Cool, SKIP mode is very useful in embed platform. We implement it in tricky way
(implement it only in demuxer). But I wander can demuxer handle QOS? Video
decoder can handle QOS and can drop B or drop BP. Can demuxer handle QOS to
only output key frame to reduce file fetch? This will achieve SKIP
automatically. The reason of the proposal is application hard to decide which
speed need SKIP mode. Little resolution clip needn't SKIP even high rate
playback. Large resolution clip need SKIP even low rate playback.
