[LateAdopter]

I had tested originally with the wsnipex mesa 10.6.6 first and it had the error, that's why I searched the mesa commits for NV12 and then tried the ~oibaf version.

If you think NV12 should work with a Tusty build, I can try again with a current ~wsnipex Trusty build of fenetmenta-master or I can wait until one appears in the official xbmc-unstable PPA
