[MPlayer-users] endless loop when building odml index

[Ivan Mitev]

hi, 

i have troubles with a big >3go avi file i just created with transcode 
(version 0.6.12, which has odml support). 

there is an endless loop when building the odml index.
if i put a printf() in libmpdemux/aviheader.c, after the "3rd for" (around 
line 505, after idx++), i see that mplayer is caught in an infinite loop. i 
can't fix it, as i don't understand anything to avi headers/index. 

i'm using the CVS version of april 1st (MPlayer-20040401); btw, maybe the 
problem is that transcode generates a buggy avi... 

mplayer -v output:
