Do you have commit access? And by the way I have enough on my to do list
for the VDPAU state tracker if you're bored.
I do not have commit access, so please feel free to push if things look
good. Bug in the nouveau vdpau driver hinted me to look this way,
although I would not mind doing a few more things when I have some time
(after 27 August).
Patches are committed, thanks for the help.
I have a something like 50% done implementation of NV_vdpau_interop, but
no time to finish it. The patch can be found here:
http://cgit.freedesktop.org/~deathsimple/mesa/commit/?id=39f64342ca6400fb4bf163232848c23e0a192b92
If you want to work on something I suggest to start with implementing
some piglit tests for VDPAU interop which should work with the NVidia
binary driver.
An alternative is to dig into advanced deinterlacing, something like
YADIF (https://trac.handbrake.fr/wiki/yadif) in shaders for example.
Cheers,
Christian.
