IDDrawExclModeVideo interface (strmif.h)

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.


The IDDrawExclModeVideo interface inherits from the IUnknown interface. IDDrawExclModeVideo also has these types of members:


The IDDrawExclModeVideo interface has these methods.


The GetDDrawObject method retrieves the DirectDraw object being used by the Overlay Mixer filter.

The GetDDrawSurface method retrieves the DirectDraw surface being used by the Overlay Mixer.

The GetNativeVideoProps method retrieves the current video size and picture aspect ratio of the Overlay Mixer's primary stream.

The SetCallbackInterface method retrieves a pointer to the callback interface of the Overlay Mixer so that the calling application can be notified about adjustments to the display during video playback.

The SetDDrawObject method sets the DirectDraw object to be used in subsequent drawing.

The SetDDrawSurface method specifies the DirectDraw surface to be used in subsequent drawing.

The SetDrawParameters method specifies which part of the original video will appear at which position of the screen.
