Configuring for Windowed Mode with a Single Stream

This topic applies to Windows XP Home Edition and Windows XP Professional only.

When the VMR is created it initializes itself by default to windowed mode with a single input stream. This configuration ensures maximum compatibility with existing DirectShow applications. But in order to take advantage of most of the new features provided by the VMR, applications must configure the VMR before it is connected, using the IVMRFilterConfig interface. The application uses the IVideoWindow and IBasicVideo interface methods, obtained from the Filter Graph Manager as with the old Video Renderer, to specify the size and location of the video window.
