NSURL *streamURL = [NSURL URLWithString:_videoUrl];
player = [AVPlayer playerWithURL:streamURL];
AVPlayerLayer *playerLayer = [AVPlayerLayer playerLayerWithPlayer:player];
playerLayer.frame =self.previewView.frame;
playerLayer.videoGravity = AVLayerVideoGravityResizeAspectFill;
//CGRectMake(0, 50, self.view.frame.size.width, self.view.frame.size.height/1.2);
[self.previewView.layer addSublayer:playerLayer];
// [self.playerContainer setUserInteractionEnabled:NO]; //to avoid touch events when activity is on
[self.player addObserver:self forKeyPath:#"status" options:NSKeyValueObservingOptionInitial | NSKeyValueObservingOptionNew context:NULL];
player.actionAtItemEnd = AVPlayerActionAtItemEndNone;
[[NSNotificationCenter defaultCenter] addObserver:self
selector:#selector(playerItemDidReachEnd:)
name:AVPlayerItemDidPlayToEndTimeNotification
object:[player currentItem]];

Answer 1

I have tried with your url of Video and working with below code:
header file like this:
#import <UIKit/UIKit.h>
#interface ViewController : UIViewController
#property (weak, nonatomic) IBOutlet UIView *playerView;
#end
Implementation file like this:
#import "ViewController.h"
#import <AVFoundation/AVFoundation.h>
#interface ViewController ()
#property (nonatomic) AVPlayer *player;
#end
#implementation ViewController
- (void)viewDidLoad {
[super viewDidLoad];
NSURL *url = [NSURL URLWithString:#"https://justgolive.net/assets/uploads/newrecordings/20919/19777983355a28e15326df6.mp4"];
AVPlayerItem *playerItem = [AVPlayerItem playerItemWithURL:url];
self.player = [AVPlayer playerWithPlayerItem:playerItem];
CALayer *superlayer = self.playerView.layer;
self.player.volume = 20.0;
AVPlayerLayer *playerLayer = [AVPlayerLayer playerLayerWithPlayer:self.player];
[playerLayer setFrame:self.playerView.bounds];
playerLayer.videoGravity = AVLayerVideoGravityResizeAspect;
playerLayer.frame = self.playerView.layer.bounds;
[superlayer addSublayer:playerLayer];
[self.player seekToTime:kCMTimeZero];
[self.player play];
}
