Question

我正在使用AVPlayer在Swift中播放本地视频文件（mp4）。有没有人知道如何检测视频完成播放？感谢

Answer 1

要使AVPlayerItemDidPlayToEndTimeNotification您的对象成为AVPlayerItem。

为此，只需使用.currentItem

上的 AVPlayer 属性即可

现在，视频结束后您会收到通知！

参见我的例子：

let videoPlayer = AVPlayer(URL: url)       

NSNotificationCenter.defaultCenter().addObserver(self, selector: "playerDidFinishPlaying:",
        name: AVPlayerItemDidPlayToEndTimeNotification, object: videoPlayer.currentItem)

func playerDidFinishPlaying(note: NSNotification) {
    print("Video Finished")
}

Swift 3

let videoPlayer = AVPlayer(URL: url)       

NotificationCenter.default.addObserver(self, selector: Selector(("playerDidFinishPlaying:")), 
       name: NSNotification.Name.AVPlayerItemDidPlayToEndTime, object: videoPlayer.currentItem)

func playerDidFinishPlaying(note: NSNotification) {
    print("Video Finished")
}

不要忘记删除deinit

Swift 3.0

let videoPlayer = AVPlayer(URL: url)

NotificationCenter.default.addObserver(self, selector:#selector(self.playerDidFinishPlaying(note:)),name: NSNotification.Name.AVPlayerItemDidPlayToEndTime, object: player.currentItem)

@objc func playerDidFinishPlaying(note: NSNotification){
        print("Video Finished")
    }

Answer 3

适用于SWIFT 3.0 这工作正常

class PlayVideoViewController: UIViewController {
    override func viewDidLoad() {
        super.viewDidLoad()

        NSNotificationCenter.defaultCenter().addObserver(self, selector: #selector(PlayVideoViewController.finishVideo), name: NSNotification.Name.AVPlayerItemDidPlayToEndTimeNotification, object: nil)
    }

    func finishVideo()
    {
        print("Video Finished")
    }
}

Answer 4

Swift 4.0

这个对我有用。感谢@Channel

    private func playVideo(fileURL: String) {

            // Create RUL object
            let url = URL(string: fileURL)

            // Create Player Item object
            let playerItem: AVPlayerItem = AVPlayerItem(url: url!)
            // Assign Item to Player
            let player = AVPlayer(playerItem: playerItem)

            // Prepare AVPlayerViewController
            let videoPlayer = AVPlayerViewController()
            // Assign Video to AVPlayerViewController
            videoPlayer.player = player

            NotificationCenter.default.addObserver(self, selector: #selector(myViewController.finishVideo), name: NSNotification.Name.AVPlayerItemDidPlayToEndTime, object: nil)

            // Present the AVPlayerViewController
            present(videoPlayer, animated: true, completion: {
                    // Play the Video
                    player.play()
            })

    }

    @objc func finishVideo()
    {
            print("Video Finished")
    }

Answer 5

Swift 4.2版本：

var player: AVPlayer!
  //
  //
// Configure Player
override func viewDidAppear(_ animated: Bool) {
    super.viewDidAppear(animated)

    let filepath: String? = Bundle.main.path(forResource: "selectedFileName", ofType: "mp4")
    if let filepath = filepath {
        let fileURL = URL.init(fileURLWithPath: filepath)
        player = AVPlayer(url: fileURL)
        let playerLayer = AVPlayerLayer(player: player)
        // Register for notification
        NotificationCenter.default.addObserver(self,
                                               selector: #selector(playerItemDidReachEnd),
                                                         name: NSNotification.Name.AVPlayerItemDidPlayToEndTime,
                                                         object: nil) // Add observer

        playerLayer.frame = self.view.bounds
        self.view.layer.addSublayer(playerLayer)
        player.play()
    }
}
// Notification Handling
@objc func playerItemDidReachEnd(notification: NSNotification) {
    player.seek(to: CMTime.zero)
    player.play()
}
// Remove Observer
deinit {
    NotificationCenter.default.removeObserver(self)
}

Answer 6

如果您喜欢使用结合：

private var cancelBag: Set<AnyCancellable> = []

NotificationCenter.default.publisher(for: .AVPlayerItemDidPlayToEndTime)
.sink { _ in
    player.seek(to: CMTime.zero)
    player.play()
}
.store(in: &cancelBag)

Answer 7

Swift 3.0

let videoPlayer = AVPlayer(URL: url)
NotificationCenter.default.addObserver(self, selector:#selector(self.playerDidFinishPlaying(note:)),name: NSNotification.Name.AVPlayerItemDidPlayToEndTime, object: player.currentItem)

func playerDidFinishPlaying(note: NSNotification){
    //Called when player finished playing
}

Answer 8

适用于SWIFT 3.0

此处'fullUrl'是视频的网址，并确保网址中没有空格，您应该将'Space'替换为'％20'，以便网址可以正常工作。

  let videoURL = NSURL(string: fullUrl)
  let player = AVPlayer(url: videoURL! as URL)

  playerViewController.delegate = self
  playerViewController.player = player
  self.present(playerViewController, animated: false) {

    self.playerViewController.player!.play()

    NotificationCenter.default.addObserver(self, selector: #selector(yourViewControllerName.playerDidFinishPlaying), name: Notification.Name.AVPlayerItemDidPlayToEndTime, object: self.player?.currentItem)
  }

在视图控制器中添加以下给定方法。

func playerDidFinishPlaying(){    
print("Video Finished playing in style")
}

Answer 9

在Swift 3和RxSwift 3.5中你所要做的就是：

override func viewDidLoad() {
    super.viewDidLoad()

    NotificationCenter.default.rx.notification(Notification.Name.AVPlayerItemDidPlayToEndTime)
        .asObservable().subscribe(onNext: { [weak self] notification in

            //Your action

        }).addDisposableTo(disposeBag)
}

Answer 10

2019

就这么简单

(addtimes_ a):(list (a-1))

（该对象可以为零。）

然后

    NotificationCenter.default.addObserver(
        self,
        selector: #selector(fileComplete),
        name: NSNotification.Name.AVPlayerItemDidPlayToEndTime,
        object: nil)

Answer 11

我知道这里有很多可接受的答案......

但是，另一条路线可能是将边界时间观察者添加到AVPlayer。您必须拥有视频的持续时间，您可以从player.currentItem获取视频，然后将其添加为所需的时间边界。

fileprivate var videoEndObserver: Any?

func addVideoEndObserver() {
    guard let player = YOUR_VIDEO_PLAYER else { return }

    // This is just in case you are loading a video from a URL.
    guard let duration = player.currentItem?.duration, duration.value != 0 else {
        DispatchQueue.main.asyncAfter(deadline: .now() + 0.5, execute: { [weak self] in
            self?.addVideoEndObserver()
        })

        return
    }

    let endTime = NSValue(time: duration - CMTimeMakeWithSeconds(0.1, duration.timescale))
    videoEndObserver = player.addBoundaryTimeObserver(forTimes: [endTime], queue: .main, using: {
        self.removeVideoEndObserver()

        // DO YOUR STUFF HERE...
    })
}

func removeVideoEndObserver() {
    guard let observer = videoEndObserver else { return }

    videoPlayer.player?.removeTimeObserver(observer)
    videoEndObserver = nil
}

如何检测AVPlayer视频何时结束播放？
