AVPlayerViewController controls disappear

I'm working on an iPad only app that has a UIPageViewController. One of the pages is supposed to show an mp4 video using an AVPlayerViewController as the page view controller. When the video is initially displayed there is a triangle in a circle icon in the center of the screen. When it is tapped the video starts playing . So far so good. Then the standard set of video controls appears - and then disappears in 2 seconds. Tapping on the video view brings them back - for another two seconds.

Is there any way to set the timeout or some other trick that will keep them around for the normal period of time?
