ffmpeg detects avi/divx with xsub as broken

Reported by: someuser Owned by:
Priority: minor Component: avformat
Version: git-master Keywords: xsub avi
Cc: Blocked By:
Blocking: Reproduced by developer: yes
Analyzed by developer: no

Description

Summary of the bug:

When creating an AVI/DivX with XSub subtitles with FFmpeg the result plays fine on supported players but FFmpeg itself complains that the AVI has been generated by broken software. FFmpeg complains this also about AVIAddXSubs generated AVIs. The inputs are ok according to FFmpeg and this should be trivial to reproduce.

How to reproduce:

> ./ffmpeg -i test.avi
