Select video from PhotoLibrary in iOS using Swift

Based on Swift 2.2

Suppose you have a imagePickerController and when you want to select both images and videos:

let imagePickerController = UIImagePickerController()var videoURL: NSURL?    @IBAction func selectImageFromPhotoLibrary(sender: UIBarButtonItem) {  imagePickerController.sourceType = .PhotoLibrary  imagePickerController.delegate = self  imagePickerController.mediaTypes = ["public.image", "public.movie"]  presentViewController(imagePickerController, animated: true, completion: nil)    }

Then after the video is selected, print out its NSURL.

func imagePickerController(picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [String : AnyObject]) {  videoURL = info["UIImagePickerControllerReferenceURL"] as? NSURL  print(videoURL)  imagePickerController.dismissViewControllerAnimated(true, completion: nil)}

For question 2:

Yes, you can do it through AVPlayer, you need import AVKit and AVFoundation, and you code may look like this:

if let videoURL = videoURL{  let player = AVPlayer(URL: videoURL)  let playerViewController = AVPlayerViewController()  playerViewController.player = player  presentViewController(playerViewController, animated: true) {    playerViewController.player!.play()  }}

I made a demo here you can refer, maybe not 100% what you want.

@IBOutlet weak var imgView: UIImageView!var imagePickerController = UIImagePickerController()var videoURL : NSURL?@IBAction func btnSelectVideo_Action(_ sender: Any) {    imagePickerController.sourceType = .savedPhotosAlbum    imagePickerController.delegate = self    imagePickerController.mediaTypes = [kUTTypeMovie as String]    present(imagePickerController, animated: true, completion: nil)}func imagePickerController(_ picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [String : Any]) {    videoURL = info[UIImagePickerControllerMediaURL]as? NSURL    print(videoURL!)    do {        let asset = AVURLAsset(url: videoURL as! URL , options: nil)        let imgGenerator = AVAssetImageGenerator(asset: asset)        imgGenerator.appliesPreferredTrackTransform = true        let cgImage = try imgGenerator.copyCGImage(at: CMTimeMake(0, 1), actualTime: nil)        let thumbnail = UIImage(cgImage: cgImage)        imgView.image = thumbnail    } catch let error {        print("*** Error generating thumbnail: \(error.localizedDescription)")    }    self.dismiss(animated: true, completion: nil)}

For question 2:

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

Swift 5+ solution:

func openVideoGallery() {    picker = UIImagePickerController()    picker.delegate = self    picker.sourceType = .savedPhotosAlbum    picker.mediaTypes = ["public.movie"]          picker.allowsEditing = false    present(picker, animated: true, completion: nil)}
