The shots are both from Pirates of the Caribbean 5 trailer.
In the establishing shot - it is showing where the first scene is going to be. A boat is on the sea heading somewhere. This tells the audience that most of the film is going to be filmed on the sea. The ship is old and so that the film is based in olden times.
Over the shoulder shot - this shot shows the captain's face looking at the monkey, the monkey is holding something. They are outside by the ship's wheel. This tells the audience that the monkey has stolen something or he is giving something to the Captain. There are not many places the monkey can go as they are at sea.
