[MPlayer-dev-eng] Speed regression in xvmc since r21209

[Carl Eugen Hoyos]

Hi!

There is a speed regression in mplayer -vo xvmc since r21209 (support for 
dvdnav menu buttons): It makes playing of MPEG2 HD impossible on my Athlon XP 
2600+ (usually consumes ~50% CPU time when using xvmc while watching HD). The 
performance difference is smaller for SD content, but still measurable.

The patch is of course _not_ meant for inclusion, but since I found it 
particularly hard to find the reason (21209 does not compile on linux) for 
the regression, I thought it helps seeing the difference.

I agree that dvdnav is much more important than xvmc but in case somebody 
knows a solution, I'd be happy to test.

Regards, Carl Eugen
