Public bug reported:
vdpau works very poorly in Ubuntu 12.04 LTS on Unity3d. Same 1080p
movies use around 6-10% of cpu in 11.04 and 11.10 shoots up to 50-60% of
cpu usage in 12.04 with vdpau and mplayer (all under Unity 3d) . I have
tried several nvidia drivers and the results are the same
Hi guys,
I have filed a bug report on the Nvidia driver and Unity 3d concerning
vdpau. I have downgraded to 295.20 and the problem of poor vdpau
performance still persists. If any of you are having the same issue
please add an 'affect me too'. Thanks.
Hello,
I have created a bug report on Unity3d and the Nvidia drivers concerning
vdpau in Precise. I am not sure if it is related to this bug.

I have downgraded to 295.20 and it didn't make a difference. No problem
in
Just upgraded the Nvidia driver to 302.07 (via xorg-edgers) Still the
same, vdpau works perfectly in Gnome Shell but only semi working Unity
3d (without vdpau CPU usage ~100%, with vdpau cpu usage ~ 50-60% in
Unity 3d, 6-10% in Gnome Shell,--and Unity3d for 11.04 and 11.10)
It seems that

I also notice watching video with vdpau consumes abnormally high cpu
usage. For the same video, in Natty the cpu usage using mplayer2 with
vdpau (Nvidia295.20) is somewhere between 5 to 15%, in Precise it is
around 50% even though vdpau is enabled (I know it is enabled aside from
terminal output
I am also using the xorg-edgers ppa in Oneric (32bit) and I get the same
error trying to start ccsm so this is probably not a ubuntuone bug.
