hello im trying to play video in background but its give an error and the error is " unexpectedly found nil while unwrapping an Optional value " and im already set the video in Bundle and select copy if need
this the my code
import UIKit
import AVFoundation
class ViewController: UIViewController {
var avPlayer: AVPlayer!
var avPlayerLayer: AVPlayerLayer!
var paused: Bool = false
override func viewDidLoad() {
super.viewDidLoad()
let url = Bundle.main.url(forResource: "Grad_Cap_Toss", withExtension: "mp4")
avPlayer = AVPlayer(url: url!)
avPlayerLayer = AVPlayerLayer(player: avPlayer)
avPlayerLayer.videoGravity = AVLayerVideoGravityResizeAspectFill
avPlayer.volume = 0
avPlayer.actionAtItemEnd = AVPlayerActionAtItemEnd.none
avPlayerLayer.frame = view.layer.bounds
view.backgroundColor = UIColor.clear;
view.layer.insertSublayer(avPlayerLayer, at: 0)
NotificationCenter.default.addObserver(self,selector: Selector(("playerItemDidReachEnd:")),name: NSNotification.Name.AVPlayerItemDidPlayToEndTime,object: avPlayer.currentItem)
}
please any body have ideas for that , thank you
First, drag and drop video file in your project.
Then import AVFundation.
Add example: var player: AVPlayer?
#IBOutlet weak var videoView: UIView! - Connect view from storyboard to your VC class.
After that, you paste this code into your ViewController.
call "playBackgoundVideo()" in your viewDidLoad()
private func playBackgoundVideo() {
if let filePath = Bundle.main.path(forResource: "your_video_here", ofType:"mp4") {
let filePathUrl = NSURL.fileURL(withPath: filePath)
player = AVPlayer(url: filePathUrl)
let playerLayer = AVPlayerLayer(player: player)
playerLayer.frame = self.videoView.bounds
playerLayer.videoGravity = AVLayerVideoGravityResizeAspectFill
NotificationCenter.default.addObserver(forName: .AVPlayerItemDidPlayToEndTime, object: self.player?.currentItem, queue: nil) { (_) in
self.player?.seek(to: kCMTimeZero)
self.player?.play()
}
self.videoView.layer.addSublayer(playerLayer)
player?.play()
}
}
This is swift 4.0
it works ^__^
I had a similar problem and followed the instructions from Rick's answer to resolve it.
My problem was that I didn't have the video file in the bundle resources.
Check if your video file is listed in Copy Bundle Resources under Build Phases in the project. If not , use the + button to add the file in there.
Also you might be missing the avPlayer.play() statement in your code.
I was also trying to play a video in the background of my login page's view controller. I think the main issue is that the syntax you're using is deprecated.
Your code might look like the following:
import UIKit
import AVKit
import AVFoundation
class ViewController: UIViewController {
#IBOutlet var blackOverlay: UIView!
// init video background and its path
var player: AVPlayer?
let videoURL: NSURL = Bundle.main.url(forResource: "videoName", withExtension: "mp4")! as NSURL
override func viewDidLoad() {
super.viewDidLoad()
// Adds a black overlay to the looped video in question
blackOverlay.alpha = 0.75;
blackOverlay.layer.zPosition = 0;
// begin implementing the avplayer
player = AVPlayer(url: videoURL as URL)
player?.actionAtItemEnd = .none
player?.isMuted = true
let playerLayer = AVPlayerLayer(player: player)
playerLayer.videoGravity = AVLayerVideoGravityResizeAspectFill
playerLayer.zPosition = -1
playerLayer.frame = view.frame
view.layer.addSublayer(playerLayer)
player?.play()
// add observer to watch for video end in order to loop video
NotificationCenter.default.addObserver(self, selector: #selector(ViewController.loopVideo), name: NSNotification.Name.AVPlayerItemDidPlayToEndTime, object: self.player)
// if video ends, will restart
func playerItemDidReachEnd() {
player!.seek(to: kCMTimeZero)
}
}
// maybe add this loop at the end, after viewDidLoad
// func loopVideo() { player?.seek(to: kCMTimeZero) player?.play()}}
Please let me know if this helps!
Drag and drop video file in your project.
Then import AVFundation
List item
#IBOutlet weak var videoView: UIView!, #IBOutlet weak var label: UILabel!,#IBOutlet weak var image: UIImageView!,#IBOutlet weak var loginBtn: UIButton!
Connect view from storyboard to your VC class.
And then paste the given code in your ViewController and call playVideo() function in viewDidLoad().
func playVideo(){
guard let path = Bundle.main.path(forResource: "intro", ofType: "mp4") else {
return
}
let player = AVPlayer(url: URL(fileURLWithPath: path))
let playerLayer = AVPlayerLayer(player: player)
playerLayer.frame = self.view.bounds
playerLayer.videoGravity = .resizeAspectFill
self.videoLayer.layer.addSublayer(playerLayer)
player.play()
videoLayer.bringSubviewToFront(image)
videoLayer.bringSubviewToFront(label)
videoLayer.bringSubviewToFront(loginBtn)
videoLayer.bringSubviewToFront(signupBtn)
}
If url is nil and the video is being successfully copied into the bundle, the likely problem is case sensitivity. Make sure the filename is using the correct case. The iOS device filesystem is case sensitive, where as the iPhone simulator is not.
I had a same problem when I tried to play video background. I think it is the problem of video resource.
I resolved the problem like this way.
When you drag your video, you should check both of 'Copy items if needed' and 'Add to targets'.
Or you can just right click on the project navigator, click 'Add' to add resource.

I added a video to my viewController() as a background and I want to loop it or in other words make it repeat itself forever.
Here is all the code:
import UIKit
import AVKit
import AVFoundation
class ViewController: UIViewController {
override func viewDidLoad() {
super.viewDidLoad()
// Do any additional setup after loading the view.
}
override func viewDidAppear(_ animated: Bool) {
super.viewDidAppear(true)
let player = AVPlayer(url: URL(fileURLWithPath: Bundle.main.path(forResource: "background", ofType: "mp4")!))
let layer = AVPlayerLayer(player: player)
layer.frame = view.bounds
layer.videoGravity = .resizeAspectFill
layer.repeatCount = .greatestFiniteMagnitude
layer.repeatDuration = .greatestFiniteMagnitude
view.layer.addSublayer(layer)
player.play()
}
}
When I run the app It only plays once and never repeats itself.
Any suggestions? Thanks.
One solution is to observe AVPlayerItemDidPlayToEndTime and then simply restart the video.
NotificationCenter.default.addObserver(
forName: .AVPlayerItemDidPlayToEndTime,
object: player.currentItem,
queue: .main
) { [weak player] _ in
player?.seek(to: .zero)
player?.play()
}
Don't forget to detach this observer whenever it's no longer necessary.
Use an AVPlayerLooper. Its name tells you that this is exactly what it's for.
https://developer.apple.com/documentation/avfoundation/avplayerlooper
A couple comments.
According to AVPlayerLayer doc: Set one or the other. Not both.
If both repeatDuration and repeatCount are specified the behavior is
undefined.
In general, I've struggled with getting AVPlayerLayer to repeat mp4's using the repeatCount or repeatDuration way. Instead I use AVQueuePlayer with a AVPlayerLooper. Credit to: https://developer.apple.com/forums/thread/658909
import AVFoundation
var playerQueue: AVQueuePlayer!
var playerLayer: AVPlayerLayer!
var playerLooper: AVPlayerLooper!
private func configLooper(file: String, ext: String) {
guard let videoURL = Bundle.main.url(forResource: file, withExtension: ext) else { return }
playerQueue = AVQueuePlayer()
playerLayer = AVPlayerLayer(player: playerQueue)
let playerItem = AVPlayerItem(url: videoURL)
playerLooper = AVPlayerLooper(player: playerQueue, templateItem: playerItem)
playerLayer.frame = view.bounds
playerLayer.videoGravity = AVLayerVideoGravity.resizeAspectFill
view.layer.insertSublayer(playerLayer, below: someOtherView.layer)
playerQueue.play()
}
Once users go to this specific page, I want the video to immediately start playing inside of a UIView with no controls. It will just loop like a gif. This is code I found off of github and it doesn't seem to work. It just shows the white UIView when I pull up the page. My file name is correct as well.
import Foundation
import UIKit
import AVKit
import AVFoundation
class RampWallPush: UIViewController {
#IBOutlet weak var videoView: UIView!
var player: AVPlayer?
override func viewDidLoad() {
super.viewDidLoad()
// Load video resource
if let videoUrl = Bundle.main.url(forResource: "small", withExtension: "mp4") {
// Init video
self.player = AVPlayer(url: videoUrl)
self.player?.isMuted = true
self.player?.actionAtItemEnd = .none
// Add player layer
let playerLayer = AVPlayerLayer(player: player)
playerLayer.videoGravity = AVLayerVideoGravity.resizeAspectFill
playerLayer.frame = view.frame
// Add video layer
self.videoView.layer.addSublayer(playerLayer)
// Play video
self.player?.play()
// Observe end
NotificationCenter.default.addObserver(self, selector: #selector(playerItemDidReachEnd), name: NSNotification.Name.AVPlayerItemDidPlayToEndTime, object: self.player?.currentItem)
}
}
// MARK: - Loop video when ended.
#objc func playerItemDidReachEnd(notification: NSNotification) {
self.player?.seek(to: CMTime.zero)
self.player?.play()
}
}
Your code is works you need to verify the file exists in your project and .......
// Load video resource
if let videoUrl = Bundle.main.url(forResource: "sample", withExtension: "mp4") {
// exists
}
else {
print("NoFile")
}
So select the file and
You need to change the frame
playerLayer.frame = CGRect(x:0,y:0,width:200,height:300)
self.videoView.layer.addSublayer(playerLayer)
playerLayer.center = videoView.center
Created a demo Here
hello i am new to swift and i am using AVPlayerViewController for plaing video from my url but issue is that i am not able to load video only black screen showing let me show my code
Code
import UIKit
import AVKit
import AVFoundation
class ViewController: UIViewController {
#IBOutlet weak var viewPlayer: UIView!
var player: AVPlayer!
var avpController = AVPlayerViewController()
var url = "https://www.youtube.com/watch?v=HsQvAnCGxzY"
override func viewDidLoad() {
super.viewDidLoad()
let url = URL(string: self.url)
player = AVPlayer(url: url!)
avpController.player = player
avpController.view.frame.size.height = viewPlayer.frame.size.height
avpController.view.frame.size.width = viewPlayer.frame.size.width
self.viewPlayer.addSubview(avpController.view)
// Do any additional setup after loading the view, typically from a nib.
}
}
Please refer code given and tell me where i am done wrong so that i can able to play video Thanks In Advance
Actually Its problem of URL .
AVPlayer never supports YouTube video. It supports mp4 format.
If you want to play a video in your ViewController, you have to use AVPlayerLayer. You have to implement player controllers yourself.
override func viewDidLoad() {
super.viewDidLoad()
// creating video url
guard let videoURL = URL(string: "https://clips.vorwaerts-gmbh.de/big_buck_bunny.mp4") else {
return
}
// create AVPlayer
let player = AVPlayer(url: videoURL)
// setup AVPlayerLayer
let playerLayer = AVPlayerLayer(player: player)
playerLayer.frame = self.view.bounds
self.view.layer.addSublayer(playerLayer)
// start playing
player.play()
}
Otherwise use AVPlayerViewController. Instead of using its view present the viewController itself.
override func viewDidLoad() {
super.viewDidLoad()
// creating video url
guard let videoURL = URL(string: "https://www.learningcontainer.com/wp-content/uploads/2020/05/sample-mp4-file.mp4") else {
return
}
// setup AVPlayer and AVPlayerViewController
let player = AVPlayer(url: videoURL)
let playerViewController = AVPlayerViewController()
playerViewController.player = player
}
override func viewDidAppear(_ animated: Bool) {
// presenting playerViewController only after the viewControllers view was added to a view hierarchy.
self.present(playerViewController, animated: true) {
playerViewController.player!.play()
}
}
I'm trying to create an app that will change videos on each button press.
Currently: The video loops and the button does nothing
Goals: The button will cycle to the next video based on the array index. I plan on associating another array with text descriptions to go along with each video.
Thoughts: I think a JSON based implementation would probably work better. This is my first iOS app and I'm trying to keep it simple. Thoughts and help are greatly appreciated!
Here is the function that loops the video. The name of name of the video is held in an array called videoId:
class WorkoutViewController: UIViewController{
#IBOutlet weak var videoView: UIView!
#IBOutlet weak var infoCardView: UIView!
var currentVidIndex: Int = 0
var player: AVPlayer?
var playerLayer: AVPlayerLayer?
override func viewDidLoad() {
super.viewDidLoad()
shadowBackground()
}
var videoId: [String] = ["bodyweight_fitness_arch","bodyweight_fitness_assisted_squat","bodyweight_fitness_band_dislocates"]
func setLoopingVideo(){
let path = Bundle.main.path(forResource: videoId[currentVidIndex], ofType: "mp4")
let url = URL.init(fileURLWithPath: path!)
let player = AVPlayer(url: url)
let playerLayer = AVPlayerLayer(player: player)
playerLayer.frame = videoView.bounds
self.videoView.layer.insertSublayer(playerLayer, at: 0)
player.play()
// Create observer to monitor when video ends, when it does so set the video time to the start (zero)
NotificationCenter.default.addObserver(forName: NSNotification.Name.AVPlayerItemDidPlayToEndTime,object: player.currentItem, queue: nil)
{
Notification in player.seek(to: kCMTimeZero)
player.play()
}
func shadowBackground(){
infoCardView.layer.cornerRadius = 3.0
infoCardView.layer.shadowColor =
UIColor.black.withAlphaComponent(0.6).cgColor
infoCardView.layer.shadowOffset = CGSize(width: 0, height: 0)
infoCardView.layer.shadowOpacity = 0.9
videoView.layer.cornerRadius = 3.0
videoView.layer.shadowColor =
UIColor.black.withAlphaComponent(0.6).cgColor
videoView.layer.shadowOffset = CGSize(width: 0, height: 0)
videoView.layer.shadowOpacity = 0.9
}
override func viewDidAppear(_ animated: Bool) {
setLoopingVideo()
}
#IBAction func showNextVideo(_ sender: UIButton) {
if currentVidIndex < videoId.count{
currentVidIndex += 1
print (currentVidIndex)
} else {
NSLog("Nothing")
}
}
What it looks like
If you want to change a video on every button click, you have to create always new AVPlayer object.
create and remember your AVPlayer object
create and remember your AVPlayerLayer
-- when button clicked --
remove AVPlayerLayer from the parent
stop AVPlayer (old video)
goto step 1 with new video URL
Here was my solution:
func clearVid(){
if let player = self.player{
player.pause()
self.player = nil
}
if let layer = self.playerLayer{
layer.removeFromSuperlayer()
self.playerLayer = nil
}
self.videoView.layer.sublayers?.removeAll()
}
I have followed a tutorial and trying to get a video to pop up when I press a button. The video pops up but the actual video does not start playing and I just get this screen....
Blank Screen image
the code is as follows:
import UIKit
import AVFoundation
import AVKit
class ViewController: UIViewController {
var playerController = AVPlayerViewController()
var player:AVPlayer?
override func viewDidLoad() {
super.viewDidLoad()
let videoString:String? = Bundle.main.path(forResource: "motorbikes", ofType: ".m4v")
if let url = videoString {
let videoURL = NSURL(fileURLWithPath: url)
self.player = AVPlayer(url: videoURL as URL)
}
}
#IBAction func goButton(_ sender: Any) {
self.present(self.playerController, animated: true, completion: {
self.playerController.player?.play()
})
}
}
You have forgot to set playercontroller's player instance as phuc-nguyen said
or else you can make use of AVPlayerLayer to play the video without using AVPlayerViewController
let player = AVPlayer(url: URL(string: "path/myvideo.mp4")!)
let playerLayer = AVPlayerLayer(player: player)
playerLayer.frame = self.view.bounds
self.view.layer.addSublayer(playerLayer)
player.play()
Using AVPlayerLayer you can customize the player like adding your own controls or views and it won't be a full screen view usually though.
But if you are not looking for any customization its good to stick with AVPlayerViewController it has all the controls baked in
Depends on your requirement
