class AcceleratedVideoDecoder

Defined at line 22 of file ../../src/media/third_party/chromium_media/media/gpu/accelerated_video_decoder.h

An AcceleratedVideoDecoder is a video decoder that requires support from an

external accelerator (typically a hardware accelerator) to partially offload

the decode process after parsing stream headers, and performing reference

frame and state management.

void SetStream (int32_t id, const DecoderBuffer & decoder_buffer)

Set the buffer owned by |decoder_buffer| as the current source of encoded

stream data. AcceleratedVideoDecoder doesn't have an ownership of the

buffer. |decoder_buffer| must be kept alive until Decode() returns

kRanOutOfStreamData. Pictures produced as a result of this call should be

assigned the passed stream |id|.

bool Flush ()

Have the decoder flush its state and trigger output of all previously

decoded surfaces. Return false on failure.

void Reset ()

Stop (pause) decoding, discarding all remaining inputs and outputs,

but do not flush decoder state, so that playback can be resumed later,

possibly from a different location.

To be called during decoding.

DecodeResult Decode ()

Try to decode more of the stream, returning decoded frames asynchronously.

Return when more stream is needed, when we run out of free surfaces, when

we need a new set of them, or when an error occurs.

gfx::Size GetPicSize ()

Return dimensions/visible rectangle/profile/bit depth/required number of

pictures that client should be ready to provide for the decoder to function

properly (of which up to GetNumReferenceFrames() might be needed for

internal decoding). To be used after Decode() returns kConfigChange.

TODO(https://fxbug.dev/42060469): Exposes if kConfigChange was caused by a keyframe
