Of course, if it was the case, then we couldn't redistribute anything
compiled with vdpau.
Actually, the library use the same mechanism as XvMC, with an open
source library wrapper exposing the public API.
Then that wrapper will open any vendor vdpau provider library, either
it is open or closed source. In the current situation, the wrapper is
provided as a binary form within the nvidia driver, but can be
packaged from the opensource version also. (cannot remember the url)

It could be possible to have the opensource version packaged in
fedora. But given the problem it will give (API version missmatch,
stability), I wouldn't recommand to do so at this time. Then, one
should notice that dispite the vdpau API is open, there is no
opensource implementation of it yet. (so it could be prevented in
fedora, for that weird reason).
