Codec can output multiple frames per AVPacket
Normally demuxers return one frame at a time, demuxers which do not do
are connected to a parser to split what they return into proper frames.
This flag is reserved to the very rare category of codecs which have a
bitstream that cannot be split into frames without timeconsuming
operations like full decoding. Demuxers carrying such bitstreams thus
may return multiple frames in a packet. This has many disadvantages like
prohibiting stream copy in many cases thus it should only be considered
as a last resort.
