XCDYouTubeClient 不在 Swift 4 中播放视频

Question

我正在尝试通过 XCDYouTubeClient 库播放 youtube 视频，但它不播放视频。我还参考了文档，但它没有帮助我解决问题

let playerViewController = AVPlayerViewController()
self.present(playerViewController, animated: true, completion: nil)

XCDYouTubeClient.default().getVideoWithIdentifier("tG7vx7-3sl0") { [weak playerViewController] (video: XCDYouTubeVideo?, error: Error?) in
      if let streamURLs = video?.streamURLs, let streamURL = (streamURLs[XCDYouTubeVideoQualityHTTPLiveStreaming] ?? streamURLs[XCDYouTubeVideoQuality.HD720] ?? streamURLs[XCDYouTubeVideoQuality.medium360] ?? streamURLs[XCDYouTubeVideoQuality.small240]) {
           playerViewController?.player = AVPlayer(url: streamURL)
      } else {
           self.dismiss(animated: true, completion: nil)
       }
}

谢谢

您可以使用以下代码。一些 youtube 链接没有XCDYouTubeVideoQuality.HD720 视频质量。只需将其移除，视频就会开始播放。

XCDYouTubeClient.default().getVideoWithIdentifier("tG7vx7-3sl0") { [weak self] (video, error) in

   if video != nil {
     var streamURLs = video?.streamURLs
     let streamURL = streamURLs?[XCDYouTubeVideoQualityHTTPLiveStreaming] ?? streamURLs?[NSNumber(value: XCDYouTubeVideoQuality.medium360.rawValue)] ?? streamURLs?[NSNumber(value: XCDYouTubeVideoQuality.small240.rawValue)]
     if let streamURL = streamURL {
         playerViewController?.player = AVPlayer(url: streamURL)
     }
     playerViewController?.player?.play()

   } else {
      self?.dismiss(animated: true)
   } 
}
