Hello,
I'm encoding some videos from my camera (mjpeg+mp3) to x264+aac in FFmpeg. Here's the command line I use:
What happens is... when I play out.mkv in ffplay, it plays fine. When I play it in mplayer, audio is played a bit ahead of the video. It is possible to play out.mkv in mplayer in sync, when I add "-autosync 1000" option to mplayer command... Other videos (those not encoded by me) play fine without this option.
It's the same without "-async 1000" in FFmpeg command... I'm using newest FFmpeg (2013/04/01). This behavior replicable with all older versions I tried so far.
What's wrong with my command?
