DXVAHD_DEVICE_CAPS enumeration (dxvahd.h)

  • Article

Defines video processing capabilities for a Microsoft DirectX Video Acceleration High Definition (DXVA-HD) device.

Syntax

typedef enum _DXVAHD_DEVICE_CAPS {
  DXVAHD_DEVICE_CAPS_LINEAR_SPACE = 0x1,
  DXVAHD_DEVICE_CAPS_xvYCC = 0x2,
  DXVAHD_DEVICE_CAPS_RGB_RANGE_CONVERSION = 0x4,
  DXVAHD_DEVICE_CAPS_YCbCr_MATRIX_CONVERSION = 0x8
} DXVAHD_DEVICE_CAPS;

Constants

 
DXVAHD_DEVICE_CAPS_LINEAR_SPACE
Value: 0x1
The device can blend video content in linear color space. Most video content is gamma corrected, resulting in nonlinear values. If the DXVA-HD device sets this flag, it means the device converts colors to linear space before blending, which produces better results.
DXVAHD_DEVICE_CAPS_xvYCC
Value: 0x2
The device supports the xvYCC color space for YCbCr data.
DXVAHD_DEVICE_CAPS_RGB_RANGE_CONVERSION
Value: 0x4
The device can perform range conversion when the input and output are both RGB but use different color ranges (0-255 or 16-235, for 8-bit RGB).
DXVAHD_DEVICE_CAPS_YCbCr_MATRIX_CONVERSION
Value: 0x8
The device can apply a matrix conversion to YCbCr values when the input and output are both YCbCr. For example, the driver can convert colors from BT.601 to BT.709.
