How to loop video with AVPlayerLooper

Question

I try to loop a video in a TV OS app with the AVPlayerLooper because this should get rid of the pause/hicup when playing the video again. I watched the WW

Answer 1

I fixed the problem myself.

The playerLooper must be a member variable in the class otherwise it doesn't work because a local variable is gone after the method has been called. So I put this line at the beginning of the class to declare it. I didn't declare it as an AVPlayerLooper because this 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()

        }
    }
}
