[MPlayer-dev-eng] [PATCH] problem opening AVI/ODML files with idx option.

[Benjamin Zores]

Current MPlayer seems to have a problem opening some AVI files with
OpenDML's inside when using the -idx option.
In fact many GeeXboX users complained us about being unable to open some
divx files (but as most of them aren't power users they can't provide us
precise info but by divx i guess they were talking about .avi files) and
we do have the idex=yes param in our mplayer.conf file.

Here's a sample of a broken AVI file that let you reproduce the bug (3MB) :

So basically, it plays fine using -noidx (default) or -forceidx but ends
up immediatly using -idx.

Output is :

ODML (03tx): [0] 0x0000000015a1fdc6 0x0028 1
list_end=0x46A
AVI: dmlh found (size=248) (total_frames=62631)

AVI: Missing video stream!? Contact the author, it may be a bug :(

vo: x11 uninit called but X11 not inited..

Exiting... (End of file)


Attached is a patch that should restore a good behavior (i.e reading
OpenDML index if one is found and idx=yes).
