I'm sorry but the license question has never been the problem, as
libvdpau It will behave like libXvMC wrapper library.
Players are expected to link to the open source (MIT) wrapper library
which last will dlopen the appropriate backend library.

Now someone can tell a problem is to have a free implementation of the
vdpau backend library; same as it exist in the XvMC case. So libvdpau
wrapper can be allowed into Fedora. But even then, it will rely on
patented codec (mpeg-2 h264 vc-1) via the the ffmpeg library.
Nevertheless dirac support "may" be in the work and could be added.
Actually a more important problem is that libvdpau still evolve and
might be incompatible with the nvidia binary backend bundled with one
or the other version of a given driver.

So for now it seems better to push for package maintainer of
compatible players to provide an accurate build conditional from the
spec file, so the mplayer can be rebuilt with libdvpau support.
