[MPlayer-dev-eng] [PATCH] make AVI -forceidx search inside chunks > 1 MB

[Reimar Döffinger]

Hello,
attached patch would change avi demuxer behaviour to not skip any AVI
chunks > 1 MB but instead search inside those for stream data as well.
This admittedly is somewhat hackish (esp. due to the fixed 1 MB limit),
but it helps _a lot_ with playing partial or broken files, before
-forceidx would usually just stop at the first damage, now it usually
recognizes the whole file.
Ok to apply? Should the 1 MB be made an option or changed to some other
value?

Greetings,
Reimar Döffinger
