DXVAHD_INPUT_FORMAT_CAPS enumeration (dxvahd.h)

  • Article

Defines capabilities related to input formats for a Microsoft DirectX Video Acceleration High Definition (DXVA-HD) device.

Syntax

typedef enum _DXVAHD_INPUT_FORMAT_CAPS {
  DXVAHD_INPUT_FORMAT_CAPS_RGB_INTERLACED = 0x1,
  DXVAHD_INPUT_FORMAT_CAPS_RGB_PROCAMP = 0x2,
  DXVAHD_INPUT_FORMAT_CAPS_RGB_LUMA_KEY = 0x4,
  DXVAHD_INPUT_FORMAT_CAPS_PALETTE_INTERLACED = 0x8
} DXVAHD_INPUT_FORMAT_CAPS;

Constants

 
DXVAHD_INPUT_FORMAT_CAPS_RGB_INTERLACED
Value: 0x1
The device can deinterlace an input stream that contains interlaced RGB video.
DXVAHD_INPUT_FORMAT_CAPS_RGB_PROCAMP
Value: 0x2
The device can perform color adjustment on RGB video.
DXVAHD_INPUT_FORMAT_CAPS_RGB_LUMA_KEY
Value: 0x4
The device can perform luma keying on RGB video.
DXVAHD_INPUT_FORMAT_CAPS_PALETTE_INTERLACED
Value: 0x8
The device can deinterlace input streams with palettized color formats.

Remarks

These flags define video processing capabilities that are usually not needed, and therefore are not required for DXVA-HD devices to support.

The first three flags relate to RGB support for functions that are normally applied to YCbCr video: deinterlacing, color adjustment, and luma keying. A DXVA-HD device that supports these functions for YCbCr is not required to support them for RGB input. Supporting RGB input for these functions is an additional capability, reflected by these constants. The driver might convert the input to another color space, perform the indicated function, and then convert the result back to RGB.

Similarly, a device that supports de-interlacing is not required to support deinterlacing of palettized formats. This capability is indicated by the DXVAHD_INPUT_FORMAT_CAPS_PALETTE_INTERLACED flag.
