Saving Video to Parse & Playback

Question

So i'm using this custom class to record my video -- https://github.com/piemonte/PBJVision. I am attempting to record video in my iOS app and I can't seem to get the code correct to upload the file to my parse server. A few things:

• In the PBJVision class it allows you to use NSURL(fileWithPath:videoPath) to access the asset after the video has been recorded.

• To access the Data in the asset and save to Parse, I use the following function:

   func vision(vision: PBJVision, capturedVideo videoDict: [NSObject : AnyObject]?, error: NSError?) {
  if error != nil {
      print("Encountered error with video")
      isVideo = false
  } else {
      let currentVideo = videoDict
      let videoPath = currentVideo![PBJVisionVideoPathKey] as! String
      print("The video path is: \(videoPath)")
  
      self.player = Player()
      self.player.delegate = self
      self.player.view.frame = CGRect(x: cameraView.frame.origin.x, y: cameraView.frame.origin.y, width: cameraView.frame.width, height: cameraView.frame.height)
  
      self.player.playbackLoops = true
  
      videoUrl = NSURL(fileURLWithPath: videoPath)
      self.player.setUrl(videoUrl)
  
      self.cameraView.addSubview(self.player.view)
      self.player.playFromBeginning()
      nextButton.hidden = false
      isVideo = true
  
      let contents: NSData?
      do {
          contents = try NSData(contentsOfFile: videoPath, options: NSDataReadingOptions.DataReadingMappedAlways)
      } catch _ {
          contents = nil
      }
  
      print(contents)
  
      let videoObject = PFObject(className: "EventChatroomMessages")
      videoObject.setValue(user, forKey: "user")
      videoObject.setValue("uG7v2KWBQm", forKey: "eventId")
      videoObject.setValue(NSDate(), forKey: "timestamp")
  
      let videoFile: PFFile?
      do {
          videoFile = try PFFile(name: randomAlphaNumericString(26) + ".mp4", data: contents!, contentType: "video/mp4")
          print("VideoFile: \(videoFile)")
      } catch _ {
          print("error")
      }
  
      print(videoFile)
  
      videoObject.setValue(videoFile, forKey: "image")
      videoObject.saveInBackgroundWithBlock {
          (success: Bool, error: NSError?) -> Void in
          if success == true {
              ProgressHUD.showSuccess("Video Saved.", interaction: false)
              dispatch_async(dispatch_get_main_queue()) {
                  ProgressHUD.dismiss()
              }
          } else {
              ProgressHUD.showError("Error Saving Video.", interaction: false)
              dispatch_async(dispatch_get_main_queue()) {
                  ProgressHUD.dismiss()
              }
          }
      }
  }
  

  }

I am then using a UITableView to display my data from Parse. Here is how I retrieve my asset back from Parse and into my AVPlayer(): // Create Player for Reaction let player = Player() player.delegate = self player.view.frame = CGRectMake(0.0, nameLabel.frame.origin.y + nameLabel.frame.size.height + 0.0, self.view.frame.width, 150) player.view.backgroundColor = UIColor.whiteColor()

    let video = message.objectForKey("image") as! PFFile
    let urlFromParse = video.url!
    print(urlFromParse)

    let url = NSURL(fileURLWithPath: video.url!)
    print(url)

    let playerNew = AVPlayer(URL: url!)
    let playerLayer = AVPlayerLayer(player: playerNew)
    playerLayer.frame = CGRectMake(0.0, nameLabel.frame.origin.y + nameLabel.frame.size.height + 0.0, self.view.frame.width, 150)
    cell.layer.addSublayer(playerLayer)
    playerLayer.backgroundColor = UIColor.whiteColor().CGColor
    playerNew.play()

I copy the value that is returned from urlFromParse which is (http://parlayapp.herokuapp.com/parse/files/smTrXDGZhlYQGh4BZcVvmZ2rYB9kA5EhPkGbj2R2/58c0648ae4ca9900f2d835feb77f165e_file.mp4) and paste it into my browser and the video plays in browser. Am I correct to assume the file has been saved correctly?

When I go to run my app, the video does not play.Any suggestion on what i'm doing wrong?

I have found that playing video using the pfFile.url does not work. You have to write the NSData from the PFFIle to a local file using the right extension (mov) and then play the video using the local file as the source.
