IMFVideoProcessor::SetProcAmpValues 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 It has been superseded by the Simple Video Renderer (SVR) exposed through the MediaPlayer and IMFMediaEngine components.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.]

Sets one or more color adjustment (ProcAmp) settings.

Syntax

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

Parameters

[in] dwFlags

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

[in] pValues

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.

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.
