[MPlayer-users] Crash with backtrace when playing back demuxed .vc1 or .evo files

[infernix]

Yes, ffplay seems to play it back fine. I haven't been able to try the 
broken_very_badly sample, as it was cut from the end of an .evo, but 
both the .vc1 as well as the .evo I used in gdb play back fine.

> btw, please try also
> mplayer ... -vo jpeg

This works fine on both the .evo and .vc1.

> mplayer mf://*.jpg -fps 25

Works fine when the jpgs are generated from the .vc1, crashes if I 
generated them from the .evo. gdb output follows.
