[MPlayer-users] rebuilding index introduces a seeking problem

[Joonas Koivunen]

hey there,

i just recently acquired dvl-animatrix.avi, which is encoded with XVID (judged 
by the fourcc) with mp3 audio. i thought i heard some progressive audio 
desync, getting stronger in the end of the film so i wanted to play it with 
mplayers index. with the original index, seeking works well (seeks to 
keyframe) but with the mplayer index it seeks to somewhere else, and it takes 
1-15 seconds for the messynes go away. i've had this problem with other xvid 
and divx encoded videos too.

i remember reading somewhere that xvid supports variable keyframe intervals, 
so could this be the cause? should mplayer/mencoder be able to put up a index 
for this sort of a video stream?
