VideoProcessorSetStreamDestRect function

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

Syntax

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

Parameters

• 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.

Remarks

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.
