Depending on how it was configured mplayer needs (probably)
/etc/X11/XvMCConfig containing /path/to/your/lib/libXvMCr600.so
I add the path "/usr/lib/libXvMCr600.so" to /etc/X11/XvMCConfig, but
mplayer seems not invoke it (No r600 in strace or /proc/pid/maps).
Maybe I should try a newer version of mplayer.
My mplayer reads /usr/lib/XvMCConfig, after I providing that file,
libXvMCr600.so is loaded by mplayer.
Does it work now then?
I don't know how close to rv670 rs780 is, but I have artifact issues
with my rv670 that don't show with my rv790.
If you can get it to display I would interested what -
http://www.andyqos.ukfsn.org/Pendulum.mpg
looks like.
Generally r600 pipe-video still has rendering and functional issues. If you
just want to test fair enough, but if you are trying to make your system
play h264 that it can't currently the best thing you could do is compile svn
mplayer which now has ffmpeg h264 multithread support so -
mplayer -lavdopts threads=4 will use all of your cores.
Tried, not make big difference at first glance. (P.S. can mplayer
show fps in OSD?)
That still doesn't use all CPU power(even with thread=8) according to top.
Just to be clear, this not for pipe video - you have to decode with
ffmpeg software. I guess xv would be the fastest vo to use.
Personally I prefer -vo gl, but gallium is slower than classic for me
(not helped by having a noisy fan requiring me to keep my card on low
power when using as HTPC). I think the difference is because gallium
uses blits rather than memcpy.
I don't think mplayer will show fps, but it does have a benchmark option
(you still have to work out your own fps).
Unless you are bottlenecked on display I expect newmobcal would show a
small difference with threads=4, but some high bitrate h264 would
probably be better.
To benchmark you need to turn off various vsyncs depending on -vo
First in xorg.conf device section
Option "SwapbuffersWait" "off"
For gl, run mplayer with env vblank_mode=0
For xv, xvattr -a XV_VSYNC -v 0
Then try mplayer -nosound -benchmark -vo xv newmobcal1920.ts
and repeat with -lavdopts threads=4
Though it shouldn't affect benchmarks too much, when actually using my
PC as HTPC I've found cpufreq_ondemand to be a pain - so I set to perf.
If rs780 has power saving then that's another variable to play with eg
as root.
echo low > /sys/class/drm/card0/device/power_profile
echo high > /sys/class/drm/card0/device/power_profile
