The DXVA_VideoTransferMatrix enumeration type contains enumerators that identify the conversion matrix from Y'Cb'Cr' to R'G'B'.

Constants

`DXVA_VideoTransferMatrixShift`

Specifies to shift bits by 15 positions (DXVA_ExtColorData_ShiftBase + 7, or 8 + 7).

`DXVA_VideoTransferMatrixMask`

Specifies the video transfer matrix mask. 3 (0x00038000) bits of a DWORD can be used to specify video transfer matrix.

`DXVA_VideoTransferMatrix_Unknown`

Specifies that the video transfer matrix is not specified. The default is BT601 for standard definition (SD) video and BT709 for high definition (HD) video.

`DXVA_VideoTransferMatrix_BT709`

Specifies the BT709 transfer matrix.

`DXVA_VideoTransferMatrix_BT601`

Specifies the BT601 transfer matrix.

`DXVA_VideoTransferMatrix_SMPTE240M`

Specifies a HD video standard rarely used in Japan.

Remarks

One of the enumerators of DXVA_VideoTransferMatrix can be specified in the VideoTransferMatrix member of the DXVA_ExtendedFormat structure.
