Saving Video to Parse & Playback - swift

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.
