如何檢測AVPlayer視頻何時結束播放？

Question

我使用AVPlayer在Swift中播放本地視頻文件（mp4）。 有沒有人知道如何檢測視頻完成播放？ 謝謝

Answer 1

要得到AVPlayerItemDidPlayToEndTimeNotification您的對象需要是AVPlayerItem。

要做到這一點，只需用你的AVPlayer

的.currentItem財產現在，一旦視頻結束，你會得到一個通知！

見我的例子：

let videoPlayer = AVPlayer(URL: url)  

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

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

斯威夫特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") 
} 

不要忘記取出觀察你deinit

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") 
    }

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 
}

對於SWIFT 3.0

這裏fullUrl'是視頻的網址，並確保有將在URL沒有空間，就應該替換「太空'與'％20'，這樣的URL將工作文件。

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) 
    } 

在您的視圖控制器中添加下面給出的方法。

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

對於SWIFT 3.0 這是工作的罰款

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 6

在斯威夫特3和RxSwift 3.5所有你需要做的是：

override func viewDidLoad() { 
    super.viewDidLoad() 

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

      //Your action 

     }).addDisposableTo(disposeBag) 
}

我知道有很多這裏接受的答案...

Bu t，另一條路線可能是將邊界時間觀察者添加到AVPlayer。您必須獲得視頻的持續時間，您可以從player.currentItem中獲得視頻的持續時間，然後將其添加爲期望的時間範圍。

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 
}

這一個爲我工作。感謝@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") 
    }
