Hi, I am using the latest Nvidia proprietary drivers on a relatively old
and modest Geforce 8600gt, I have vdpau support compiled only for
Mplayer and Mencoder as far as I can tell (debian-multimedia Squeeze).
mplayer -vo help
will tell you what's available.
If I play an h264 video straight with vlc, xine or Mplayer I can see
clearly my cpu going up and down (c2duo 2.7Ghz), very high throughout,
near 100% on one core and 50% on the other. Video is choppy at time if I
use other programs (namely Icedove, Iceweasel with ±10 tabs, Blender).
If I use :
mplayer -vc ffh264vdpau myvideo
cpu usage is very moderate, stays perfectly flat (about 30%, symmetric
on both cores), and still the video plays perfectly, fluid, even KDE4
desktop effects doesn't make it choppy (sending it to another workspace,
semi-transparency behind another window ...).
So I think I can say that vdpau is working here, but even though it's
compiled in Mplayer it's not used if not explicitly asked for. It should
be put first in Mplayer config file.
Available output modules on my system are ffmpeg12vdpau, ffwmv3vdpau,
ffvc1vdpau and ffh264vdpau.

Happy testing.
