[MPlayer-users] flv file has extremely bad sync

[Jeremy Hansen]

I have an flv file, that has an extremely bad sync in mplayer. When
you start the video it runs fine for the first twenty seconds or so,
then the video speeds up at least double, probably more, but the audio
stays the right speed. The weird thing is there are no abnormal dumps
from the console (at least that I can tell), and gmplayer shows the
time of the video (ie the time display speeds up along with the
video). When it runs out of video, the program exits normally, without
errors.

I have svn 20606. The file plays fine with ffmpeg's ffplay r6868.

I have uploaded the file to the ftp incoming. It is listed as
family-guy-censored.flv

It seems it is using the ffmpeg decoder. I just checked and ffmpeg is
r6868 and mplayer is using r6869. When I get home from work I will
double check with the latest version of ffmpeg. Oh and this also
happened with RC1 (which is why I upgraded).

BTW here is my mplayer -v output.
