Constants

 
DXVADDI_VideoPrimariesMask
Specifies the color primaries mask. The first 5 (0x001F) bits of a DWORD can be used to specify color primaries.
DXVADDI_VideoPrimaries_Unknown
Specifies that color primaries are not specified. The default is BT709.
DXVADDI_VideoPrimaries_reserved
[in] Reserved. Do not use this value.
DXVADDI_VideoPrimaries_BT709
Specifies BT709 primaries (including sRGB and scRGB).
DXVADDI_VideoPrimaries_BT470_2_SysM
Specifies BT470-2 SysM primaries, which are the original NTSC primaries.
DXVADDI_VideoPrimaries_BT470_2_SysBG
Specifies BT470-2 SysBG primaries.
DXVADDI_VideoPrimaries_SMPTE170M
Specifies SMPTE170M primaries, which are rarely used analog NTSC primaries (also known as SMPTE RP 145).
DXVADDI_VideoPrimaries_SMPTE240M
Specifies SMPTE240M primaries.
DXVADDI_VideoPrimaries_EBU3213
Specifies EBU3213 primaries.
DXVADDI_VideoPrimaries_SMPTE_C
Specifies SMPTE_C primaries, which are analog '79 NTSC primaries.
