  DXVA_VideoTransferMatrixShift,
  DXVA_VideoTransferMatrixMask,
  DXVA_VideoTransferMatrix_Unknown,
  DXVA_VideoTransferMatrix_BT709,
  DXVA_VideoTransferMatrix_BT601,
  DXVA_VideoTransferMatrix_SMPTE240M
} DXVA_VideoTransferMatrix;

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.
