Default Re: VDPAU testing tool

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.
