objective-c - AVPlayerLooper 不会循环播放多个视频

Question

我创建了一个 AVPlayerView，用于使用 AVPlayerLooper 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 个视频并在之后循环？

import Cocoa
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()
    }
}
