如何从base64播放视频？

Question

我有一个带有 base64 文件的 JSON 响应（视频）

• 如何将 base64 解码为视频文件？

let data = Data(base64Encoded: base64String!, options: .ignoreUnknownCharacters)
let nsurlItem = NSURL(dataRepresentation: data!, relativeTo: nil)
    do {
           let video = try NSData(contentsOf: nsurlItem as URL, options: .mappedIfSafe) as! NSURL
           let avAsset = AVAsset(url: video as URL)
           let playerItem = AVPlayerItem(asset: avAsset)
           let player = AVPlayer(playerItem: playerItem)
           let playerLayer = AVPlayerLayer(player: player)
           playerLayer.frame = self.view.frame
           self.view.layer.addSublayer(playerLayer)
           player.play()
        } catch {
           print("\nerror", error)
           return
   }

尝试使用init(base64Encoded:options:) NSData 的初始化程序。您可以找到更多信息here。
