如何在 swift 中使用 avplayer 播放来自 ipfs url 的视频

Question

我有一个 ipfs 加密的视频 URL。
我无法在 avplayer 中播放视频，但 URL 在 webview 中播放良好。
这是网址： https: //ipfs.moralis.io:2053 /ipfs/QmUjWnQZVVNmTSVak2QDhTxMkn3dPQozxawa1sm3jE5bLr

let currentURL = URL(string: "https://ipfs.moralis.io:2053/ipfs/QmUjWnQZVVNmTSVak2QDhTxMkn3dPQozxawa1sm3jE5bLr")!
let playerItem = AVPlayerItem(url: currentURL)
playerItem.addObserver(self, forKeyPath: "status", options: NSKeyValueObservingOptions(), context: nil)
player = AVPlayer(playerItem: playerItem)let playerLayer = AVPlayerLayer(player: player)
playerLayer.frame = self.avplayerUIView.bounds
self.avplayerUIView.layer.addSublayer(playerLayer)
player.play()

另外，我已将 AVUrlAssets 与视频扩展和视频编解码器一起使用，但视频仍然无法播放

let mimeType = "video/mp4; codecs=\"avc1.42E01E, mp4a.40.2\""
let asset: AVURLAsset = AVURLAsset(url: videoURL!, options: ["AVURLAssetOutOfBandMIMETypeKey" : mimeType])

奇怪的。好像AVPlayerLayer无法解析视频。如果删除playerLayer，您将听到音频播放正常。

我的解决方案是使用AVPlayerViewController.

let vc = AVPlayerViewController()
vc.view.frame = view.bounds
vc.player = player
player.play()
present(vc, animated: true) // or use as a child view controller by embedding in a container view
