 The output file plays very badly with ffplay, it has A/V sync issues with
 vlc, current MPlayer plays no audio, older MPlayer and current MPlayer
 with {{{-demuxer lavf}}} report after ~23 seconds:
 {{{
 Too many video packets in the buffer: (292 in 33638400 bytes).
 Maybe you are playing a non-interleaved stream/file or the codec failed?
 For AVI files, try to force non-interleaved mode with the -ni option.
