How do i make a looping video in swift - ios

Question

How would i go about making a local .mp4 file with no sound play on a loop, so it would only take up part of the screen and have no user controls. Just a looping video, sort of like a gif. I am using xcode, swift2.
class ViewController: UIViewController {
var playerViewController = AVPlayerViewController()
var playerView = AVPlayer()
override func viewDidLoad() {
super.viewDidLoad()
// Do any additional setup after loading the view, typically from a nib.
}
override func viewDidAppear(animated: Bool) {
var fileURL = NSURL(fileURLWithPath: "/Users/Mantas/Desktop/123/123/video-1453562323.mp4.mp4")
playerView = AVPlayer(URL: fileURL)
playerViewController.player = playerView
self.presentViewController(playerViewController, animated: true){
self.playerViewController.player?.play()
}
}
}
I have made this, it plays the video, but in full screen, i dont know how to make it only take up part of the screen and how to make it loop

Alternate version in Swift 3.0:
Add these properties:
fileprivate var player: AVPlayer? {
didSet { player?.play() }
}
fileprivate var playerObserver: Any?
Add this to your deinit:
deinit {
guard let observer = playerObserver else { return }
NotificationCenter.default.removeObserver(observer)
}
Add this function:
func videoPlayerLayer() -> AVPlayerLayer {
let fileURL = URL(fileURLWithPath: mediaPath)
let player = AVPlayer(url: fileURL)
let resetPlayer = {
player.seek(to: kCMTimeZero)
player.play()
}
playerObserver = NotificationCenter.default.addObserver(forName: NSNotification.Name.AVPlayerItemDidPlayToEndTime, object: player.currentItem, queue: nil) { notification in
resetPlayer()
}
self.player = player
return AVPlayerLayer(player: player)
}
Then add to your layer wherever you feel like (viewDidLoad, viewDidAppear, viewDidFinishLayingOutSubviews):
let playerLayer = videoPlayerLayer()
playerLayer.frame = view.bounds
view.layer.insertSublayer(playerLayer, at: 0)

Adding observer when video going to finish you can make replay the video
override func viewDidAppear(animated: Bool) {
super.viewDidAppear()
var fileURL = NSURL(fileURLWithPath: "/Users/Mantas/Desktop/123/123/video-1453562323.mp4.mp4")
playerView = AVPlayer(URL: fileURL)
NSNotificationCenter.defaultCenter().addObserver(self,
selector: "playerItemDidReachEnd:",
name: AVPlayerItemDidPlayToEndTimeNotification,
object: self.playerView.currentItem) // Add observer
playerViewController.player = playerView
//amend the frame of the view
self.playerViewController.player.frame = CGRectMake(0, 0, 200, 200)
//reset the layer's frame, and re-add it to the view
var playerLayer: AVPlayerLayer = AVPlayerLayer.playerLayerWithPlayer(self.playerView)
playerLayer.frame = videoHolderView.bounds
videoHolderView.layer.addSublayer(playerLayer)
/* Full Screen
self.presentViewController(playerViewController, animated: true){
self.playerViewController.player?.play()
} */
}
func playerItemDidReachEnd(notification: NSNotification) {
self.playerView.seekToTime(kCMTimeZero)
self.playerView.play()
}

For a seemless repeating video without a black flash. Use the AVPlayerLooper like so:
private var player: AVQueuePlayer!
private var playerLayer: AVPlayerLayer!
private var playerItem: AVPlayerItem!
private var playerLooper: AVPlayerLooper!
override func viewDidLoad(){
super.viewDidLoad()
let path = Bundle.main.path(forResource: "background_cloudy", ofType: "mov")
let pathURL = URL(fileURLWithPath: path!)
let duration = Int64( ( (Float64(CMTimeGetSeconds(AVAsset(url: pathURL).duration)) * 10.0) - 1) / 10.0 )
player = AVQueuePlayer()
playerLayer = AVPlayerLayer(player: player)
playerItem = AVPlayerItem(url: pathURL)
playerLooper = AVPlayerLooper(player: player, templateItem: playerItem,
timeRange: CMTimeRange(start: kCMTimeZero, end: CMTimeMake(duration, 1)) )
playerLayer.videoGravity = AVLayerVideoGravity.resizeAspectFill
playerLayer.frame = view.layer.bounds
view.layer.insertSublayer(playerLayer, at: 1)
}

This is tested with Swift 5, I found in https://gist.github.com/lanserxt/33fd8c479185cba181497315299e0e31
import UIKit
import AVFoundation
class LoopedVideoPlayerView: UIView {
fileprivate var videoURL: URL?
fileprivate var queuePlayer: AVQueuePlayer?
fileprivate var playerLayer: AVPlayerLayer?
fileprivate var playbackLooper: AVPlayerLooper?
func prepareVideo(_ videoURL: URL) {
let playerItem = AVPlayerItem(url: videoURL)
self.queuePlayer = AVQueuePlayer(playerItem: playerItem)
self.playerLayer = AVPlayerLayer(player: self.queuePlayer)
guard let playerLayer = self.playerLayer else {return}
guard let queuePlayer = self.queuePlayer else {return}
self.playbackLooper = AVPlayerLooper.init(player: queuePlayer, templateItem: playerItem)
playerLayer.videoGravity = .resizeAspectFill
playerLayer.frame = self.frame
self.layer.addSublayer(playerLayer)
}
func play() {
self.queuePlayer?.play()
}
func pause() {
self.queuePlayer?.pause()
}
func stop() {
self.queuePlayer?.pause()
self.queuePlayer?.seek(to: CMTime.init(seconds: 0, preferredTimescale: 1))
}
func unload() {
self.playerLayer?.removeFromSuperlayer()
self.playerLayer = nil
self.queuePlayer = nil
self.playbackLooper = nil
}
override init(frame: CGRect) {
super.init(frame: frame)
}
required init?(coder aDecoder: NSCoder) {
super.init(coder: aDecoder)
}
override func layoutSubviews() {
self.playerLayer?.frame = self.bounds
}
}
