IMFVideoPresenter interface (evr.h)

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.
