Configuring the VMR

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

For all configurations, pins cannot be dynamically added or removed after the VMR is connected to the upstream filter, but they can be connected and disconnected. If the application is unsure how many pins will be needed, it should configure the VMR for the maximum number that might be needed. The presence of unused input pins on the filter does not degrade rendering performance. Unlike the old Overlay Mixer, the VMR has no output pin because it does not require a separate filter for window management.
