This method performs its operation on a separate thread that will not hold any relevant locks. It can be called by a pin or filter to enable renegotiation of the connection. When a transform filter has its input connected, it must agree upon some media type. When the output is connected, it might discover that, to please both its upstream and downstream connections, it would have been better to have chosen a different media type for the upstream connection. The solution is to reconnect the input pin.
Interface Removes a filter from the graph.
