IDDrawExclModeVideo interface

The IDDrawExclModeVideo interface enables video playback in DirectDraw exclusive full-screen mode. The Overlay Mixer Filter implements this interface. Game applications can use DirectDraw in exclusive full-screen mode and continue playing video. For example, the video can be in the background and graphics can be used on top of it. The application passes in a DirectDraw object and primary surface, and these are passed to the Overlay Mixer filter in the filter graph.

The DVD graph builder object uses IDDrawExclModeVideo to play DVD content while in DirectDraw exclusive full-screen mode. This interface can also be used alone to play MPEG-1 or AVI videos in games.
