Thread 1: "Application tried to present modally a view controller <AVPlayerViewController: 0x15f83ee00> that has a parent view controller <ValorantAgentsApp.AbilitiesDetailsViewController: 0x15e918670>."
I get error when tried to play video in my app. My application crashes when it comes to the screen where I will play a video. I don't have a problem when I play the video with by pressing a button. But when I want to play as the screen loads, I get a crash.

let controller = AVPlayerViewController()
present(controller, animated: true) { }
controller.player = player
addChild(controller)
view.addSubview(controller.view)
controller.view.frame = CGRect(x: 50 , y: 50, width: 300, height: 300)
controller.player = player
controller.showsPlaybackControls = true
player.isClosedCaptionDisplayEnabled = false
player.play()

}
let player = AVPlayer(url: videoURL)
let vc = AVPlayerViewController()
vc.player = player
present(vc, animated: true) {
player.play()
}
}

}
This is my third screen and view controller.
either do:
view.addSubview(controller.view)
OR
present(controller, animated: true) { }
not both
I have programmatically added an AVPlayerViewController to a UIViewController. I am able to receive the notification when the player is finished playing (playerDidFinishPlaying). I would also like to know if a user has touched the screen while the video is playing and I have not found any related notifications.
The solution is to create a Base class of AVPlayerViewController and override touchesBegan(_:with:) method:
Swift 2:
Custom Base Class:
class CustomAVPlayerViewController: AVPlayerViewController {
override func touchesBegan(touches: Set<UITouch>, withEvent event: UIEvent?) {
print("touchesBegan")
}
}
ViewController:
let videoURL = NSURL(string: "https://clips.vorwaerts-gmbh.de/big_buck_bunny.mp4")
let player = AVPlayer(URL: videoURL!)
let playerViewController = CustomAVPlayerViewController()
playerViewController.player = player
self.presentViewController(playerViewController, animated: true) {
playerViewController.player!.play()
}
Swift 3:
Custom Base Class:
class CustomAVPlayerViewController: AVPlayerViewController {
override func touchesBegan(_ touches: Set<UITouch>, with event: UIEvent?) {
print("touchesBegan")
}
}
View Controller:
let videoURL = URL(string: "https://clips.vorwaerts-gmbh.de/big_buck_bunny.mp4")
let player = AVPlayer(url: videoURL!)
let playerViewController = CustomAVPlayerViewController()
playerViewController.player = player
self.present(playerViewController, animated: true) {
playerViewController.player!.play()
}
Don't forget to import AVKit and import AVFoundation.
Each time you tap on the playerViewController, "touchesBegan" will be printed.
I had this same problem. The contentOverlayView is only available in tvos, so that was not an option.
I ended up adding a UIView over the UIImageView that I added the AVPlayer to. I set the background color to clear on the UIView, so it's not visible, but can receive gestures. This provides a target for the tap gesture recognizer.
I resolve the same. Subclassing AVPlayerViewController will work on iOS 11.4.1 but not on iOS 12 an above. So the solution for this is add subview on playerviewcontroller contentoverlayview and then on that subview you can add any gesture or button for detecting the touch. Here is the code snippet for the same::
// This notification is added for continuous playing of the video you can remove this in case you need video is played only once.
private func playVideo() {
guard let path = Bundle.main.path(forResource: "BG01", ofType:"mp4") else {
debugPrint("video.m4v not found")
return
}
self.player = AVPlayer(url: URL(fileURLWithPath: path))
NotificationCenter.default.addObserver(forName: .AVPlayerItemDidPlayToEndTime, object: self.player?.currentItem, queue: .main) { [weak self] _ in
self?.player?.seek(to: kCMTimeZero)
self?.player?.play()
}
let playerController : AVPlayerViewController? = AVPlayerViewController()
let btn : UIButton = UIButton()
btn.frame = CGRect(x: 0, y: 0, width: self.view.frame.size.width, height: self.view.frame.size.height)
btn.addTarget(self, action: #selector(touchDetect), for: .touchUpInside)
btn.backgroundColor = UIColor.clear
playerController?.contentOverlayView?.addSubview(btn)
// playerController?.homeVCProtocolDelegate = self as HomeVCProtocol
playerController?.player = player
playerController?.showsPlaybackControls = false
self.player?.play()
present(playerController!, animated: false) {
self.player?.play()
}
}
#objc func touchDetect()
{
// Here you will get the call
}
I using AVPlayerViewController which I want to fadeout when the video ends... I can capture the end-of-video event, and I the code put together for AVPlayer works, but for the AVPlayerViewController not.
self.playerItem = AVPlayerItem(URL: videoURL)
self.player = AVPlayer(playerItem: self.playerItem)
self.playerLayer = AVPlayerLayer(player: self.player)
self.streamPlayer = AVPlayerViewController()
self.streamPlayer.player = self.player
self.streamPlayer.view.frame = CGRect(x: 128, y: 222, width: 512, height: 256)
This code works too, but goes full screen- I don't want full screen...
//self.presentViewController(self.streamPlayer, animated: true) {
// self.streamPlayer.player!.play()
//}
I use this?
self.view.addSubview(self.streamPlayer.view)
self.streamPlayer.player!.play()
The event capture ..
override func viewWillAppear(animated: Bool) {
NSNotificationCenter.defaultCenter().addObserver(self, selector: "finishedPlaying:", name: AVPlayerItemDidPlayToEndTimeNotification, object: playerItem)
}
The event Code ...
func finishedPlaying(myNotification:NSNotification) {
let fadeOut = CABasicAnimation(keyPath: "opacity")
fadeOut.fromValue = 1.0
fadeOut.toValue = 0.0
fadeOut.duration = 8.0
fadeOut.delegate = self
fadeOut.setValue("video", forKey:"fadeOut")
fadeOut.removedOnCompletion = false
fadeOut.fillMode = kCAFillModeForwards
This line does nothing with AVPlayerViewController/With AVPlayer it fades out nicely ?
playerLayer.addAnimation(fadeOut, forKey: nil)
This simply removes AVPlayerViewController, plan B if I cannot make this work!
//self.streamPlayer.view.removeFromSuperview()
print("VIDEO finished")
}
AVPlayerViewController has it's own AVPlayerLayer and does not know about the AVPlayerLayer you created. Thus, the line
playerLayer.addAnimation(fadeOut, forKey: nil)
has no effect. You should set or animate the alpha value of AVPlayerViewController's view. For the fade animation you may want to look at the +[UIView animateWithDuration:(...)] methods and call
self.streamPlayer.view.removeFromSuperview()
in the completion handler.
So I have a video playing in the background and two button images that fade in. Both work fine, however on the simulator when I launch the app, I see the button images on the white screen then it goes into playing the video and the animation. I also have the alpha set to 0 in the main story board on each image. Not sure if this is a simulator/launch screen glitch or my code. My code is below and any help is appreciated. Thanks!
import UIKit
import Parse
import MediaPlayer
class ViewController: UIViewController {
#IBOutlet var loginAlpha: UIButton!
#IBOutlet var signupAlpha: UIButton!
var avPlayer: AVPlayer!
var avPlayerLayer: AVPlayerLayer!
var paused: Bool = false
override func viewDidLoad() {
super.viewDidLoad()
// code for background video
let theURL = NSBundle.mainBundle().URLForResource("test", withExtension: "mp4")
avPlayer = AVPlayer(URL: theURL!)
avPlayerLayer = AVPlayerLayer(player: avPlayer)
avPlayerLayer.videoGravity = AVLayerVideoGravityResizeAspectFill
avPlayer.volume = 0
avPlayer.actionAtItemEnd = AVPlayerActionAtItemEnd.None
avPlayerLayer.frame = view.layer.bounds
view.backgroundColor = UIColor.clearColor();
view.layer.insertSublayer(avPlayerLayer, atIndex: 0)
NSNotificationCenter.defaultCenter().addObserver(self,
selector: "playerItemDidReachEnd:",
name: AVPlayerItemDidPlayToEndTimeNotification,
object: avPlayer.currentItem)
}
func playerItemDidReachEnd(notification: NSNotification) {
let p: AVPlayerItem = notification.object as! AVPlayerItem
p.seekToTime(kCMTimeZero)
}
override func viewDidAppear(animated: Bool) {
signupAlpha.alpha = 0
loginAlpha.alpha = 0
UIView.animateWithDuration(1.5, delay: 1.0, options: [], animations: { () -> Void in
self.signupAlpha.alpha = 1.0
self.loginAlpha.alpha = 1.0
}, completion: nil)
avPlayer.play()
paused = false
}
override func viewDidDisappear(animated: Bool) {
avPlayer.pause()
paused = true
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
// Dispose of any resources that can be recreated.
}
}
I found a simple solution for this:
on viewDidLoad ( You can set this on storyboard too. )
loginAlpha.hidden = true
signupAlpha.hidden = true
and on viewDidAppear
signupAlpha.alpha = 0
loginAlpha.alpha = 0
loginAlpha.hidden = false
signupAlpha.hidden = false
I have to draw a label or button on top of video relay next previous , leave comment . List of video have it, once user select one item from the table,it need to play, Once player play finished, those buttons or label should come on top of video
Here is my code :
comPlayerControl = AVPlayerViewController()
if let player = comPlayerControl {
let videoURL: String = "http://cdnapi.kaltura.com/p/11/sp/11/playManifest/entryId/"+selectedSubmission.transcodeRefId+"/format/applehttp/protocol/http/a.m3u8"
let playerItem = AVPlayerItem(URL: NSURL(string: videoURL)! )
commmentPlayer = AVPlayer(playerItem: playerItem)
player.player = commmentPlayer
player.view.frame = videoCell.frame
player.view.sizeToFit()
player.showsPlaybackControls = true
NSNotificationCenter.defaultCenter().addObserver(
self,
selector: #selector(CommentsTableViewController.playerDidFinishPlaying(_:)),
name: AVPlayerItemDidPlayToEndTimeNotification,
object: playerItem
)
comPlayerControl.delegate = self
videoCell.addSubview(player.view)
}
func playerDidFinishPlaying(note: NSNotification) {
print("Video Finished")
let DynamicView=UIView(frame: CGRectMake(100, 200, 100, 100))
DynamicView.backgroundColor=UIColor.greenColor()
DynamicView.layer.cornerRadius=25
DynamicView.layer.borderWidth=2
DynamicView.layer.zPosition = 1;
comPlayerControl.view.addSubview(DynamicView)
}
requirement like this
You're using an AVPlayerViewController, so there's no reason to access your application's window like in Alessandro Ornano's answer. Why reinvent the wheel? Every AVPlayerViewController has a contentOverlayView property which allows you to place views between the player and the controls.
First, create a new AVPlayerItem and listen for the AVPlayerItemDidPlayToEndTimeNotification notification on that item. Load the item into your player and begin playback.
Once the item completes, the selector your specified to listen for the AVPlayerItemDidPlayToEndTimeNotification notification will be called. In that selector, access the contentOverlayView directly and add your buttons:
In some view controller or other object:
let playerVC = AVPlayerViewController()
// ...
func setupPlayer {
let playerItem = AVPlayerItem(...)
playerVC.player?.replaceCurrentItemWithPlayerItem(playerItem)
NSNotificationCenter.defaultCenter().addObserver(self, selector: #selector(VC.itemFinished), name: AVPlayerItemDidPlayToEndTimeNotification, object: playerItem)
self.presentViewController(playerVC, animated: true) {
self.playerVC.player?.play()
}
}
func itemFinished() {
let btn = UIButton(type: .System)
btn.addTarget(self, action: #selector(VC.buttonTapped), forControlEvents: .TouchUpInside)
self.playerVC.contentOverlayView?.addSubview(btn)
}
func buttonTapped() {
print("button was tapped")
// replay/comment logic here
}
As stated in the comments (and a rejected edit), buttons may not work in the contentOverlayView. For an alternate solution, see Pyro's answer.
You could also subclass AVPlayerViewController and do everything inside an instance of your subclass, but Apple warns against that:
Do not subclass AVPlayerViewController. Overriding this class’s methods is unsupported and results in undefined behavior.
I think the best way to make the avplayer buttons is explained here: IOS 8 Video Playback using AVPlayer and AVPlayerViewController .
So , I prefeer and agree with these instructions, but if you still want to
add these buttons you can try to add them to the self.window
if let app = UIApplication.sharedApplication().delegate as? AppDelegate, let window = app.window {
let myFirstButton = UIButton()
myFirstButton.setTitle("test", forState: .Normal)
window.addSubview(myFirstButton)
...
}
I recommend looking up AVPlayerLayer as a way to show buttons and other content on top of your video.
See the Advances in AVFoundation Playback WWDC presentation.
Also, check out the AVFoundationSimplePlayer-iOS example project.
Essentially, you create a view to host your player, and you make the layer behind the view into an AVPlayerLayer.
class PlayerView: UIView {
var player: AVPlayer? {
get {
return playerLayer.player
}
set {
playerLayer.player = newValue
}
}
var playerLayer: AVPlayerLayer {
return layer as! AVPlayerLayer
}
override class var layerClass: AnyClass {
return AVPlayerLayer.self
}
}
Based on the your question and from the comment/code of Ramis i have made a sample code which you may try
As mentioned by JAL the contentOverlayView should be the best option to display the control over the video in the AVPlayerController, but as per my sample demo the contentOverlayView don't have any user interaction for the buttons or other controls, as if you check in the 3D view of the AVPlayerController it has AVTouchIgnoringView/UIView in front of the contentOverlayView which may be problem in user interaction with contentOverlayView.
So another solution is to add the overlay view in the AVPlayerViewController
func addContentOverlayView() {
OverlayView.frame = CGRectMake(0,30,AVPlayerVC.view.bounds.width, 100)
OverlayView.hidden = true
OverlayView.backgroundColor = UIColor ( red: 0.5, green: 0.5, blue: 0.5, alpha: 0.379 )
let btnNext = UIButton(frame:CGRectMake(AVPlayerVC.view.bounds.width - 60,0,60,44))
btnNext.setTitle(">>", forState:.Normal)
btnNext.addTarget(self, action:"playNext", forControlEvents:.TouchUpInside)
// btnNext.layer.borderColor = UIColor ( red: 0.0, green: 0.0, blue: 1.0, alpha: 0.670476140202703 ).CGColor
// btnNext.layer.borderWidth = 1.0
OverlayView.addSubview(btnNext)
let btnReplay = UIButton(frame:CGRectMake((AVPlayerVC.view.bounds.width/2)-40,0,80,44))
btnReplay.setTitle("Replay", forState:.Normal)
btnReplay.addTarget(self, action:"replayVideo", forControlEvents:.TouchUpInside)
OverlayView.addSubview(btnReplay)
let btnPrevious = UIButton(frame:CGRectMake(0,0,80,44))
btnPrevious.setTitle("<<", forState:.Normal)
btnPrevious.addTarget(self, action:"previousVideo", forControlEvents:.TouchUpInside)
OverlayView.addSubview(btnPrevious)
let btnComment = UIButton(frame:CGRectMake((AVPlayerVC.view.bounds.width/2)-70,40,140,44))
btnComment.setTitle("Comments", forState:.Normal)
btnComment.addTarget(self, action:"openComments", forControlEvents:.TouchUpInside)
OverlayView.addSubview(btnComment)
AVPlayerVC.view.addSubview(OverlayView);
}
func playNext() {
prevItem = AVPlayerVC.player?.currentItem
OverlayView.hidden = true
commmentQueuePlayer.advanceToNextItem()
}
func replayVideo() {
OverlayView.hidden = true
AVPlayerVC.player?.currentItem?.seekToTime(kCMTimeZero)
AVPlayerVC.player?.play()
}
func previousVideo() {
OverlayView.hidden = true
if prevItem != AVPlayerVC.player?.currentItem {
if (commmentQueuePlayer.canInsertItem(prevItem!, afterItem:AVPlayerVC.player?.currentItem)) {
//commmentQueuePlayer.insertItem(prevItem!, afterItem:AVPlayerVC.player?.currentItem)
commmentQueuePlayer.replaceCurrentItemWithPlayerItem(prevItem)
prevItem = AVPlayerVC.player?.currentItem
replayVideo()
}
} else {
replayVideo()
//Else display alert no prev video found
}
}
func stopedPlaying() {
if prevItem == nil {
prevItem = AVPlayerVC.player?.currentItem
}
OverlayView.hidden = false
}
At the initial setup we set the AVPlayerController,AVQueuePlayer etc... at that time we can add the overlay on the AVPlayerController
For the previous item there is no direct available and as per documentation the item will be remove once it's next item is played , so we have two option like replaceCurrentItemWithPlayerItem or insertItem(item: AVPlayerItem, afterItem: AVPlayerItem?)
If you need to check complete code you can check it from :
https://gist.github.com/Pyrolr/debb4fca8f608b1300e099a5b3547031
Note: This is just like prototype, it is not working perfectly in all the cases but it can help you in understanding the basic functionality you wnat and you can improve/optimise based on your requirements
Check Below code, I am able to add the button on overlay as well as button event is being called.

button.translatesAutoresizingMaskIntoConstraints = false
NSLayoutConstraint.activate([

])
return button
}()
