[Libva] regression from 1.2: ivybridge + i965/libva=1.3 decodes solid black with mpv --hwdec=vaapi --vo=opengl

[Xiang, Haihao]

Hi, Rinat

Thanks for your patch although I don't think a Depth buffer is needed in
VA GLX.

Hi, Kevin

Could you give a try with Rinat's patch ? It always works for me w/wo
Rinat's patch.

Thanks
Haihao
