DXVADDI_VIDEOSAMPLEFLAGS structure (d3dumddi.h)

The DXVADDI_VIDEOSAMPLEFLAGS structure identifies changes in the current sample frame from the previous sample frame.

Syntax

typedef struct _DXVADDI_VIDEOSAMPLEFLAGS {
  union {
    struct {
      UINT PaletteChanged : 1;
      UINT SrcRectChanged : 1;
      UINT DstRectChanged : 1;
      UINT ColorDataChanged : 1;
      UINT PlanarAlphaChanged : 1;
      UINT Reserved : 11;
      UINT SampleData : 16;
    };
    UINT Value;
  };
} DXVADDI_VIDEOSAMPLEFLAGS;

Members

PaletteChanged

A UINT value that specifies whether the palette of the sample frame changed. Setting this member is equivalent to setting the first bit of the 32-bit Value member (0x00000001).

SrcRectChanged

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

DstRectChanged

A UINT value that specifies whether the destination rectangle of the sample frame changed. Setting this member is equivalent to setting the third bit of the 32-bit Value member (0x00000004).

ColorDataChanged

A UINT value that specifies whether the color data of the sample frame changed. Setting this member is equivalent to setting the fourth bit of the 32-bit Value member (0x00000008).

PlanarAlphaChanged

A UINT value that specifies whether the alpha (transparency) data of the sample frame 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 sixth through sixteenth bits (0x0000FFE0) of the 32-bit Value member to zeros.

SampleData

A UINT value that contains video sample 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_SAMPLEDATA_RFF (0x0001)

DXVADDI_SAMPLEDATA_TFF (0x0002)

DXVADDI_SAMPLEDATA_RFF_TFF_PRESENT (0x0004)

Value

A member in the union that is contained in DXVADDI_VIDEOSAMPLEFLAGS that can hold one 32-bit value that identifies changes in the current sample frame from the previous sample frame.
