Avplayer无法在iOS 8.0中播放视频

Question

I have implemented avplayer programatically.

@interface showAskUsVideo ()
{
    AVURLAsset *asset;
    AVPlayerItem *item;
}   
@property (strong, nonatomic) AVPlayer *player;

-(void)viewWillAppear:(BOOL)animated
{
    [self playVideo];
}

-(void)playVideo {
         [playerViewController.view setFrame:CGRectMake(37, 80 ,495,220)];
         asset = [AVURLAsset assetWithURL: url];
         item = [AVPlayerItem playerItemWithAsset: asset];
         _player = [[AVPlayer alloc] initWithPlayerItem: item];
         playerViewController.showsPlaybackControls = NO;
        playerViewController.player = _player;

        [item addObserver:self forKeyPath:@"playbackLikelyToKeepUp" options:NSKeyValueObservingOptionInitial | NSKeyValueObservingOptionNew context:nil];

       [_player addObserver:self forKeyPath:@"rate" options:0 context:nil];

       [self.view addSubview:playerViewController.view];
}

But when I select deployment target 10.0 then its working fine. But for iOS 8.0 to 9.3 only PlaybackControls is seen on screen not video.

What need to change in my code?

Answer 1

Is playerViewController part of the view controller hierarchy? If not, that could explain it. Try adding it as a child view controller of your view controller:

[self addChildViewController:playerViewController];
[self.view addSubview:playerViewController.view];

Answer 2

Try like that: Add to .m

@property (nonatomic, retain)AVPlayer *player;

@property (weak, nonatomic) IBOutlet AVPlayerClass *playerView;

(playerView is your view where you want to show it)

NSURL *url = [[NSBundle mainBundle]URLForResource:@"video_name" withExtension:@"mp4"];
_player = [AVPlayer playerWithURL:url];


playerLayer = [AVPlayerLayer playerLayerWithPlayer:_player];
playerLayer.frame = _playerView.bounds;

playerLayer.videoGravity = AVLayerVideoGravityResizeAspectFill;

[_playerView.layer insertSublayer:playerLayer atIndex:0];

_player.actionAtItemEnd = AVPlayerActionAtItemEndNone;
[[NSNotificationCenter defaultCenter] addObserver:self
                                         selector:@selector(playerItemDidReachEnd:)
                                             name:AVPlayerItemDidPlayToEndTimeNotification
                                           object:[_player currentItem]];
[_player play];



-(void)playerItemDidReachEnd:(NSNotification *)notification{

AVPlayerItem *p = [notification object];
[p seekToTime:kCMTimeZero];

}

If you using a ViewController for your player. The best practice is presentingViewController

[self presentViewController:playerViewController animated:YES completion:nil];

if you using xib

PlayerViewController *vc = [[PlayerViewController alloc]
                          initWithNibName:@"PlayerViewController" bundle:nil];
[self.view addSubview:[vc view]];
