How to access the saved file path downloaded from URl - swift

Question

I have used this process to download file from the link. Now i want the file path to access this video and play with APPlayer:
#IBAction func btnplayClicked(sender: AnyObject) {
let videoImageUrl = "https://devimages-cdn.apple.com/samplecode/avfoundationMedia/AVFoundationQueuePlayer_HLS2/master.m3u8"
dispatch_async(dispatch_get_global_queue(DISPATCH_QUEUE_PRIORITY_DEFAULT, 0), {
let url = NSURL(string: videoImageUrl);
let urlData = NSData(contentsOfURL: url!);
if(urlData != nil)
{
let documentsPath = NSSearchPathForDirectoriesInDomains(.DocumentDirectory, .UserDomainMask, true)[0];
let filePath="\(documentsPath)/video.mp4";
dispatch_async(dispatch_get_main_queue(), {
urlData?.writeToFile(filePath, atomically: true);
PHPhotoLibrary.sharedPhotoLibrary().performChanges({
PHAssetChangeRequest.creationRequestForAssetFromVideoAtFileURL(NSURL(fileURLWithPath: filePath))
}) { completed, error in
if completed {
print("Video is saved!")
if let path = NSBundle.mainBundle().pathForResource("video", ofType: ".mp4")
{
let apath = NSURL(fileURLWithPath: path)
let video = AVPlayer(URL: apath)
let videoPlayer = AVPlayerViewController()
videoPlayer.player = video
self.presentViewController(videoPlayer, animated: true, completion: {
video.play()
})
}
}
}
})
}
})
}
Video is downloaded and i can see it on gallery.But AVPlayer does not play the video..What am i doing wrong here..?

Answer 1

AS iOS greek Greek told you are accessing wrong path,you can do it with this approach:
if completed {
dispatch_async(dispatch_get_main_queue(), {
// Call UI related operations
let apath = NSURL(fileURLWithPath: filePath)
let video = AVPlayer(URL: apath)
let videoPlayer = AVPlayerViewController()
videoPlayer.player = video
self.presentViewController(videoPlayer, animated: true, completion: {
video.play()
})
})
}

Answer 2

Did you try to load the AVPlayer directly from the cached path? doing so:
if completed {
let video = AVPlayer(URL: NSURL(fileURLWithPath: filePath))
let videoPlayer = AVPlayerViewController()
videoPlayer.player = video
self.presentViewController(videoPlayer, animated: true, completion: {
video.play()
})
}
