AVPlayerViewController没有显示整个持续时间标签

Question

我面临的问题是，当我尝试播放长时（小时）的远程视频时，AVPlayerViewController时长标签（已过去和剩余）将无法显示整个时长。下面的屏幕快照显示了该问题：

代码：

if let url = URL(string: urlString) {
        let player = AVPlayer(url: url)
        let playerViewController = AVPlayerViewController()

        playerViewController.player = player
        present(playerViewController, animated: true, completion: nil)
        player.play()
    }
