将AVPlayerViewController视图添加到外部窗口

Question

我想以编程方式将一个AVPlayerViewController视图从iPad添加到外部窗口。问题在于，添加它时，播放器视图显示＆＃34;此视频正在电视上播放＆＃34;

示例代码：

let player = AVPlayer(url: someUrl)
//these two properties seem to have no effect
//player.usesExternalPlaybackWhileExternalScreenIsActive = true/false
//player.allowsExternalPlayback = true/false
let viewController = AVPlayerViewController()
viewController.player = player
viewController.view.frame = frame
externalWindow.addSubview(viewController.view)
player.play()

有没有办法将自己的视频视图添加到外部窗口，以便我可以决定大小？

Answer 1

如果要控制AVPlayerViewController的大小，可以使用该层，也可以将其添加为childViewController

使用图层

let videoURL = URL(url to your file)
let player = AVPlayer(url: videoURL!)
let playerLayer = AVPlayerLayer(player: player)
playerLayer.frame = self.view.bounds
self.view.layer.addSublayer(playerLayer)
player.play()

在上面的代码中，框架可以根据要求进行调整。

使用ChildViewController：

let videoURL = URL(fileURLWithPath: videoPath)
let player = AVPlayer(url: videoURL)
let playerViewController = AVPlayerViewController()
playerViewController.view.frame = CGRect(give the appropriate size)
playerViewController.player = player  

self.addChildViewController(playerViewController)
self.view.addSubview(playerViewController.view)
playerViewController.didMove(toParentViewController: self)

如果这有帮助，请告诉我！或其他任何需要。
