Constants
MFNominalRange_UnknownValue: 0 Unknown nominal range. |
MFNominalRange_NormalValue: 1 Equivalent to MFNominalRange_0_255. |
MFNominalRange_WideValue: 2 Equivalent to MFNominalRange_16_235. |
MFNominalRange_0_255Value: 1 The normalized range [0...1] maps to [0...255] for 8-bit samples or [0...1023] for 10-bit samples. |
MFNominalRange_16_235Value: 2 The normalized range [0...1] maps to [16...235] for 8-bit samples or [64...940] for 10-bit samples. |
MFNominalRange_48_208Value: 3 The normalized range [0..1] maps to [48...208] for 8-bit samples or [64...940] for 10-bit samples. |
MFNominalRange_64_127Value: 4 The normalized range [0..1] maps to [64...127] for 8-bit samples or [256...508] for 10-bit samples. This range is used in the xRGB color space. Note Requires Windows 7 or later. |
MFNominalRange_Last |
MFNominalRange_ForceDWORDValue: 0x7fffffff |
Remarks
This enumeration is used with the MF_MT_VIDEO_NOMINAL_RANGE attribute.
For more information about these values, see the remarks for the DXVA2_NominalRange enumeration, which is the DirectX Video Acceleration (DXVA) equivalent of this enumeration.
