Member Function Documentation

bool avtranscoder::VideoGenerator::decodeNextFrame ( Frame &  frameBuffer )

virtual

Decode next frame.

Parameters

frameBuffer

the frame decoded the frameBuffer reference belongs to the decoder and is valid only until the next call to this function or until closing or flushing the decoder. The caller may not write to it.

Returns

status of decoding

Implements avtranscoder::IDecoder.

bool avtranscoder::VideoGenerator::decodeNextFrame ( Frame &  frameBuffer, const size_t  channelIndex  )

virtual

Decode substream of next frame.

Parameters

frameBuffer	the frame decoded
channelIndex	index of channel to extract

Returns

status of decoding

Implements avtranscoder::IDecoder.
