[MPlayer-users] Self compiled vs. distribution package - Huge difference

[Peter Lemken]

Howdy,

I'd like to find out, why there is a big difference in performance between my 
self compiled version of mplayer as compared to the distribution package.

I use Mandriva 2008.1, 2.6.24, Xorg 7.3, xf86-video-intel 2.2.1 (and 2.2.903) 
on a Thinkpad T60 with Intel 945 graphics.

package:

rpm -ql mplayer

I was playing around with various xorg settings (EXA vs. XAA) to find the best 
performance in compiz together with video playback, always using my self 
compiled version due to its larger number of codecs. It was only when I tried 
the packaged version that xvideo playback went smoothly both in full screen 
and windowed mode.

The self compiled version eats CPU like mad with -vo x11 and -vo xv is totally 
unusable, yielding 3 fps or so.

Any idea where this difference might have its origin? I'd like to try out -vo 
xvmc with the new intel driver and the packaged version compes without xvmc 
support.

TIA
