Description
Summary of the bug:
I can't ffmpeg get to cooperate with any videos created with the catcam http://www.mr-lee-catcam.de/
Videos work in vlc, windows media player, mplayer and mencoder can convert them. But ffmpeg won't do anything.
How to reproduce:
$ ffmpeg -c:v avrn -loglevel trace -an -r:v 30 -i PICT0001.AVI -vf scale=640:480 -an katze.mpg

VLC also tells me the header is defective.
This is a bug in catcam, not in ffmpeg. Send them a bug report.

Replying to robijn:

That may be so, but the beauty of ffmpeg is that it can usually handle these situations. And an example was attached so that devs can figure out how exactly to handle this since playback works fine. A warning message would be nice, but if processing can still occur that would be ideal. Sometimes you just want to get it away from the avi format and into something else that doesn't have errors.
Please provide a sample video.
