[MPlayer-users] high CPU load during play of h264 .ts file

[Igor]

Hi

I recorded from satellites HotBird 13E (channel Luxe TV)
http://www.lyngsat.com/hd/hotbird.html
file in h264 ts format

But during playing I have the message about    **** 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 lavdopts,
    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.

I tryed the option -vo null , because I hoped, that with that option cpu-load will be lower, but
unfortunately it's not so.
