[MPlayer-dvb] dvb-t in Norway/NZ

[Håkon Alstadheim]

The mplayer in svn has recently acquired its own version of faad2 to 
decode sound, in the norwegian/nz dvb-t format. Work is in progress but 
there are still issues :-). Anyone who would like to share experiences 
on that, please speak up, or else I'll just lurk here. Just in case 
anyone is listening, here is why I felt the need to post:

As you can see below, simply tuning and decoding seems to be too much 
for my system, even when  dumping both audio and video to dev null. This 
same system has no trouble playing analog tv, and the cpu utilization 
when running the command below is ~10%. "wa" in top is 0.0%. I guess 
I'll go to the -dev list and lurk there a bit, see if i see anyone who 
might appreciate my help in debugging.

           ************************************************
           **** 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.
