IMFVideoRenderer interface (evr.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 It has been superseded by the Simple Video Renderer (SVR) exposed through the MediaPlayer and IMFMediaEngine components.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 a new mixer or presenter for the Enhanced Video Renderer (EVR).
Both the EVR media sink and the DirectShow EVR filter implement this interface. To get a pointer to the interface, call QueryInterface on the media sink or the filter. Do not use IMFGetService to get a pointer to this interface.

Methods
