Two guys, one wearing a white shirt and one wearing a gray shirt, are in the street in front of a white van, one motioning towards the camera while the other claps.
Two brothers are filming in the street.
You cannot infer two men are related to each other as brothers.  You cannot infer that men with a camera set up are actually filming anything.
