Syntax


HRESULT SetProcAmpValues(
  [in]  DWORD dwFlags,
  [in]  DXVA2_ProcAmpValues *pValues
);

Parameters

dwFlags [in]

Bitwise OR of one or more flags, specifying which ProcAmp values to set. For a list of flags, see ProcAmp Settings.

pValues [in]

Pointer to a DXVA2_ProcAmpValues structure. For each flag that you set in dwFlags, set the corresponding structure member to the desired value. To get the valid range of values for each operation, call IMFVideoProcessor::GetProcAmpRange. The method ignores any structure members for which the corresponding flag is not set in dwFlags.

Return value

The method returns an HRESULT. Possible values include, but are not limited to, those in the following table.

Return codeDescription
S_OK

The method succeeded.

E_INVALIDARG

MF_E_TRANSFORM_TYPE_NOT_SET

The media type for the reference stream is not set.

 

Remarks

Before calling this method, set the video processor mode. To select a video processor mode, call IMFVideoProcessor::SetVideoProcessorMode. Otherwise, the EVR automatically selects a mode when streaming begins.

To find out which ProcAmp settings the driver supports, call IMFVideoProcessor::GetVideoProcessorCaps.
