VideoProcessorSetStreamDestRect function

Sets the destination rectangle for an input stream on the video processor.


VOID APIENTRY* VideoProcessorSetStreamDestRect(
  _In_       D3D10DDI_HDEVICE           hDevice,
  _In_       D3D11_1DDI_HVIDEOPROCESSOR hVideoProcessor,
  _In_       UINT                       StreamIndex,
  _In_       BOOL                       Enable,
  _In_ const RECT                       *pDestRect


hDevice [in]

A handle to the display device (graphics context).

hVideoProcessor [in]

A handle to the video processor object that was created through a call to the CreateVideoProcessor function.

StreamIndex [in]

The zero-based index of the input stream.

Enable [in]

If TRUE, the destination rectangle specified by the pDestRect parameter should be used by the video processor.

pDestRect [in]

A pointer to a RECT structure that specifies the destination rectangle.

Note  If the Enable parameter is FALSE, this parameter is ignored.

Return value

This function does not return a value.


The destination rectangle is the portion of the output surface that receives the bit-block transfer (bitblt) for the specified input stream. The destination rectangle is given in pixel coordinates, relative to the output surface.

The default destination rectangle is an empty rectangle (0, 0, 0, 0). If the VideoProcessorSetStreamDestRect function is never called, or if the Enable parameter is FALSE, no data is written from the specified input stream.
