Question

非常感谢您提前提供的所有帮助！

有时，AVPlayer无法播放视频，而是显示交叉播放图标。调试起来很困难，因为它只是偶尔发生在不同位置的某些用户。该视频非常适合其他人。文件格式包括.mov和.mp4。

我发现最接近的StackOverflow问题和答案是：iOS AVPlayer showing screen with a cross line on Play icon

我将内容托管在数字海洋空间中。正如以上评论员所指出的那样-它可能链接到慢速网络，并且当AVPlayer没有足够的数据进行缓冲时。在哪里可以找到关于此的更多文档？还是其他人在某些地区的网络连接速度较慢的经验？

func setupVideoPlayback() {
    player?.replaceCurrentItem(with: nil)

    let movieURL = // MY URL
    let asset = AVURLAsset(url: movieURL, options: nil)
    let playerItem = AVPlayerItem(asset: asset)
    player = AVPlayer(playerItem: playerItem)
    player?.automaticallyWaitsToMinimizeStalling = false

    NotificationCenter.default.addObserver(self, selector: #selector(VideoPlayerViewController.playerDidFinishPlaying), name: NSNotification.Name.AVPlayerItemDidPlayToEndTime, object: player?.currentItem)
    NotificationCenter.default.addObserver(self, selector: #selector(VideoPlayerViewController.playerPlaybackStalled), name: NSNotification.Name.AVPlayerItemPlaybackStalled, object: player?.currentItem)
    NotificationCenter.default.addObserver(self, selector: #selector(VideoPlayerViewController.playerSessionRuntimeError), name: NSNotification.Name.AVCaptureSessionRuntimeError, object: player?.currentItem)

    self.player?.play()
}

override func viewDidLoad() {
    super.viewDidLoad()
    let session = AVAudioSession.sharedInstance()
    do {
        try session.setCategory(AVAudioSessionCategoryPlayback, mode: AVAudioSessionModeMoviePlayback, options: [])
        try session.setActive(true)
    } catch {
        print("couldn't switch audio session category")
    }
    setupVideoPlayback()
}

AVPlayer不会偶尔播放视频，而是显示交叉播放图标
