D3D11_1DDI_VIDEO_PROCESSOR_STREAM structure

Contains stream-level data for the VideoProcessorBlt function.

Syntax


typedef struct D3D11_1DDI_VIDEO_PROCESSOR_STREAM {
  BOOL                                Enable;
  UINT                                OutputIndex;
  UINT                                InputFrameOrField;
  UINT                                PastFrames;
  UINT                                FutureFrames;
  D3D11_1DDI_HVIDEOPROCESSORINPUTVIEW *pPastSurfaces;
  D3D11_1DDI_HVIDEOPROCESSORINPUTVIEW hInputSurface;
  D3D11_1DDI_HVIDEOPROCESSORINPUTVIEW *pFutureSurfaces;
  D3D11_1DDI_HVIDEOPROCESSORINPUTVIEW *pPastSurfacesRight;
  D3D11_1DDI_HVIDEOPROCESSORINPUTVIEW hInputSurfaceRight;
  D3D11_1DDI_HVIDEOPROCESSORINPUTVIEW *pFutureSurfacesRight;
} D3D11_1DDI_VIDEO_PROCESSOR_STREAM;

Members

Enable

Specifies whether this input stream is enabled. If the value is TRUE, the VideoProcessorBlt function blits this stream to the output surface. Otherwise, this stream is not blitted.

The maximum number of streams that can be enabled at one time is given in the MaxInputStreams member of the D3D11_1DDI_VIDEO_PROCESSOR_CAPS structure.

OutputIndex

The zero-based index number of the output frame.

InputFrameOrField

The zero-based index number of the input frame or field.

PastFrames

The number of past reference frames.

FutureFrames

The number of future reference frames.

pPastSurfaces

A D3D11_1DDI_HVIDEOPROCESSORINPUTVIEW pointer to an array of pointers, allocated by the caller. This array contains the past reference frames for the video processing operation. The number of elements in the array is equal to PastFrames.

hInputSurface

A D3D11_1DDI_HVIDEOPROCESSORINPUTVIEW pointer to the surface that contains the current input frame.

pFutureSurfaces

A D3D11_1DDI_HVIDEOPROCESSORINPUTVIEW pointer to an array of pointers, allocated by the caller. This array contains the future reference frames for the video processing operation. The number of elements in the array is equal to FutureFrames.

pPastSurfacesRight

If the stereo 3-D format is D3D11_1DDI_VIDEO_PROCESSOR_STEREO_FORMAT_SEPARATE, this member is a D3D11_1DDI_HVIDEOPROCESSORINPUTVIEW pointer to an array of pointers that contains the past reference frames for the right view. The number of elements in the array is equal to PastFrames.

For any other stereo 3-D format, set this member to NULL. For more information, see VideoProcessorSetStreamStereoFormat.

hInputSurfaceRight

If the stereo 3-D format is D3D11_1DDI_VIDEO_PROCESSOR_STEREO_FORMAT_SEPARATE, this member is a D3D11_1DDI_HVIDEOPROCESSORINPUTVIEW pointer to the current input frame for the right view.

For any other stereo 3-D format, set this member to NULL.

pFutureSurfacesRight

If the stereo 3-D format is D3D11_1DDI_VIDEO_PROCESSOR_STEREO_FORMAT_SEPARATE, this member is a D3D11_1DDI_HVIDEOPROCESSORINPUTVIEW pointer to an array of pointers that contains the future reference frames for the right view. The number of elements in the array is equal to FutureFrames.

For any other stereo 3-D format, set this member to NULL.

Remarks

If the stereo 3-D format is D3D11_1DDI_VIDEO_PROCESSOR_STEREO_FORMAT_SEPARATE, the pPastSurfaces, pInputSurface, and pFutureSurfaces members contain the left view.
