DXVADDI_VIDEOPROCESSBLTFLAGS structure (d3dumddi.h)

The DXVADDI_VIDEOPROCESSBLTFLAGS structure identifies changes in the current destination surface from the previous destination surface.

Syntax

typedef struct _DXVADDI_VIDEOPROCESSBLTFLAGS {
  union {
    struct {
      UINT BackgroundChanged : 1;
      UINT TargetRectChanged : 1;
      UINT ColorDataChanged : 1;
      UINT AlphaChanged : 1;
      UINT Reserved : 12;
      UINT DestData : 16;
    };
    UINT Value;
  };
} DXVADDI_VIDEOPROCESSBLTFLAGS;

Members

BackgroundChanged

A UINT value that specifies whether the background color of the destination surface changed. Setting this member is equivalent to setting the first bit of the 32-bit Value member (0x00000001).

TargetRectChanged

A UINT value that specifies whether the target rectangle of the destination surface changed. Setting this member is equivalent to setting the second bit of the 32-bit Value member (0x00000002).

ColorDataChanged

A UINT value that specifies whether format information for the destination surface changed. Setting this member is equivalent to setting the third bit of the 32-bit Value member (0x00000004).

AlphaChanged

A UINT value that specifies whether the planar alpha value for the destination surface changed. Setting this member is equivalent to setting the fourth bit of the 32-bit Value member (0x00000008).

Reserved

This member is reserved and should be set to zero. Setting this member to zero is equivalent to setting the fifth through sixteenth bits (0x0000FFF0) of the 32-bit Value member to zeros.

DestData

A UINT value that contains video processor sample destination data. Setting this member is equivalent to setting the seventeenth through thirty-second bits (0xFFFF0000) of the 32-bit Value member. The following bits can be set:

DXVADDI_DESTDATA_RFF (0x0001)

DXVADDI_DESTDATA_TFF (0x0002)

DXVADDI_DESTDATA_RFF_TFF_PRESENT (0x0004)

Value

A 32-bit value that identifies changes in the current destination surface from the previous destination surface.
