How to connect video using AVPlayerLooper

Question

I am trying to loop a video in a TV OS application using AVPlayerLooper , because this should get rid of the pause / hicup when playing the video again. I watched the WWDC2016 video https://developer.apple.com/videos/play/wwdc2016/503/ and tried to implement the code, but it doesn't loop. I have one PlayerViewController that inherits AVPlayerViewController . I put the code in the video loop. If I have the following code, it shows nothing. If I change the second line to self.queuePlayer = AVQueuePlayer(playerItem:playerItem) , it will only play once.

  let playerItem = AVPlayerItem(url: url as URL) self.queuePlayer = AVQueuePlayer() //I declared this as a variable in the view controller self.playerLayer = AVPlayerLayer(player: self.queuePlayer) //I declared this as a variable in the view controller let playerLooper = AVPlayerLooper(player: self.queuePlayer!, templateItem: playerItem) self.view.layer.addSublayer(self.playerLayer!) self.playerLayer?.frame = self.view.frame self.queuePlayer?.play() 

Have any of you managed to play a looped video with the latest AVPlayerLooper ?

I fixed the problem myself.

PlayerLooper must be a member variable in the class, otherwise it will not work, because after calling the method the local variable will disappear. So I put this line at the beginning of the class to declare it. I did not declare it as AVPlayerLooper, because it is only for tvos10.0 and newer versions. I want my class to be adaptive to tvos9.0. This is my working code.

 var playerLooper: NSObject? var playerLayer:AVPlayerLayer! var queuePlayer: AVQueuePlayer? func playVideo(_ filmName: String){ if let path = Bundle.main.path(forResource: filmName, ofType: "mov") { let url = URL(fileURLWithPath: path) if #available(tvOS 10.0, *) { // Use a new player looper with the queue player and template item let playerItem = AVPlayerItem(url: url as URL) self.player = AVQueuePlayer(items: [playerItem]) self.playerLayer = AVPlayerLayer(player: self.player) self.playerLooper = AVPlayerLooper(player: self.player! as! AVQueuePlayer, templateItem: playerItem) self.view.layer.addSublayer(self.playerLayer!) self.playerLayer?.frame = self.view.frame self.player?.play() } else { // Fallback on earlier versions, this solution has hicup at end player = AVPlayer(url: url) player?.play() loopVideo(player!) } } } func loopVideo(_ videoPlayer: AVPlayer) { NotificationCenter.default.addObserver(forName: NSNotification.Name.AVPlayerItemDidPlayToEndTime, object: nil, queue: nil) { notification in if(!self.isStopped){ videoPlayer.seek(to: kCMTimeZero) videoPlayer.play() } } }
