i also get bit-exact decoding to raw video now that i tried this with ffmpeg.
the decoded stream is however in both cases not ok (you can see that ffplay
stops decoding) and there is the error message from ffmpeg '[mpeg2video]
mpeg_decode_postinit() failure'

the problem with the behaviour i described originally is with my own program
which does NOT use avformat; it uses only avcodec. my parser probably outputs
different packet boundaries from what avformat does with the same stream. is
this legal? and if so, is there a way to provide you with the test data
(including the packet boundaries) in some way?
