IAMFilterGraphCallback interface

The IAMFilterGraphCallback interface provides a callback mechanism during graph building.

To use this interface, implement the interface in your application or client object. Query the Filter Graph Manager for the IObjectWithSite interface and call the IObjectWithSite::SetSite method with a pointer to your implementation of the interface. During graph building, if the Filter Graph Manager fails to render a pin, it calls the UnabletoRender method. The client can then take appropriate action, such as providing an error message for the user or registering a new filter.
