Full-Screen Video Renderer

This article explains the logic used by the default IVideoWindow plug-in distributor (PID), when an application instructs it to render the video in full-screen mode. Substitute renderer filters can use the IVideoWindow PID for communication with applications. Developers of substitute renderers should be aware of how this PID searches the filter graph for the best means of representing full-screen video, when requested to render in full-screen mode.
