The DXVADDI_VIDEOSAMPLEFLAGS structure identifies changes in the current sample frame from the previous sample frame.
PaletteChangedA 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).
SrcRectChangedA 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).
DstRectChangedA 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).
ColorDataChangedA 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).
PlanarAlphaChangedA 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).
ReservedThis 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.
SampleDataA 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)
ValueA 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.
