add AVPlayerViewController view to external window - ios

Question

I want to programmatically add an AVPlayerViewController view to an external window from an iPad. The problem is that when adding it, the player view says "This video is playing on the TV"
example code:
let player = AVPlayer(url: someUrl)
//these two properties seem to have no effect
//player.usesExternalPlaybackWhileExternalScreenIsActive = true/false
//player.allowsExternalPlayback = true/false
let viewController = AVPlayerViewController()
viewController.player = player
viewController.view.frame = frame
externalWindow.addSubview(viewController.view)
player.play()
Is there a way to add the video view myself to the external window so I can decide the size?

Answer 1

If you want to control the size of the AVPlayerViewController you can use the layer or you can add it as a childViewController
Using Layer
let videoURL = URL(url to your file)
let player = AVPlayer(url: videoURL!)
let playerLayer = AVPlayerLayer(player: player)
playerLayer.frame = self.view.bounds
self.view.layer.addSublayer(playerLayer)
player.play()
In the above code the frame can be adjusted as per the requirement.
Using ChildViewController:
let videoURL = URL(fileURLWithPath: videoPath)
let player = AVPlayer(url: videoURL)
let playerViewController = AVPlayerViewController()
playerViewController.view.frame = CGRect(give the appropriate size)
playerViewController.player = player
self.addChildViewController(playerViewController)
self.view.addSubview(playerViewController.view)
playerViewController.didMove(toParentViewController: self)
Let me know if this helps!! or anything else is needed.
