[Libva] [Mesa-dev] nouveau_drv_video.so ?

[Xiang, Haihao]

Are you using VA-API on X11? libva gets the driver name from Xserver,
it is nouveau for you. so libva tries to load nouveau_drv_video.so. 
You can create a symlink for nouveau pointing to a available driver or
just ignore the message because you have gallium_drv_video.so now.

Thanks
Haihao
