[MPlayer-users] mencoder audio problems

[Horváth Ágoston János]

Hello,

I'm having issues encoding the audio track of my MJPEG video using
mencoder SVN-31581:

- there is an added audio delay of 0.131;
- the last 5 seconds of the audio is cut off.

The command line is:

-ovc x264 -x264encopts "preset=veryslow:crf=$QUALITY" -oac mp3lame
-lameopts mode=3:q=5:aq=0

The output is:
