John, This is looking good - I'm definitely seeing a significant drop in X CPU for some video but not all. It also seems to depend on using mplayer -
When playing a 720x576 vob, I see this: App 'app CPU' 'X CPU' mplayer 15% 35% xine 12% 45% When playing a 688x416 XVID, I see this: xine 14% 25% mplayer 10% 5% Here are the options I'm using: % mplayer -fs -v -monitoraspect 16:9 % xine -f --verbose -r 4:3 Playing a 480 avi gave me very low X CPU usage with mplayer (1-2%) but about 14% under xine. Both apps are using Xv, xdriver 0.10.6 and svn 2757 for these tests. All of this made me wonder about the recommended configuration for use of Xv. John (or others), do you have any such recommendations or should we just figure it out using trial-and-error? Cheers, Wilf.
