Comment (by cehoyos):

 Replying to [ticket:3394 tessus]:
 > I copy a video stream and convert an aac audio stream from an mp4 file
 to an mkv file. The resulting mkv file is broken. It doesn't play on HW
 players (e.g. WD TV Media box) and stops in VLC as well.

 I tested the following command line:
 {{{
 $ ffmpeg -i mp4-mkv-input-big.mp4 -vcodec copy -acodec ac3 out.mkv
 }}}
 The output file plays fine here with vlc for two minutes, when does it
 stop for you?
