Impossible to stream video after downloading from Parse

Question

It seems that I can't stream my videos once I downloaded them from Parse backend. However I know that the videos are working well as you can play it from Chrome but not from Safari ( I don't know why ...).

My code to play the video on the AVPlayer is also right since I test it for multiple NSUrl from local database.

Several posts about it confirm that there is a problem going on but no one has an answer.

The secret is to get the PFFIle data, save it locally with the proper extention (mov) and treaming the local file. look at this entry [Cant stream video (PFFile) from parse server][1], the second anwser.

The PFFIle was created with the following code:

let videoPath = info[UIImagePickerControllerMediaURL] as! NSURL


      let imageData = NSData (contentsOfURL:videoPath)! as NSData

            do  {

              let file = try PFFile(name: "_mov", data: imageData, contentType: "video/quicktime")
              videoSaveSelected(file )
            } catch let error as NSError {
              print("Error generating PFFile: \(error)")
            }

This is the code for the player

import UIKit
import AVKit
import MobileCoreServices
import AssetsLibrary
import AVFoundation
import Parse
import ParseUI

class VideoPlayerViewController: UIViewController {

  var videoUrl: NSURL!
  var file: PFFile!

    override func viewDidLoad() {
        super.viewDidLoad()


      // navigation
      let backButtonCustom = UIButton( frame: CGRectMake(0, 0, 22, 22))
      let backIcon = UIImage(named: "0836-arrow-left")?.imageWithRenderingMode(UIImageRenderingMode.AlwaysTemplate)
      backButtonCustom.setImage(backIcon, forState: UIControlState.Normal)
      backButtonCustom.addTarget(self, action: #selector(ReqDataEntryLgViewController.doneButtonTapped), forControlEvents: UIControlEvents.TouchUpInside)
      navigationItem.leftBarButtonItem = UIBarButtonItem(customView: backButtonCustom)

      let doneButton = UIBarButtonItem(title: "Done", style: .Done, target: self, action: #selector(ReqDataEntryLgViewController.doneButtonTapped))
      self.navigationItem.setRightBarButtonItems([doneButton], animated: true)




      // video player

      let playerController = AVPlayerViewController()

      self.addChildViewController(playerController)
      self.view.addSubview(playerController.view)
      playerController.view.frame = self.view.frame

      // get data from PFFile in database
      file!.getDataInBackgroundWithBlock({
        (movieData: NSData?, error: NSError?) -> Void in
        if (error == nil) {

                    let documentsPath : AnyObject = NSSearchPathForDirectoriesInDomains(.DocumentDirectory,.UserDomainMask,true)[0]
          let destinationPath:NSString = documentsPath.stringByAppendingString("/file.mov")

          let filemanager = NSFileManager.defaultManager()
          do {
             try filemanager.removeItemAtPath(destinationPath as String)
          } catch  {
            print("Ooops! Something went wrong: \(error)")
          }

          // write to local file
          movieData!.writeToFile ( destinationPath as String, atomically:true)

//          do {
//            let attr : NSDictionary? = try NSFileManager.defaultManager().attributesOfItemAtPath(destinationPath as String)
//            
//            if let _attr = attr {
//              let fileSize = _attr.fileSize()
//              print ("Movie Size \(fileSize)" )
//            }
//          } catch {
//            print("Ooops! Something went wrong getting size: \(error)")
//          }

          let playerItem = AVPlayerItem(asset: AVAsset(URL: NSURL(fileURLWithPath: destinationPath as String)))
          let player = AVPlayer(playerItem: playerItem)
          playerController.player = player
          player.play()
        } else {
          print ("error on getting movie data \(error?.localizedDescription)")
        }
      })




  }


  func doneButtonTapped(){

    navigationController?.popViewControllerAnimated(true)
  }

    override func didReceiveMemoryWarning() {
        super.didReceiveMemoryWarning()
        // Dispose of any resources that can be recreated.
    }
