 or Earlier ###
+
+The Autotools build script (configure + make) is no longer officially
+supportted.  You are encouraged to migrate to your own build system or
+use CMake.  If you still need to use Autotools, you can find
+instructions in the README file from Google Test 1.4.0.
+
+On platforms where the pthread library is available, Google Test uses
+it in order to be thread-safe.  See the "Multi-threaded Tests" section
+for what this means to your build script.
+
+If you use Microsoft Visual C++ 7.1 with exceptions disabled, Google
+Test will no longer compile.  This should affect very few people, as a
+large portion of STL (including <string>) doesn't compile in this mode
+anyway.  We decided to stop supporting it in order to greatly simplify
+Google Test's implementation.
+
+Developing Google Test
+----------------------
+
+This section discusses how to make your own changes to Google Test.
+
+### Testing Google Test Itself ###
+
+To make sure your changes work as intended and don't break existing
+functionality, you'll want to compile and run Google Test's own tests.
+For that you can use CMake:
+
+  mkdir mybuild
+  cd mybuild
+  cmake -Dgtest_build_tests=ON ${GTEST_DIR}
+
+Make sure you have Python installed, as some of Google Test's tests
+are written in Python.  If the cmake command complains about not being
+able to find Python ("Could NOT find PythonInterp (missing:
+PYTHON_EXECUTABLE)"), try telling it explicitly where your Python
+executable can be found:
+
+  cmake -DPYTHON_EXECUTABLE=path/to/python -Dgtest_build_tests=ON ${GTEST_DIR}
+
+Next, you can build Google Test and all of its own tests.  On *nix,
+this is usually done by 'make'.  To run the tests, do
+
+  make test
+
+All tests should pass.
+
+### Regenerating Source Files ###
+
+Some of Google Test's source files are generated from templates (not
+in the C++ sense) using a script.  A template file is named FOO.pump,
+where FOO is the name of the file it will generate.  For example, the
+file include/gtest/internal/gtest-type-util.h.pump is used to generate
+gtest-type-util.h in the same directory.
+
+Normally you don't need to worry about regenerating the source files,
+unless you need to modify them.  In that case, you should modify the
+corresponding .pump files instead and run the pump.py Python script to
+regenerate them.  You can find pump.py in the scripts/ directory.
+Read the Pump manual [2] for how to use it.

+//                parameter iff 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
+//                compile inside functions where ASSERT_DEATH doesn't
+//                compile.
+//

+//
+//   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:
+//
+//   On POSIX-compliant systems (*nix), we use the <regex.h> library,
+//   which uses the POSIX extended regex syntax.
+//
+//   On other platforms (e.g. Windows), 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.
+//
+// TODO(wan@google.com): make thread-safe death tests search the PATH.

+// 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_CASE_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 case
+// each with parameter values "meeny", "miny", and "moe".
+
+INSTANTIATE_TEST_CASE_P(InstantiationName,
+                        FooTest,
+                        Values("meeny", "miny", "moe"));
+
+// To distinguish different instances of the pattern, (yes, you
+// can instantiate it more then once) the first argument to the
+// INSTANTIATE_TEST_CASE_P macro is a prefix that will be added to the
+// actual test case name. Remember to pick unique prefixes for different
+// instantiations. The tests from the instantiation above will have
+// these names:
+//
+//    * InstantiationName/FooTest.DoesBlah/0 for "meeny"
+//    * InstantiationName/FooTest.DoesBlah/1 for "miny"
+//    * InstantiationName/FooTest.DoesBlah/2 for "moe"
+//    * InstantiationName/FooTest.HasBlahBlah/0 for "meeny"
+//    * InstantiationName/FooTest.HasBlahBlah/1 for "miny"
+//    * InstantiationName/FooTest.HasBlahBlah/2 for "moe"
+//
+// You can use these names in --gtest_filter.
+//
+// This statement will instantiate all tests from FooTest again, each
+// with parameter values "cat" and "dog":
+
+const char* pets[] = {"cat", "dog"};
+INSTANTIATE_TEST_CASE_P(AnotherInstantiationName, FooTest, ValuesIn(pets));
+
+// The tests from the instantiation above will have these names:
+//
+//    * AnotherInstantiationName/FooTest.DoesBlah/0 for "cat"
+//    * AnotherInstantiationName/FooTest.DoesBlah/1 for "dog"
+//    * AnotherInstantiationName/FooTest.HasBlahBlah/0 for "cat"
+//    * AnotherInstantiationName/FooTest.HasBlahBlah/1 for "dog"
+//
+// Please note that INSTANTIATE_TEST_CASE_P will instantiate all tests
+// in the given test case, whether their definitions come before or
+// AFTER the INSTANTIATE_TEST_CASE_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> {
+  // The usual test fixture members go here too.
+};
+
+TEST_F(BaseTest, HasFoo) {
+  // This is an ordinary non-parameterized test.
+}
+
+TEST_P(DerivedTest, DoesBlah) {
+  // GetParam works just the same here as if you inherit from TestWithParam.
+  EXPECT_TRUE(foo.Blah(GetParam()));

+// A "smart" pointer type with reference tracking.  Every pointer to a
+// particular object is kept on a circular linked list.  When the last pointer
+// to an object is destroyed or reassigned, the object is deleted.
+//
+// Used properly, this deletes the object when the last reference goes away.
+// There are several caveats:
+// - Like all reference counting schemes, cycles lead to leaks.
+// - Each smart pointer is actually two pointers (8 bytes instead of 4).
+// - Every time a pointer is assigned, the entire list of pointers to that
+//   object is traversed.  This class is therefore NOT SUITABLE when there
+//   will often be more than two or three pointers to a particular object.
+// - References are only tracked as long as linked_ptr<> objects are copied.
+//   If a linked_ptr<> is converted to a raw pointer and back, BAD THINGS
+//   will happen (double deletion).
+//
+// A good use of this class is storing object references in STL containers.
+// You can safely put linked_ptr<> in a vector<>.
+// Other uses may not be as good.
+//
+// Note: If you use an incomplete type with linked_ptr<>, the class
+// *containing* linked_ptr<> must have a constructor and destructor (even
+// if they do nothing!).
+//
+// Bill Gibbons suggested we use something like this.
+//
+// Thread Safety:
+//   Unlike other linked_ptr implementations, in this implementation
+//   a linked_ptr object is thread-safe in the sense that:
+//     - it's safe to copy linked_ptr objects concurrently,
+//     - it's safe to copy *from* a linked_ptr and read its underlying
+//       raw pointer (e.g. via get()) concurrently, and
+//     - it's safe to write to two linked_ptrs that point to the same
+//       shared object concurrently.
+// TODO(wan@google.com): rename this to safe_linked_ptr to avoid
+// confusion with normal linked_ptr.

+//
+// In the following sample, tests from test case FooTest are instantiated

+// Range(start, end, step)
+//   - returns a generator producing a sequence of values {start, start+step,
+//     start+step+step, ..., }.
+// Notes:
+//   * The generated sequences never include end. For example, Range(1, 5)
+//     returns a generator producing a sequence {1, 2, 3, 4}. Range(1, 9, 2)
+//     returns a generator producing {1, 3, 5, 7}.

+//     floating-point type or a user defined type satisfying these conditions:
+//     * It must be assignable (have operator=() defined).
+//     * It must have operator+() (operator+(int-compatible type) for
+//       two-operand version).
+//     * It must have operator<() defined.
+//     Elements in the resulting sequences will also have that type.

+// Combine() allows the user to combine two or more sequences to produce
+// values of a Cartesian product of those sequences' elements.
+//
+// Synopsis:
+// Combine(gen1, gen2, ..., genN)
+//   - returns a generator producing sequences with elements coming from
+//     the Cartesian product of elements from the sequences generated by
+//     gen1, gen2, ..., genN. The sequence elements will have a type of
+//     tuple<T1, T2, ..., TN> where T1, T2, ..., TN are the types
+//     of elements from sequences produces by gen1, gen2, ..., genN.
+//
+// Combine can have up to 10 arguments. This number is currently limited
+// by the maximum number of elements in the tuple implementation used by Google
+// Test.
+//
+// Example:
+//
+// This will instantiate tests in test case AnimalTest each one with
+// the parameter values tuple("cat", BLACK), tuple("cat", WHITE),
+// tuple("dog", BLACK), and tuple("dog", WHITE):
+//
+// enum Color { BLACK, GRAY, WHITE };
+// class AnimalTest
+//     : public testing::TestWithParam<tuple<const char*, Color> > {...};
+//
+// TEST_P(AnimalTest, AnimalLooksNice) {...}
+//
+// INSTANTIATE_TEST_CASE_P(AnimalVariations, AnimalTest,
+//                         Combine(Values("cat", "dog"),
+//                                 Values(BLACK, WHITE)));
+//
+// This will instantiate tests in FlagDependentTest with all variations of two
+// Boolean flags:
+//
+// class FlagDependentTest
+//     : public testing::TestWithParam<tuple<bool, bool> > {
+//   virtual void SetUp() {
+//     // Assigns external_flag_1 and external_flag_2 values from the tuple.
+//     tie(external_flag_1, external_flag_2) = GetParam();
+//   }
+// };
+//
+// TEST_P(FlagDependentTest, TestFeature1) {
+//   // Test your code using external_flag_1 and external_flag_2 here.
+// }
+// INSTANTIATE_TEST_CASE_P(TwoBoolSequence, FlagDependentTest,
+//                         Combine(Bool(), Bool()));

+// different types any number of times, in any number of translation
+// units.
+//
+// If you are designing an interface or concept, you can define a
+// suite of type-parameterized tests to verify properties that any
+// valid implementation of the interface/concept should have.  Then,
+// each implementation can easily instantiate the test suite to verify
+// that it conforms to the requirements, without having to write
+// similar tests repeatedly.  Here's an example:
+
+#if 0
+
+// First, define a fixture class template.  It should be parameterized
+// by a type.  Remember to derive it from testing::Test.
+template <typename T>
+class FooTest : public testing::Test {
+  ...

+// Next, declare that you will define a type-parameterized test case
+// (the _P suffix is for "parameterized" or "pattern", whichever you
+// prefer):

+  // Inside a test, refer to TypeParam to get the type parameter.
+  TypeParam n = 0;
+  ...
+}
+
+TYPED_TEST_P(FooTest, HasPropertyA) { ... }

+// 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

+//
+//   2. The {ASSERT|EXPECT}_??() macros do pointer comparisons on
+//   pointers (in particular, C strings).  Therefore, if you use it
+//   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(expected, actual) is preferred to

+//
+// 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 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.

+
+; Unlike the rest of x264, this file is available under an ISC license, as it

+; e.g.
+; cglobal foo, 2,3,0, dst, src, tmp
+; declares a function (foo), taking two args (dst and src) and one local variable (tmp)

+; which are slow when a normal ret follows a branch.

+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.
+Expand PIC default to macho64 and respect CONFIG_PIC from libvpx
+Set 'private_extern' visibility for macho targets.
+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

+; 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

+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."

+/*! \page usage_decode Decoding
+
+    The vpx_codec_decode() function is at the core of the decode loop. It
+    processes packets of compressed data passed by the application, producing
+    decoded images. The decoder expects packets to comprise exactly one image
+    frame of data. Packets \ref MUST be passed in decode order. If the
+    application wishes to associate some data with the frame, the
+    <code>user_priv</code> member may be set. The <code>deadline</code>
+    parameter controls the amount of time in microseconds the decoder should
+    spend working on the frame. This is typically used to support adaptive
+    \ref usage_postproc based on the amount of free CPU time. For more
+    information on the <code>deadline</code> parameter, see \ref usage_deadline.
+
+    \ref samples
+
+
+    \section usage_cb Callback Based Decoding
+    There are two methods for the application to access decoded frame data. Some
+    codecs support asynchronous (callback-based) decoding \ref usage_features
+    that allow the application to register a callback to be invoked by the
+    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.

+ * 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 + ((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.
+ * The levels used are:
+ * diff       adjustment w/o motion correction   adjustment w/ motion correction

+ * The following 2 functions ('cal_nmvjointsadcost' and                *
+ * '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.                *

+ *     </pre>
+ *
+ * An application instantiates a specific decoder instance by using

+ * 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.
