Thx for you interest. 

My first thought was that the wrapper should more or less match one of the
"vendor driver" version or serie, either or not users got the driver from the
Nvidia installer or from repositories (any 3rd part).
That's because the nvidia driver provides the needed vdpau backend for the
vdpau output to work.
But actually the wrapper is rather stable thought time. So my technical concern
about to leave the wrapper in the same repository as the nvidia driver has
left.

Having the wrapper in fedora would allow vdpauinfo (1) and qvdpauinfo (2) to
enter in fedora. Theses tools do not make use of any ffmpeg vdpau codec, so
they are fully usable, (as soon as a vdpau backend driver is there).
They are respectively a glxinfo like tool, and a vdpau benchmark.

What need to be verified for a vdpau enabled player (xine, gstreamer ?) in
Fedora, is that the vdpau ouput isn't used and doesn't produce errors when the
vdpau backend and codec (that live in ffmpeg) aren't available.
Once done, the vdpau wrapper library should behave like any other opensource
library that are redistributed within Fedora, but not fully usable with Fedora
only. (example: the dirac codec was available in fedora before to be used by a
fedora package).

So I'm all in favour to have it discussed in the next FESCo meeting.
