VDPAU testing tool

[garyl]

crisalide, your tool is so impressive.
Thank you so much.
Is it possible to add an "H.264 DECODING" test?

AaronP,
> you may need to disable CPU frequency scaling
I did it (see "Cool'n'Quiet OFF"), and the MPEG decoding is improved,
but the MGS4 trailer (H.264) is still slow.

NVIDIA sell 9800/9600GT Low Power for power saving,
so the customers don't want to disable CnQ for them.

Excellent idea. Is it possible to modify sources of this nice tool that it:
- no requires Qt at all
- if Qt is a must - might it be based on Qt3 (I'm on 0.21-fixes which is based on Qt3)
- bulid is based on automake (I want to include to my distro which is based on minimyth)

thx !

Ah, I didn't know that AaronP was a NVIDIA worker.
I could play the MGS4 trailer with AMD 780G by "Media Player Classic Homecinema"
on Windows (with GPU acceleration).
I think the bandwidth is enough.

You shouldn't say "You need to disable CnQ to use 9800'ECO' properly".
That is a bad joke.
I'm very disappointed that the comment came from a NVIDIA developer.

[garyl]

I did a mistake. The Cool'n'Quiet process remained.
I removed the process and run qvdpautest again.

I had managed Cool'n'Quiet by cpufreqd.
I changed it to powernowd and it works better.

You want to run "qmake" or "qmake-qt4".
See README.

crisalide,
> - Added H264 decoding test.
Thank you so much!

I took a movie for checking VDPAU and PowerMizer performances.
http://www.geocities.jp/ep3797/snaps...st20090527.ogg
Get it by wget and play it by mplayer please.

I took the movie by Istanbul.
$ nvidia-settings
=> PowerMizer tab.
$ ./qvdpautest
$ istanbul
=> Right click the Istanbul icon and choose "Select Area to Record"
=> Select Area
=> Left click the Istanbul icon
=> Start qvdpautest

Sometimes PowerMizer chooses a Low Performance Level during the test.
(I disabled Cool'n'Quiet.)
I think the NVIDIA's power calibration is buggy,
so the results of qvdpautest are unstable.

I found the way to play the MGS4 trailer smoothly.

VDPAU improves the CPU usage greatly.
