ID3D11VideoContext::VideoProcessorGetStreamPixelAspectRatio method

Gets the pixel aspect ratio for an input stream on the video processor.

Syntax


void VideoProcessorGetStreamPixelAspectRatio(
  [in]   ID3D11VideoProcessor *pVideoProcessor,
  [in]   UINT StreamIndex,
  [out]  BOOL *pEnabled,
  [out]  DXGI_RATIONAL *pSourceAspectRatio,
  [out]  DXGI_RATIONAL *pDestinationAspectRatio
);

Parameters

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.

pEnabled [out]

Receives the value TRUE if the pixel aspect ratio is specified. Otherwise, receives the value FALSE.

pSourceAspectRatio [out]

A pointer to a DXGI_RATIONAL structure. If *pEnabled is TRUE, this parameter receives the pixel aspect ratio of the source rectangle.

pDestinationAspectRatio [out]

A pointer to a DXGI_RATIONAL structure. If *pEnabled is TRUE, this parameter receives the pixel aspect ratio of the destination rectangle.

Return value

This method does not return a value.

Remarks

When the method returns, if *pEnabled is TRUE, the pSourceAspectRatio and pDestinationAspectRatio parameters contain the pixel aspect ratios. Otherwise, the default pixel aspect ratio is 1:1 (square pixels).
