NVIDIA VDPAU Performance Metrics On Ubuntu 14.04 Linux

[pok1yoyo]

Hi.
This is my first post on these forums. First, I would like to say, that I have found many useful information here. Keep up good work.
Now, this may not be exactly the right thread, but I thought it might be appropriate.

I have Asus laptop with optimus, both Intel and nvidia graphic cards. I have Ubuntu 14.04 64bit with 3.13.0-30-generic. No matter what, I cannot seem to manage to get VDPAU to work. I use Intel card most of the time, and I would need nvidia card for watching HD videos with mplayer. This is (for now) the only thing I need it for. I installed bumblebee, which works fine, using nvidia-319 proprietary drivers (probably others too, might even work good with nouveau). Is there someone, who can help me to install VDPAU? I don't care if it means compiling source, switching cards using only command line, installing w/e drivers. I just want to know how to do it. If you have any better solution than VDPAU, that is also great. For now, mplayer uses about 60% of CPU, which I don't like. I believe I need to install libvdpau1 vdpau-va-driver. Anything else? Do I need to configure it somehow?

Some info:

As you can see, both want to use intel's module for vdpau. If do VDPAU_DRIVER=nvidia in from, I get the same error, except with _nvidia instead of _i965.

If you can help me (you can send me PM if you don't want to spam here) or if you need any other information, please say so.

As was already said, it would be useful to test power consumption with software decoding. Test various presentation methods - vdpau (just the presentation part), opengl and xv. The comparison between each of these and hardware decoding would be really nice to see, so we'd have an accurate picture of how useful hardware decoding is. Not necessary to test all those GPUs, just maybe one low-end, one mid-end and one high-end.

Still waiting for passively-cooled Maxwell card...

Ditto. My passively cooled GTS 450 will have to do until then.

I thought that nVidia hardware had a dedicated chip for video processing.

Can we see the power consumption numbers for the open drivers? Intel's is certainly mature, but what about radeon and nouveau?

[Herem]

From a power perspective is 20-30% GPU usage during acceleration worth dropping CPU utilisation by about 6%.

why dont use 340.17 on lastest test, 340.17 launched on 2014.6.9

http://www.nvidia.com/download/driverResults.aspx/76396/en-us

Because this testing was done prior to that driver being out... Since been out in Russia for more than past week, etc.
