Update of /cvsroot/mplayer/main/DOCS/man/en
In directory mail:/var2/tmp/cvs-serv12101/DOCS/man/en
Modified Files:
mplayer.1
Log Message:
x264: disable subq=0 (the huge bitrate penalty wasn't worth the speed),
and set default subq to best. wording.
renumber direct_pred (temporal seems to be best)

-Spatial and temporal are approximately the same speed, and neither is
-strictly better than the other.
The best choice depends on the movie.
+Spatial and temporal are approximately the same speed and PSNR,
+but temporal often looks better.
direct_pred=0 is usually both slower and lower quality.

Adjust subpel refinement quality.
This parameter controls quality versus speed tradeoffs involved in the motion
estimation decision process.
It can improve quality significantly.
