           **** Audio/Video desynchronisation detected! ****
           *************************************************
This means either the audio or the video is played too slowly.
Possible reasons, problems, workarounds:
- Your system is simply too slow for this file.
     Transcode it to a lower bitrate file with tools like HandBrake.
- Broken/buggy _audio_ driver.
     Experiment with different values for --autosync, 30 is a good start.
     If you have PulseAudio, try --ao=alsa .
- Slow video output.
     Try a different -vo driver (-vo help for a list) or try -framedrop!
- Playing a video file with --vo=opengl with higher FPS than the monitor.
     This is due to vsync limiting the framerate.
- Playing from a slow network source.
     Download the file instead.
- Try to find out whether audio or video is causing this by experimenting
  with --no-video and --no-audio.
- If you swiched audio or video tracks, try seeking to force synchronization.
If none of this helps you, file a bug report.
