I'm working with AVPlayerto show the playing video using a URL in it. There are 2 parts to it:

1. Firstly, I've embedded the AVPlayer to a view's sublayer using AVPlayerLayer, i.e.

var player: AVPlayer?



func configure() {

    let urlString = "https://clips.vorwaerts-gmbh.de/big_buck_bunny.mp4"

    if let url = URL(string: urlString) {

        self.player = AVPlayer(url: url)

        let playerLayer = AVPlayerLayer(player: self.player)

        playerLayer.frame = self.view.bounds

        self.view.layer.addSublayer(playerLayer)

        player.play()

    }

}

The above code is working fine and the video is playing.

2. Secondly, on a UIButton tap, I'm presenting a AVPlayerViewController using the same AVPlayer instance that I created earlier, i.e.

@IBAction func onTapVideoButton(_ sender: UIButton) {

    self.player?.pause()

    let controller = AVPlayerViewController()

    controller.player = self.player

    self.present(controller, animated: true) {

        self.player?.play()



    }

}

The problem I'm facing here is, after the AVPlayerViewController opens, the video stops playing but the audio still plays on.

What I want is to sync the video in both AVPlayerLayer and AVPlayerViewController.

I think there is a problem when sharing a player already created to the AVPlayerViewController. I'm not sure why is stoping but it wont happen if you create a new AVPlayer for that controller. A way to sync your player and your AVPlayerViewController could be like this:

First, you create a Notification Name that you'll use when the AVPlayerViewController is dismiss (apple does not give you a way to know when the user dismiss the AVPlayerViewController):

extension Notification.Name {

    static let avPlayerDidDismiss = Notification.Name("avPlayerDidDismiss")

}

Then, you extend AVPlayerViewController to post this notification when is going to be dismiss and to send the time when the user left the video:

extension AVPlayerViewController {



    open override func viewWillDisappear(_ animated: Bool) {

        super.viewWillDisappear(animated)

        if let seekTime = player?.currentTime() {

            let userInfo = ["seekTime": seekTime]

            NotificationCenter.default.post(name: .avPlayerDidDismiss, object: nil, userInfo: userInfo)

        }

    }



}

And in your ViewController you observe that notification, get the seekTime you want to go and use it to setup your avPlayer:

class ViewController: UIViewController {

    var player: AVPlayer?



    deinit {

        NotificationCenter.default.removeObserver(self)

    }



    override func viewDidLoad() {

        super.viewDidLoad()

        configure()

        NotificationCenter.default.addObserver(self, selector: #selector(avPlayerDidDismiss), name: .avPlayerDidDismiss, object: nil)

    }



    func configure() {

        self.player = getPlayer()

        let playerLayer = AVPlayerLayer(player: self.player)

        playerLayer.frame = self.view.bounds

        self.view.layer.addSublayer(playerLayer)

        self.player?.play()

    }



    @IBAction func onTapVideoButton(_ sender: UIButton) {

        self.player?.pause()

        let controllerPlayer = getPlayer()

        controllerPlayer.currentItem?.seek(to: self.player!.currentTime(), completionHandler: nil)

        let controller = AVPlayerViewController()

        controller.player = controllerPlayer

        self.present(controller, animated: true, completion: {

            controller.player?.play()

        })

    }



    func getPlayer() -> AVPlayer {

        let url = URL(string: "https://clips.vorwaerts-gmbh.de/big_buck_bunny.mp4")!

        return AVPlayer(url: url)

    }



    @objc

    private func avPlayerDidDismiss(_ notification: Notification) {

        if let seekTime = notification.userInfo?["seekTime"] as? CMTime {

            player?.currentItem?.seek(to: seekTime, completionHandler: nil)

            player?.play()

        }

    }

}

Cons: It will send the notification for every AVPlayerViewController. You use add you as an observer when you need this info. Hope it can help.
