swift – AVPlayerLooper不会循环播放多个视频

我使用AVPlayerLooper制作了一个AVPlayerView,可以不间断播放4个视频.

问题是：AVPlayerView只显示一个循环视频.但我需要播放一个序列(4个视频).

如何让AVPlayerLooper播放所有4个视频并在此之后循环播放？

import Cocoa
import AVKit
import AVFoundation

class ViewController: NSViewController {

    @IBOutlet weak var viewOne: AVPlayerView!
    var playerLooper: AVPlayerLooper? = nil

    override func viewDidLoad() {
        super.viewDidLoad()

        let videos = (1...4).map { _ in
            Bundle.main.urls(forResourcesWithExtension: "mov",subdirectory: nil)![Int(arc4random_uniform(UInt32(4)))]
        }

        viewOne.player = AVQueuePlayer(url: videos[Int(arc4random_uniform(UInt32(4)))])
        let item = AVPlayerItem(url: videos[Int(arc4random_uniform(UInt32(4)))])
        playerLooper = AVPlayerLooper(player: viewOne.player as! AVQueuePlayer,templateItem: item)
        viewOne.player?.actionAtItemEnd = .advance
        viewOne.controlsstyle = .none

        NotificationCenter.default.addobserver(self,selector: Selector(("loopSequence")),name: NSNotification.Name.AVPlayerItemDidplayToEndTime,object: viewOne.player?.currentItem)

        func loopSequence() {
            self.viewOne.player?.pause()
            self.viewOne.player?.currentItem?.seek(to: kCMTimeZero,completionHandler: nil)
            self.viewOne.player?.play()
        }
        loopSequence()
    }
}
