Member Function Documentation

◆ dequeue_frame()

AVFrame * Video::VideoDecoder::dequeue_frame ( )
overridevirtualnoexcept

Implements Video::VideoInterface.

◆ release_frame()

void Video::VideoDecoder::release_frame ( AVFrame *  frame)
overridevirtualnoexcept

Implements Video::VideoInterface.

◆ seek()

void Video::VideoDecoder::seek ( int64_t  flicks)
overridevirtual

Asks for the frames from this playback time on; a source that cannot seek ignores it.

Reimplemented from Video::VideoInterface.
