我使用AVPlayerLooper制作了AVPlayerView，可以不间断播放4个视频。
问题是：AVPlayerLooper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()
}
}
播放所有4个视频并在此之后循环播放？
