NSURLErrorDomain错误-1当试图下载http Live流视频

我一直在尝试使用AVAssetDownloadDelegate从网址下载视频。我能够从响应中播放视频，但我无法使用下面的代码下载媒体。NSURLErrorDomain错误-1当试图下载http Live流视频

我收到此错误“的操作无法完成。（NSURLErrorDomain错误-1）”

这是我用

@IBOutlet weak var view1: UIView! 

var configuration : URLSessionConfiguration? = nil 

var downloadSession : AVAssetDownloadURLSession? = nil 

override func viewDidLoad() { 
    super.viewDidLoad() 


     configuration = URLSessionConfiguration.background(withIdentifier: "downloadIdentifier") 


     downloadSession = AVAssetDownloadURLSession(configuration: configuration!, 
                assetDownloadDelegate: self, 
                delegateQueue: nil) 

    let url = URL(string: "http://sample.vodobox.net/skate_phantom_flex_4k/skate_phantom_flex_4k.m3u8") 
    let asset = AVURLAsset(url: url!) 

    let downloadTask = downloadSession?.makeAssetDownloadTask(asset: asset, 
                   assetTitle: "assetTitle", 
                   assetArtworkData: nil, 
                   options: nil) 

    // Start task and begin download 
    downloadTask?.resume() 


    let playerItem = AVPlayerItem(asset: (downloadTask?.urlAsset)!) 
    let player = AVPlayer(playerItem: playerItem) 
    let playerLayer = AVPlayerLayer(player: player) 
    playerLayer.frame = view1.bounds 
    view1.layer.addSublayer(playerLayer) 
    player.play() 


}

此代码是我实现了代表

func urlSession(_ session: URLSession, assetDownloadTask: AVAssetDownloadTask, didFinishDownloadingTo location: URL) { 
    print("Downloaded to Location : \(location)") 
} 



func urlSession(_ session: URLSession, assetDownloadTask: AVAssetDownloadTask, didLoad timeRange: CMTimeRange, totalTimeRangesLoaded loadedTimeRanges: [NSValue], timeRangeExpectedToLoad: CMTimeRange) { 
    var percentComplete = 0.0 
    // Iterate through the loaded time ranges 
    for value in loadedTimeRanges { 
     // Unwrap the CMTimeRange from the NSValue 
     let loadedTimeRange = value.timeRangeValue 
     // Calculate the percentage of the total expected asset duration 
     percentComplete += loadedTimeRange.duration.seconds/timeRangeExpectedToLoad.duration.seconds 
    } 
    print(percentComplete *= 100) 
    // Update UI state: post notification, update KVO state, invoke callback, etc. 
} 

func urlSession(_ session: URLSession, task: URLSessionTask, didCompleteWithError error: Error?) { 


    if (error != nil){ 

     print(error?.localizedDescription) 



    }else{ 

     print("Error") 

    } 

}

请看看这个..

此HLS下载API以许多不同方式破解。几件事你可以尝试：

指定makeAssetDownloadTask调用（选项参数）比特率
修改他们的示例应用来下载视频，这可以帮助你调试看看有什么不对您的播放列表。
实现func urlSession（_ session：URLSession，assetDownloadTask：AVAssetDownloadTask，didResolve resolvedMediaSelection：AVMediaSelection）delegate查看它是否被调用。

嗨@noc，我实现了该函数，并可以看到委托从未被调用。我也指定了比特率，但仍然没有发现变化。我将尝试修改示例应用中的代码，以查看它是否能够正常工作并尽快回复。谢谢 –

哦，我忘了问你了。确保你没有在模拟器上运行。 HLS下载在模拟器上不起作用。 – noc
