IMFVideoProcessor::GetProcAmpValues method (evr9.h)

[The component described on this page, Enhanced Video Renderer, is a legacy feature. It has been superseded by the Simple Video Renderer (SVR) exposed through the MediaPlayer and IMFMediaEngine components. To play video content you should send data into one of these components and allow them to instantiate the new video renderer. These components have been optimized for Windows 10 and Windows 11. Microsoft strongly recommends that new code use MediaPlayer or the lower level IMFMediaEngine APIs to play video media in Windows instead of the EVR, when possible. Microsoft suggests that existing code that uses the legacy APIs be rewritten to use the new APIs if possible.]

Retrieves the current settings for one or more color adjustment (ProcAmp) settings.

Syntax

HRESULT GetProcAmpValues(
  [in]  DWORD               dwFlags,
  [out] DXVA2_ProcAmpValues *Values
);

Parameters

[in] dwFlags

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

[out] Values

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

Return value

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

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.
