Member Function Documentation

bool avtranscoder::AudioDecoder::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::AudioDecoder::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.

void avtranscoder::AudioDecoder::flushDecoder ( )

virtual

Reset the internal decoder state / flush internal buffers.

Note

Should be called when seeking or when switching to a different stream.

Not sense for generators.

Reimplemented from avtranscoder::IDecoder.

void avtranscoder::AudioDecoder::setupDecoder ( const ProfileLoader::Profile &  profile = ProfileLoader::Profile() )

virtual

Setup the decoder.

Parameters

profile

set decoder parameters from the given profile

Note

Open the decoder.
