            **** Your system is too SLOW to play this!  ****

 Possible reasons, problems, workarounds:
 - Most common: broken/buggy _audio_ driver
   - Try -ao sdl or use the OSS emulation of ALSA.
   - Experiment with different values for -autosync, 30 is a good start.
 - Slow video output
   - Try a different -vo driver (-vo help for a list) or try -framedrop!
 - Slow CPU
   - Don't try to play a big DVD/DivX on a slow CPU! Try some of the
     e.g. -vfm ffmpeg -lavdopts lowres=1:fast:skiploopfilter=all.
 - Broken file
   - Try various combinations of -nobps -ni -forceidx -mc 0.
 - Slow media (NFS/SMB mounts, DVD, VCD etc)
   - Try -cache 8192.
 - Are you using -cache to play a non-interleaved AVI file?
   - Try -nocache.
 Read DOCS/HTML/en/video.html for tuning/speedup tips.
 If none of this helps you, read DOCS/HTML/en/bugreports.html.

 Too many video packets in the buffer: (474 in 33587900 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.
