I took a different strategy: rather than adjusting the patches to apply
to the version of mplayer we currently have in rpmfusion, I adjusted the
rpmfusion spec to build the version of mplayer which the libva patches
and ffmpeg-mt are happy to work with, if you follow :) Since picking an
mplayer version is a pretty arbitrary sport, and since this stuff is not
likely to land until F13, and since we'll probably want to go with a
later version of mplayer in F13, I don't feel particularly inclined to
spend time porting the libva patches / ffmpeg-mt to play nice with an
older version of mplayer, to be honest. It feels like it'd be wasted
effort.

It's really pretty simple: you just need a later snapshot of mplayer,
and to add libvdpau-devel as a build dependency. Of course, that
requires libvdpau to be packaged, but that's in the course of happening:

All things considered I agree. I'd suggest that, fairly early in the F13
cycle, we bump to a then-current mplayer snapshot, with the libva
patches included. Assuming I've got libva into the repository by then.
My review is waiting on approval:

yeah, I'll keep an eye on it and see how it goes.

BTW, I updated the packages in my repository at the end of last week,
with new versions of libva and mplayer-accelerated, since Gwenole
released new versions of those. The changes mostly concern the OpenGL
interface for the vaapi stuff. If you define my repository and do
regular yum updates you should get the new versions automatically, of
course.
