Comment (by ubitux):

 > Playback results with different players:
 > - ffplay: invalid frame rate, playback mostly broken
 > - MPlayer: no video is displayed for a few seconds, and then video
 starts (with -correct-pts the video is freezed for a while)
 > - VLC: samples rate seems insanely high, no video at first, then the
 video starts, and sounds is still way too fast
 > - mplayer2: seems to actually deal with it pretty well
 > Even though mplayer2 seems to handle it, I believe the file is broken
 and something should be fixed.

 Actually I was wrong about mplayer2; the sound is shifted. So no player
 seems to deal well with the output file.
