DXVA_VideoSample32 structure (dxva.h)
The DXVA_VideoSample32 structure is used for forwarding 32-bit DXVA_DeinterlaceBltEx calls on 64-bit drivers.
Syntax
typedef struct _DXVA_VideoSample32 {
REFERENCE_TIME rtStart;
REFERENCE_TIME rtEnd;
DWORD SampleFormat;
DWORD SampleFlags;
DWORD lpDDSSrcSurface;
RECT rcSrc;
RECT rcDst;
DXVA_AYUVsample2 Palette[16];
} DXVA_VideoSample32;
Members
rtStart
Specifies the start time of the sample.
rtEnd
Specifies the end time of the sample.
SampleFormat
Specifies the format of the sample as defined by values of the DXVA_ExtendedFormat enumeration type.
SampleFlags
Specifies a collection of flags that indicate changes in the current sample frame from the previous sample frame. This member is a bitwise-OR of one or more of the flags in the DXVA_SampleFlags enumeration type.
lpDDSSrcSurface
Pointer to a DD_SURFACE_LOCAL structure that represents the sample.
rcSrc
Specifies a RECT structure that describes the upper-left and lower-right points of a rectangle on the source surface. These points define the area of the source data for the bit-block transfer and its position on the source surface.
rcDst
Specifies a RECT structure that describes the upper-left and lower-right points of a rectangle on the destination surface. These points define the area in which the bit-block transfer should occur and its position on the destination surface.
Palette[16]
Specifies an array of DXVA_AYUVsample2 structures that represent a complete 16-color palette for palletized video substream pixel formats. The driver uses this palette to composite the substream sample. For nonpalletized pixel formats, the palette is zero and can be ignored.
Remarks
The compiler adds 4 bytes of padding to align the structure to 8 bytes.
