ID3D11VideoContext::VideoProcessorSetStreamDestRect method

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


void VideoProcessorSetStreamDestRect(
  [in]       ID3D11VideoProcessor *pVideoProcessor,
  [in]       UINT                 StreamIndex,
  [in]       BOOL                 Enable,
  [in] const RECT                 *pRect


pVideoProcessor [in]

A pointer to the ID3D11VideoProcessor interface. To get this pointer, call ID3D11VideoDevice::CreateVideoProcessor.

StreamIndex [in]

The zero-based index of the input stream. To get the maximum number of streams, call ID3D11VideoProcessorEnumerator::GetVideoProcessorCaps and check the MaxStreamStates structure member.

Enable [in]

Specifies whether to apply the destination rectangle.

pRect [in]

A pointer to a RECT structure that specifies the destination rectangle. If Enable is FALSE, this parameter is ignored.

Return value

This method does not return a value.


The destination rectangle is the portion of the output surface that receives the blit for this 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 this method is never called, or if the Enable parameter is FALSE, no data is written from this stream.
