Question

我正在AppleTV上播放一个简单的幻灯片。我能够很好地流式传输视频文件并且效果很好，但是当我在本地移动文件（捆绑）时，它无法在实际的AppleTV上播放。但是，它在模拟器上运行良好。

Swift 4.1 Xcode 9.3 带有tvOS 11.3的AppleTV第4代

这是我的代码：

guard let fileURL = Bundle.main.path(forResource: "showroom", ofType:"m4v") else {
        debugPrint("video not found")
        return
    }

    playerAsset = AVAsset (url: URL(fileURLWithPath: fileURL))
    playerItem = AVPlayerItem(asset: playerAsset!)   //(url: fileURL as URL)
    queuePlayer = AVQueuePlayer(items: [playerItem!])
    playerLooper = AVPlayerLooper(player: queuePlayer!, templateItem: playerItem!)


    // Create a new AVPlayerViewController and pass it a reference to the player.
    let controller = AVPlayerViewController()
    controller.player = queuePlayer

    // Modally present the player and call the player's play() method when complete.
    present(controller, animated: true) {
        queuePlayer!.play()
    }

当我在设备上运行时，我收到以下控制台消息，而AppleTV上只有一个带有微调器的空白屏幕：

关于我在这里缺少什么的想法？我也尝试了一个具有相同结果的.MOV文件。谢谢！
