Constructs a CBaseControlVideoobject.
CBaseControlVideo( CBaseFilter * pFilter , CCritSec * pInterfaceLock , TCHAR * pName , LPUNKNOWN pUnk , HRESULT * phr );
No return value.
The object implements the IBasicVideocontrol interface.
All the interface methods from IBasicVideothat this class implements require that the filter be connected correctly. For this reason, the class is passed a pin with which it should synchronize with. Whenever an interface method is called, the object determines that the pin is still connected.
