Question

AVPlayer图层有时不显示视频内容但播放音频。这种情况有时不会发生这是我的代码行：

 override func viewDidLoad() {
        super.viewDidLoad()
        self.tempVideoPath = NSURL(fileURLWithPath: NSTemporaryDirectory()).appendingPathComponent("tmpMov.mov")
        self.player = AVPlayer(url: self.tempVideoPath!)
}

 override func viewDidAppear(_ animated: Bool) {
     super.viewDidAppear(animated)
     self.playerLayer = AVPlayerLayer(player: self.player)
     self.playerLayer?.frame = self.videoPlayer.bounds
     self.playerLayer?.backgroundColor = UIColor.yellow.cgColor
     self.videoPlayer.layer.addSublayer(playerLayer!)
     print("player = \(playerLayer?.bounds)")

 }

帮我解决这个问题。

您的代码存在的问题是videoPlayer的边界可能会改变。因此，您需要将以下代码添加到视图控制器中，以相应地更改AVPlayerLayer的帧：

override func viewDidLayoutSubviews() {
    super.viewDidLayoutSubviews()

    playerLayer?.frame = view.bounds
}

希望有帮助。
