DXVA2_ExtendedFormat structure (dxva2api.h)
Describes the format of a video stream.
Syntax
typedef struct _DXVA2_ExtendedFormat {
union {
struct {
UINT SampleFormat : 8;
UINT VideoChromaSubsampling : 4;
UINT NominalRange : 3;
UINT VideoTransferMatrix : 3;
UINT VideoLighting : 4;

UINT VideoTransferFunction : 5;
};
UINT value;
};
} DXVA2_ExtendedFormat;
Members
SampleFormat
Describes the interlacing of the video frames. Contains a value from the DXVA2_SampleFormat enumeration.
VideoChromaSubsampling
Describes the chroma siting. Contains a value from the DXVA2_VideoChromaSubSampling enumeration.
NominalRange
Describes the nominal range of the Y'CbCr or RGB color data. Contains a value from the DXVA2_NominalRange enumeration.
VideoTransferMatrix
Describes the transform from Y'PbPr (component video) to studio R'G'B'. Contains a value from the DXVA2_VideoTransferMatrix enumeration.
VideoLighting
Describes the intended viewing conditions. Contains a value from the DXVA2_VideoLighting enumeration.
VideoPrimaries
Describes the color primaries. Contains a value from the DXVA2_VideoPrimaries enumeration.
VideoTransferFunction
Describes the gamma correction transfer function. Contains a value from the DXVA2_VideoTransferFunction enumeration.
value
Use this member to access all of the bits in the union.
Remarks
Most of the values in this structure can be translated directly to and from IMFMediaType attributes. For a code example that fills in the values from an IMFMediaType pointer, see DXVA2_VideoDesc.
