I forget the history of this, but why is this not a typedef of an int?

Originally, there was a routing_id here. Since message is changed from routed to
control, the routing_id was gone. But I still keep it as struct in case we need
add more info here. If you are strongly against it, I can use typedef.

-  VideoCaptureControllerID(int device_id);
+  explicit VideoCaptureControllerID(int device_id);
 
   bool operator<(const VideoCaptureControllerID& vc) const;
+  bool operator==(const VideoCaptureControllerID& vc) const;
 
   int device_id;
 };
