Question

我有一个自定义视图，其中嵌入了表视图单元格中的AVPlayer。 AVPlayer加载.m3u8链接。但事实是，它在模拟器中工作，但不在物理设备上。关于修复的任何想法？提前谢谢。

class CameraView: UIView {

var player: AVPlayer? {
    get {
        return playerLayer.player
    }
    set {
        playerLayer.player = newValue
    }
}

var playerLayer: AVPlayerLayer {
    return layer as! AVPlayerLayer
}

override static var layerClass: AnyClass {
    return AVPlayerLayer.self
}
private func presentNewStream() {
    let asset = AVAsset(url: URL(string: self.pathToStream)!)
    let keys: [String] = ["playable"]
    asset.loadValuesAsynchronously(forKeys: keys, completionHandler: {
        var error: NSError? = nil
        let status = asset.statusOfValue(forKey: "playable", error: &error)
        switch status {
        case .loaded:
            DispatchQueue.main.async {
                let item = AVPlayerItem(asset: asset)
                self.player = AVPlayer(playerItem: item)
                let playerLayer = AVPlayerLayer(player: self.player)
                playerLayer.videoGravity = AVLayerVideoGravity.resize
                playerLayer.frame = self.bounds
                self.layer.addSublayer(playerLayer)
                self.player?.isMuted = true
            }
            break
        case .failed:
            DispatchQueue.main.async {
                print("failde asset")
                //do something, show alert, put a placeholder image etc.
            }
            break
        case .cancelled:
            DispatchQueue.main.async {
                print("cancelled asset")
                //do something, show alert, put a placeholder image etc.
            }
            break
        default:
            break
        }
    })
}

编辑：在物理设备上进行测试时，我得到了：

}

出现此问题是因为您在本地保存文件的方式正在尝试播放。在您的设备中，您的播放器可能无法访问您的媒体文件。请检查您的网址

此外，尝试使用http url播放服务器上可用的任何媒体文件，看看它是否正常工作。

另外，请确保在服务器的情况下从https提供HLS流。如果您的流网址以http开头，请从您的info.plist文件中允许任意加载。否则它将不会播放任何http流。

{
"_id" : ObjectId("5ad0870d2602ff20497b71b8"),
"Hotel" : {}
}

AVPlayer HLS无法在物理设备上运行
