    var playerViewController: AVPlayerViewController!
    var player: AVPlayer!


    @objc func buttonTapped() {
        //本地视频
        guard let localVideoURL = Bundle.main.url(forResource: "sample3", withExtension: "mp4") else {
            MyPrint("Invalid URL")
            return
        }
        // 创建AVPlayer
        player = AVPlayer(url: localVideoURL)

        // 创建AVPlayerViewController并设置player
        playerViewController = AVPlayerViewController()
        playerViewController.player = player
        present(playerViewController, animated: true) { [self] in
            player.play()
