Hey,
I found some strange rm files again. here I paste the -v output of mplayer:

the chunk_id is quite strange, it has only the last two letters, and
chunk_size seems have some sort of problems too. And it come up with a video
stream first while in my other rm file video streams is always after a audio
stream.
Now I think the problem is in the '### skipping' line, mplayer skipped too
much. So I think for this file codec info should be hide in somewhere else.
But like Balatoni said it's really a boring thing to figure it out and I'm
almost got crash with these file. So I gonna leave it to you who know real
format better than me;), I will upload a sample to
ftp.mplayerhq.hu/MPlayer/incoming/strange.rm, you can check it out and test.
