[The feature associated with this page, DirectShow, is a legacy feature. It has been superseded by MediaPlayer, IMFMediaEngine, and Audio/Video Capture in Media Foundation. Those features have been optimized for Windows 10 and Windows 11. Microsoft strongly recommends that new code use MediaPlayer, IMFMediaEngine and Audio/Video Capture in Media Foundation instead of DirectShow, when possible. Microsoft suggests that existing code that uses the legacy APIs be rewritten to use the new APIs if possible.]
The video renderer is switching out of full-screen mode.
Parameters

-
Zero.
-
lParam2
-
(IUnknown*) Pointer to the video renderer's IBaseFilter interface, or NULL.

Remarks
When the Full Screen Renderer loses activation, it sends this event. When another video renderer switches out of full-screen mode, the filter graph manager sends this event, in response to an EC_ACTIVATE event from the renderer.
