Important: I, Robert Massaioli, am not the original author of this tool. But I do maintain it in the hope that it continues to be as useful to other people as it is to me.
This is a little VDPAU benchmarking tool. For example, there are the results on a GT216 :

You will require a Linux install with the following dependencies:
- A basic build environment with C++
- CMake
- qt Dev Tools (like qmake)
- Something that will provide libvdpau.so
This is not an exhaustive list but will highlight some things that you will need.
I wrote a script that will build the code and run it for you. Just open a terminal and type in the following commands:
$ bash -e build_and_run.bash
If this script fails then you are probably missing dependancies. The results will appear once the test is complete.
Important: NVidia users please SET POWERMIZER TO "Maximum Performance" in nvidia-settings.
Let me know if it doesn't work as expected. hftom@free.fr
