Syntax

HRESULT VideoProcessorGetStreamExtension(
  [in]        ID3D11VideoProcessor *pVideoProcessor,

  [in]        UINT                 DataSize,
  [out]       void                 *pData
);

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.

pExtensionGuid [in]

A pointer to a GUID that identifies the state. The meaning of this GUID is defined by the graphics driver.

DataSize [in]

The size of the pData buffer, in bytes.

pData [out]
