- The samples of a multi-channel audio stream are stored in one continuousbuffer. Samples at the same timestamp are stored one after another. Forexample, for a stereo stream with channels L and R that contains sampleswith timestamps 0, 1, 2, etc., the samples are stored in one buffer as“L0 R0 L1 R1 L2 R2 ...”.kSbMediaAudioFrameStorageTypePlanar
- The samples of each channel are stored in their own continuous buffer.For example, for a stereo stream with channels L and R that containssamples with timestamps 0, 1, 2, etc., the samples are stored in twobuffers “L0 L1 L2 ...” and “R0 R1 R2 ...”.Possible audio sample types.

A structure describing the audio configuration parameters of a single audio output.
Members
An audio sequence header, which is a description of a given audio stream. This, in hexadecimal string form, acts as a set of instructions to the audio decoder.
The Sequence Header consists of a little-endian hexadecimal encoded WAVEFORMATEX
structure followed by an Audio-specific configuration field. The WAVEFORMATEX
structure is specified at: http://msdn.microsoft.com/en-us/library/dd390970(v=vs.85).aspx
Members
HDR (High Dynamic Range) Metadata common for HDR10 and WebM/VP9-based HDR formats, together with the ColorSpace. HDR reproduces a greater dynamic range of luminosity than is possible with standard digital imaging. See the Consumer Electronics Association press release: https://www.cta.tech/News/Press-Releases/2015/August/CEA-Defines-%E2%80%98HDR-Compatible%E2%80%99-Displays.aspx

SMPTE 2086 mastering data http://ieeexplore.ieee.org/document/7291707/ This standard specifies the metadata items to specify the color volume (the color primaries, white point, and luminance range) of the display that was used in mastering video content. The metadata is specified as a set of values independent of any specific digital representation. Also see the WebM container guidelines: https://www.webmproject.org/docs/container/
Members
The set of information required by the decoder or player for each video sample.
Members
Description
Returns information about whether the playback of the specific media described by mime
and encrypted using key_system
can be played.
Note that neither mime
nor key_system
can be NULL. This function returns kSbMediaSupportNotSupported
if either is NULL.
Declaration and definitions
#include "starboard/media.h" SbMediaSupportType SbMediaCanPlayMimeAndKeySystem(const char* mime, const char* key_system) { SB_UNREFERENCED_PARAMETER(mime); SB_UNREFERENCED_PARAMETER(key_system); return kSbMediaSupportTypeNotSupported; }
Parameters
Description
Retrieves the current physical audio configuration of audio output output_index
on this device and places it in out_configuration
, which must not be NULL.
This function returns false
if nothing could be determined on this platform or if output_index
does not exist on this device.
Declaration and definitions
#include "starboard/media.h" bool SbMediaGetAudioConfiguration( int output_index, SbMediaAudioConfiguration* out_configuration) { SB_UNREFERENCED_PARAMETER(output_index); SB_UNREFERENCED_PARAMETER(out_configuration); return false; }
Parameters
Description
Returns the number of audio outputs currently available on this device. Even if the number of outputs or their audio configurations can't be determined, it is expected that the platform will at least return a single output that supports at least stereo.
Declaration and definitions
#include "starboard/media.h" int SbMediaGetAudioOutputCount() { return 0; }
Description
Indicates whether output copy protection is currently enabled on all capable outputs. If true
, then non-protection-capable outputs are expected to be blanked.
Declaration and definitions
#include "starboard/media.h" #include "starboard/log.h" bool SbMediaIsOutputProtected() { return false; }
Description
Indicates whether this platform supports decoding video_codec
and audio_codec
along with decrypting using key_system
. If video_codec
is kSbMediaVideoCodecNone
or if audio_codec
is kSbMediaAudioCodecNone
, this function should return true
as long as key_system
is supported on the platform to decode any supported input formats.
Declaration and definitions
#include "starboard/media.h" SB_EXPORT bool SbMediaIsSupported(SbMediaVideoCodec /*video_codec*/, SbMediaAudioCodec /*audio_codec*/, const char* /*key_system*/) { return false; }
Parameters
Description
Enables or disables output copy protection on all capable outputs. If enabled, then non-protection-capable outputs are expected to be blanked.
The return value indicates whether the operation was successful, and the function returns a success even if the call is redundant in that it doesn't change the current value.
Declaration and definitions
#include "starboard/media.h" #include "starboard/log.h" bool SbMediaSetOutputProtection(bool enabled) { SB_UNREFERENCED_PARAMETER(enabled); return false; }
Parameters
