SJVideoPlayer Not Playing video Display black screen

I'm simply use following code but it display black screen.

SJVideoPlayer *videoPlayer = [SJVideoPlayer player];
videoPlayer.view.frame = CGRectMake(0, 20, 200, 200 * 9/16.0);
[self.view addSubview:videoPlayer.view];
videoPlayer.URLAsset = [[SJVideoPlayerURLAsset alloc] initWithURL:[NSURL URLWithString:@"http://yxfile.idealsee.com/9f6f64aca98f90b91d260555d3b41b97_mp4.mp4"]];
[videoPlayer play];

In log display following output:-

SJBaseVideoPlayer<0x111dc82d0>.SJVideoPlayerPlayStatus.Prepare

It was released, you should have a strong reference to it.

@interface YourViewController : UIViewController
// strong reference
@property (nonatomic, strong) SJVideoPlayer *videoPlayer;
@end

@implementation YourViewController

- (void)viewDidLoad {
    [super viewDidLoad];
    _videoPlayer = [SJVideoPlayer player];
    _videoPlayer.view.frame = CGRectMake(0, 20, 200, 200 * 9/16.0);
    [self.view addSubview:_videoPlayer.view];
    _videoPlayer.URLAsset = [[SJVideoPlayerURLAsset alloc] initWithURL:[NSURL URLWithString:@"http://yxfile.idealsee.com/9f6f64aca98f90b91d260555d3b41b97_mp4.mp4"]];
