[MPlayer-users] Mplayer plays slowly video files from my digital camera

[Anthony Hocquet]

That's weird. I have almost the same output and it plays slowly. If I
disable sound using option "-ac null" then it plays perfectly. So it's not a
video codec problem, but more an audio codec problem.
Here is my output :
