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 It has been superseded by the Simple Video Renderer (SVR) exposed through the MediaPlayer and IMFMediaEngine components.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

Represents a video presenter. A video presenter is an object that receives video frames, typically from a video mixer, and presents them in some way, typically by rendering them to the display. The enhanced video renderer (EVR) provides a default video presenter, and applications can implement custom presenters.

The video presenter receives video frames as soon as they are available from upstream. The video presenter is responsible for presenting frames at the correct time and for synchronizing with the presentation clock.

Inheritance

The IMFVideoPresenter interface inherits from IMFClockStateSink. IMFVideoPresenter also has these types of members:
