[FFmpeg-devel] [PATCH] Make RM demuxer demux more frames

[Kostya]

Attached patch fixes another braindamaged feature of RM container
not handled by lavf - multiple frames in one packet.
Actually, packet with the last slice of frame has real
subpacket length stored in 'pos' and the rest of packet
may be occupied by slices for the next frames (current demuxer
ignores that fact).
