Comment 6 for bug 993397

Hi, Doug McMahon,

Actually on my machine mlayer is using 50%-70% of cpu and Compiz uses about 15%. If disable sync to vbank then for movies not maximized cpu usage for mplayer is on single digit and Compiz about 5-6%, consistent with 11.04 under vdpau on the same machine.

After further trial and errors it appears that vdpau works perfectly in XBMC if 'undirect fullscreen windows' is checked in ccsm (cpu usage in single digit for full screen) but it still doesn't work for mplayer or mplayer2 (tried different versions from official repo, different ppas and compiling myself)

It seems that it is definitely a Compiz bug, I am surprised that not more people are affected. However there are several apparently related bugs filed against Compiz/Unity 3d and the Nvidia driver, it may be that this bug is just another manifestation of the same underlying issue.

I hope this get fixed soon. I really like Unity in 12.04 but having to log into a different Desktop to watch movie or use xv in Unity while I have a Nvidia card is just nonsensical. I will have to use Gnome Shell until this is fixed.
