iOS Video Backgrounds

First things first, import the MediaPlayer framework:

@import MediaPlayer;

Next, we create a new MPMoviePlayerController instance within our viewDidLoad: method.

NSURL *videoURL = [[NSBundle mainBundle]   URLForResource:@"video" withExtension:@"mov"];
    
self.moviePlayer = [[MPMoviePlayerController alloc] initWithContentURL:videoURL];

self.moviePlayer.controlStyle = MPMovieControlStyleNone;
self.moviePlayer.scalingMode = MPMovieScalingModeAspectFill;

self.moviePlayer.view.frame = self.view.frame;[self.view insertSubview:self.moviePlayer.view atIndex:0];

[self.moviePlayer play];

While we’re in viewDidLoad:, let’s go ahead and add a notification handler to help us loop the video.

[[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(loopVideo) name:MPMoviePlayerPlaybackDidFinishNotification object:self.moviePlayer];

Time to set up that loopVideo function we’re calling in the above block.

- (void)loopVideo {
    [self.moviePlayer play];
}

And we’re done! Now all that’s left to do is throw a few UI elements on top.

Note: MPMoviePlayerController is deprecated in iOS 9.

So for ios9 and above use AVPlayer

	var player: AVPlayer?
	override func viewDidLoad() {
	super.viewDidLoad()
	// Load the video from the app bundle.
	let videoURL: NSURL = NSBundle.mainBundle().URLForResource("video", withExtension: "mov")!
	player = AVPlayer(URL: videoURL)
	player?.actionAtItemEnd = .None
	player?.muted = true
	let playerLayer = AVPlayerLayer(player: player)
	playerLayer.videoGravity = AVLayerVideoGravityResizeAspectFill
	playerLayer.zPosition = -1
	playerLayer.frame = view.frame
	view.layer.addSublayer(playerLayer)
	player?.play()
	//loop video
	NSNotificationCenter.defaultCenter().addObserver(self,
	selector: "loopVideo",
	name: AVPlayerItemDidPlayToEndTimeNotification,
	object: nil)
	}
	func loopVideo() {
	player?.seekToTime(kCMTimeZero)
	player?.play()
	}
