[MPlayer-users] Seeking bug in mplayer.

[P. Rybin]

Hi!
I've got this AVI file, and when it's simply played back, the audio and video are in sync. However, if I do some seeking, the sync is lost. The same thing happens if I start mplayer with the -forceidx option, so I don't think there's anything wrong with the index of the file.
This was observed with the CVS snapshot from 20020404, couldn't try it with a current snapshot because of another bug that is the subject of another report.

Cheers,
Pav

Don't know how relevant this is, but here are my system specs and other stuff:

SuSE 7.2 distro with stock 2.4.4 kernel
XFree86 4.1.0
nvidia geforce2 mx graphics card using the binary nvidia drivers
Athlon Thunderbird 900MHz cpu
512mb sdram
SB Live! using alsa 0.5 drivers

output of mplayer -v:
