我正在使用AVPlayer在Swift中播放本地视频文件(mp4)。有人知道如何检测视频播放完毕的时间吗?谢谢
Answers:
要获取AVPlayerItemDidPlayToEndTimeNotification
您的对象,您需要将其设置为AVPlayerItem
。
为此,只需.currentItem
在您的AVPlayer
现在,一旦视频结束,您将收到通知!
看我的例子:
let videoPlayer = AVPlayer(URL: url)
NSNotificationCenter.defaultCenter().addObserver(self, selector: "playerDidFinishPlaying:",
name: AVPlayerItemDidPlayToEndTimeNotification, object: videoPlayer.currentItem)
func playerDidFinishPlaying(note: NSNotification) {
print("Video Finished")
}
迅捷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")
}
不要忘记删除您的观察者 deinit

NotificationCenter.default.addObserver(self, selector: #selector(playerDidFinishPlaying), name: .AVPlayerItemDidPlayToEndTime, object: nil)
addPeriodicTimeObserver(TimeInterval:)
吗?
object
参数传递currentItem是重要的部分-检查是否有问题。

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")
}
#selector(playerDidFinishPlaying)
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)
}
对于SWIFT 3.0 ,一切正常
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")
}
}

这对我有用。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")
}
斯威夫特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
}
对于SWIFT 3.0
这里的“ fullUrl”是视频的URL,请确保URL中没有空格,您应该将“ Space”替换为“%20”,以便URL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)
}
在视图控制器中的给定方法下面添加此方法。
func playerDidFinishPlaying(){
print("Video Finished playing in style")
}
我知道这里有很多公认的答案...
但是,另一种方法可能是向AVPlayer添加边界时间观察者。您必须拥有视频的时长,可以从中获取视频的时长player.currentItem
,然后将其添加为所需的时间范围。
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
}
