Have a look at Task ID 243 on flyspray. The mplayer and mythtv VDPAU packages installed nicely :)

Here's how to do it starting from a functional R6 install:

# pacman -Rd mythtv mplayer nvidia
# pacman -S mythtv-vdpau mplayer-vdpau-nogui
# reboot

Code:
# pacman -Rd mythtv mplayer nvidia

My frontend machine is an old Athlon XP 3200+ (2.2 GHz single core) w/ a PCI 8400 GS I got for $60. The machine without VDPAU is far too slow to playback even a 720p23 h264 file (3,100 Kbps) without VDPAU. CPU usage for mplayer goes to 100 % and play back isn't watchable in the least. When I use cesman's mplayer described in the linked task above, playback is smooth as silk and cpu usage for mplayer averages 2-3 % during playback. VDPAU is truly remarkable. I also used it to watch an OTA 720p60 mpeg file @ 14,800 Kbps and CPU usage was only 5-6 % during playback.

Code:
$ mplayer -fs -zoom -vo vdpau -vc ffh264vdpau /path/to/video/


Related info about vdpau/mplayer
Be sure you check out the mplayer/vdpau docs. There is a slight modification you need to do to the switches, specifically selecting which codec to use.

If you're interested in seeing my GPU temps (idle/load), see this thread.

Running MPlayer:
$ cd mplayer-vdpau
$ ./mplayer -vc <VDPAU-codec-name> -vo vdpau <filename>

'VDPAU-codec-name' can be one of:

ffmpeg12vdpau
ffh264vdpau
ffwmv3vdpau
ffvc1vdpau

based on the type of video bitstream (ffmpeg12vdpau for MPEG-1
or MPEG-2, ffh264vdpau for H.264, ffwmv3vdpau for WMV3, and
ffvc1vdpau for VC-1).

If a VDPAU codec is used, the VDPAU output module must be used.

mplayer-vdpau-nogui is no longer available.
mplayer-vdpau-nogui package not found, searching for group...
error: 'mplayer-vdpau-nogui': not found in sync db

Will mplayer-29134-11 support VDPAU and if not, what do you use?

Thanks
