I completed my thesis, but there's still work to do on the VP8 CL decoder port to get it up to acceptable performance.

It isn't the most efficient way of doing things (VDPAU state tracker -> libvpx -> OpenCL state tracker -> TGSI), but it would possibly ease the initial development burden, since someone wouldn't also have to bring up a codec-specific video decoder at the same time they do the VDPAU work.
Then, any codecs which have OpenCL/GLSL implementations available could be quickly brought up in st/VDPAU, and in the future pure Gallium versions could be made if performance is an issue.
OK, I'm confused. It looks like there is a 5th X.Org project implementing hardware accelerated VP8 video decoding for Gallium3d using a Gallium3D state tracker which utilises VDPAU - see http://www.google-melange.com/gsoc/o.../gsoc2011/xorg and http://www.google-melange.com/gsoc/p...ricgrange/1001
Have I missed something?

There may still be a lot of work required, but at least the OpenCL state tracker is one of the GSoC projects for this year, which means that at least some work will get done on it.
