[Mplayer-users] playback bug

[Stuart Meikle]

Hi folks,

i've got a slight playback bug in my version of mplayer. Audio becomes
unsynchronised with the video after -> <- up or down key presses, or if I
use the command line -sb or -ss options. I am playing large (100MB+) avi
files typically.

System info:

Mandrake 8.0 with updated X11 and kernel 2.4.7

uname = Linux localhost.localdomain 2.4.7 #4 Thu Aug 23 19:54:57 CEST 2001
i686 unknown

processor is AMD athlon, 128mb local ram.

libc-2.2.2.so linked as libc.so.6

X version 4.11

gcc version 2.96 (think Mandrake might have tweaked a couple of things
too)

as version = 2.10.91 compiled for i586-mandrake-linux

No compilation problems.

I've included a -v op file. Here's what I did to creat it:
time = 0 sec play avi file
time = 10sec , press up arrow to jump forwards a minute
time = 20sec , ditto
time = 30sec,  ditto
time = 40sec,  down arrow pressed
time = 50sec,  ditto
time = 60sec, ctrl-c

Audio does not become corrupted but does begin to lag behind the video
playback, by up to 20 secs i guess.

Thanks,

Stuart
