I have a controller with a AVPlayer in collection view cell. When orientation changes to Landscape, the player should get FullScreen.

For this I am presenting an AVPlayerController with same instance of player in Collection View Cell. The video works fine when it is rotated in playing mode.
However, when video is paused and I change orientation to Landscape, the frame at current moment changes i.e video moves forward.

I have tested, even when the orientation is kept same, when player is passed, the duration skips few seconds.

Here is the code:

In ViewController where cell is present.

override func viewWillTransition(to size: CGSize, with coordinator: UIViewControllerTransitionCoordinator) {

    super.viewWillTransition(to: size, with: coordinator)



    guard let videoCell = contentGalleryController.curatorVideoCell else {return}

    if UIDevice.current.orientation == .landscapeLeft || UIDevice.current.orientation == .landscapeRight {

        let player = videoCell.getVideoPlayer

        playerViewController = (storyboard!.instantiateViewController(withIdentifier: "FullScreenPlayerController") as! FullScreenPlayerController)

        playerViewController?.player = player

        playerViewController?.didPlayedToEnd = videoCell.isVideoFinishedPlaying ?? false

        playerViewController?.isMuteTurnedOn = player.isMuted

        let wasVideoPlaying: Bool = player.isPlaying

        present(playerViewController!, animated: false){

            if wasVideoPlaying {

                player.play()

            }

        }

    }

    else {

        videoCell._setMuteIcon()

        videoCell._setPlayPauseIcon()

        playerViewController?.dismiss(animated: false, completion: nil)

    }

}

In FullscreenPlayer View Controller

override func viewDidLoad() {

        super.viewDidLoad()

        setPlayPauseIcon()

        setMuteIcon()



        let tapGesture = UITapGestureRecognizer(target: self, action: #selector(customControlViewTapped))

        customView.addGestureRecognizer(tapGesture)

    }



    override func viewDidLayoutSubviews() {

        super.viewDidLayoutSubviews()



        if !view.subviews.contains(customView) {

            customView.frame = view.bounds

            view.addSubview(customView)

        }

    }



    override func viewDidAppear(_ animated: Bool) {

        super.viewDidAppear(animated)

        NotificationCenter.default.addObserver(self, selector: #selector(playerDidPlayToEnd), name: Notification.Name.AVPlayerItemDidPlayToEndTime, object: player?.currentItem)

    }



    override func viewDidDisappear(_ animated: Bool) {

        super.viewDidDisappear(animated)

        NotificationCenter.default.removeObserver(self)

    }

I am doing nothing else in controller.

When orientation changes, video moves forward even on pause state.

Thanks for help in advance.

You should try capturing the currentTime and then use the seek(to time: CMTime) method on the player to start at that exact time. I am not sure exactly why this is happening to you, but I think this would get you the result you are looking for.
