  [out]  DXVA2_ProcAmpValues *pValues
);

Parameters

dwFlags [in]

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

pValues [out]

Pointer to a DXVA2_ProcAmpValues structure. The method fills the structure with the current value of each operation specified in dwFlags.

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.

MF_E_TRANSFORM_TYPE_NOT_SET

The media type for the reference stream is not set.

 

Remarks

Before calling this method, you must set the media type for the reference stream.

Until the mixer's video processor mode is set, the returned values are all zero. After the processor mode is set, the returned values reflect the current 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.
