VMR Windowed Mode with Multiple Streams

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

When the VMR is supplying its own window, it can also be configured for multiple input streams. In this configuration the VMR loads its mixer and compositor to perform the mixing and blending prior to rendering. The application controls the VMR's window manager through the IBasicVideo and IVideoWindow interfaces in the same way as for compatibility mode. The mixer is configured through the IVMRMixerControl interface on the mixer object.
