How to solve the problem of UICollectionViewCell reuse causing the video to continue playing

Question

I read the following article:

I am loading videos in AVPlayer in collection view but it repeats some cells data

My attempts:

controller:

    let vidos = ["v1","v2","v3"]

    let collection : UICollectionView = {
        let layout  = UICollectionViewFlowLayout.init()
        layout.scrollDirection = .vertical
        let colle = UICollectionView.init(frame: .zero, collectionViewLayout: layout)
        colle.translatesAutoresizingMaskIntoConstraints = false
        colle.isPagingEnabled = true
        colle.showsVerticalScrollIndicator = false
        return colle
    }()

    override func viewDidLoad() {
        super.viewDidLoad()

        // Do any additional setup after loading the view.
        setUpView()
    }
    func setUpView(){
        collection.delegate = self;
        collection.dataSource = self;
        collection.register(vieosCell.self, forCellWithReuseIdentifier: collId)
        collection.backgroundColor = UIColor.darkGray
        view.addSubview(collection);
        
        collection.snp.makeConstraints { (make) in
            make.top.left.equalTo(view)
            make.bottom.right.equalTo(view)
        }
        
    }

    func collectionView(_ collectionView: UICollectionView, numberOfItemsInSection section: Int) -> Int {
        return vidos.count
    }
    
    func collectionView(_ collectionView: UICollectionView, cellForItemAt indexPath: IndexPath) -> UICollectionViewCell {
        
        let cell = collectionView.dequeueReusableCell(withReuseIdentifier: collId, for: indexPath) as! vieosCell
//        cell.imagSrc = images[indexPath.row]
//        print("111",indexPath.row)
        cell.vido_url = vidos[indexPath.row]
        return cell
    }
    
    
    func collectionView(_ collectionView: UICollectionView, layout collectionViewLayout: UICollectionViewLayout, sizeForItemAt indexPath: IndexPath) -> CGSize {
        return CGSize(width: view.frame.width, height:view.frame.height )
    }
    func collectionView(_ collectionView: UICollectionView, layout collectionViewLayout: UICollectionViewLayout, minimumLineSpacingForSectionAt section: Int) -> CGFloat {
        return 0
    }

cell:

    var vido_url : String?{
        didSet{
            guard let src = vido_url else{
                return
            }
            loadVideo(src)
        }
    }
    
    var player : AVPlayer?
    var plyaerLayer : AVPlayerLayer?
    
    func loadVideo(_ url:String){
        
        guard let path = Bundle.main.path(forResource: url, ofType: "mp4") else {
            return
        }
        player = AVPlayer(url: URL(fileURLWithPath:path))
        plyaerLayer = AVPlayerLayer(player: player)
        plyaerLayer?.frame = contentView.bounds;
        plyaerLayer?.videoGravity = .resizeAspectFill
        contentView.layer.addSublayer(plyaerLayer!)
        player?.play()
    }

    override func prepareForReuse() {
        super.prepareForReuse()
        plyaerLayer?.removeFromSuperlayer()
        player?.pause()

    }

The cell takes up the entire screen, so when I want to switch videos up and down, I want to pause the previous video.

But now when you switch, it continues to play the previous video

Console appears：
