All DirectShow filters implement this interface. It provides methods for switching the filter between states (stopped, paused, and running); for retrieving the filter's current state; and for setting a reference clock. Applications should not call MediaFilter methods on filters.
The Filter Graph Manager also exposes this interface. Applications can use the SetSyncSource method to set the graph reference clock, and GetSyncSource to retrieve the clock. Applications should not call the other methods on this interface. Instead, use the corresponding methods on the MediaControl interface.
The BaseFilter interface inherits from MediaFilter.
This is an abstract class. You can't create an instance, but you can get one from various plugin functions.
