Comment:

 No. DXVA_VideoPrimaries_SMPTE_C is the same as
 DXVA_VideoPrimaries_BT470_2_SysM.

 No. DXVA_VideoPrimaries_EBU3213 is not AVCOL_PRI_EBU3213. It is PAL.
 AVCOL_PRI_EBU3213 has nothing to do with EBU rec. 3213, why it is called
 like this? Well, cause some people are not very clever, it should have
 stayed one of RCA/JEDEC P22 (super)groop of phosphors.

 We do not have DXVA_NominalRange_48_208 or the other even more crazy
 MFNominalRange_64_127. What Micro$oft was thinking about?

 See this patch to see how to set it globally.

 FATE will also need to be fixed.
