>+        Remove virtual methods of RealtimeMediaSourceCenter and remove derived classes of it.
>+        Instead port specific implementation directly implement the needed default factory methods.
>+
>+        Renamed some methods for improved consistency.
>+        Moved some static variables as RealtimeMediaSourceCenter members.
