MFVideoPrimaries Enumeration

Specifies the color primaries of a video source. The color primaries define how to convert colors from RGB color space to CIE XYZ color space.

Syntax

typedef enum _MFVideoPrimaries
{
    MFVideoPrimaries_Unknown = 0,
    MFVideoPrimaries_reserved = 1,
    MFVideoPrimaries_BT709 = 2,
    MFVideoPrimaries_BT470_2_SysM = 3,
    MFVideoPrimaries_BT470_2_SysBG = 4,
    MFVideoPrimaries_SMPTE170M = 5,
    MFVideoPrimaries_SMPTE240M = 6,
    MFVideoPrimaries_EBU3213 = 7,
    MFVideoPrimaries_SMPTE_C = 8,
    MFVideoPrimaries_Last = (MFVideoPrimaries_SMPTE_C+1),
    MFVideoPrimaries_ForceDWORD = 0x7fffffff
} MFVideoPrimaries;

Constants

Constant	Description
MFVideoPrimaries_Unknown	The color primaries are unknown.
MFVideoPrimaries_reserved	Reserved.
MFVideoPrimaries_BT709	ITU-R BT.709. Also used for sRGB and scRGB.
MFVideoPrimaries_BT470_2_SysM	ITU-R BT.470-4 System M (NTSC).
MFVideoPrimaries_BT470_2_SysBG	ITU-R BT.470-4 System B,G (NTSC).
MFVideoPrimaries_SMPTE170M	SMPTE 170M.
MFVideoPrimaries_SMPTE240M	SMPTE 240M.
MFVideoPrimaries_EBU3213	EBU 3213.
MFVideoPrimaries_SMPTE_C	SMPTE C (SMPTE RP 145).
MFVideoPrimaries_Last	Reserved.
MFVideoPrimaries_ForceDWORD	Reserved. This member forces the enumeration type to compile as a DWORD value.

Remarks

This enumeration is used with the MF_MT_VIDEO_PRIMARIES attribute.

For more information about these values, see the remarks for the DXVA2_VideoPrimaries enumeration, which is the DirectX Video Acceleration (DXVA) equivalent of this enumeration.
