Expand description

Video decoder trait.

Implements a push-pull decoding model:

Send compressed packets with send_packet
Receive decoded frames with receive_frame

§Example

while let Some(packet) = demuxer.read_packet()? {
    decoder.send_packet(&packet)?;
    while let Some(frame) = decoder.receive_frame()? {
        process_frame(frame);
    }
}
decoder.flush()?;
while let Some(frame) = decoder.receive_frame()? {
    process_frame(frame);
}
