The SetControlVideoPin method sets the pin used by the filter.
void SetControlVideoPin( CBasePin *pPin );
Pointer to the pin with which the interface is synchronized.
No return value.
The interface can be called only when the filter has been connected successfully. The object is passed through this method to the pin with which it is synchronized; in most cases it will determine if the pin is connected when it has an interface method called and will return VFW_E_NOT_CONNECTED if it fails.
