m3u8 流媒体无法在 Apple tv 上运行（airplay）答案

【问题标题】：m3u8 streaming not working on apple tv (airplay)m3u8 流媒体无法在 Apple tv 上运行（airplay）

【问题描述】：

我正在为我的 m3u8 流媒体使用 AVPlayer，该流媒体在 iphone 和 ipad 设备上运行良好，但是当我尝试通过 Airplay 在 Apple Tv 上播放该流媒体时，它无法正常工作，我为 AppleTv 设置了 AVPlayer，如下所示：

NSURL *url = [NSURL URLWithString:@"//m3u8 path here"]; AVPlayerItem *playerItem = [AVPlayerItem playerItemWithURL:url];

self.videoPlayer = [AVPlayer playerWithPlayerItem:playerItem];
self.playerLayer  = [AVPlayerLayer playerLayerWithPlayer:self.videoPlayer];
[self.playerLayer setFrame:self.view.frame];
[self.view.layer addSublayer:self.playerLayer];
[self.videoPlayer play];
[self.videoPlayer setAllowsExternalPlayback:YES];
self.videoPlayer.usesExternalPlaybackWhileExternalScreenIsActive = YES;

将我的手机与 Apple Tv 连接后，我运行上述代码，然后 Apple tv 开始加载，完成加载后，我只能在电视上看到第一张流媒体图片，然后停止卡住我不知道为什么卡住了尝试很多其他 m3u8 链接，但每个链接都卡在 Apple tv 上，所以任何人都可以帮助我并告诉我哪里出了问题.....谢谢

【解决方案1】：

我可以在 ios 上播放 m3u8 流。

这里是示例代码：

@property (weak, nonatomic) IBOutlet UIView *playerView;
@property (nonatomic, strong) AVURLAsset *asset;
@property (nonatomic, strong) AVPlayer *player;
@property (nonatomic, strong) AVPlayerItem *playerItem;

- (IBAction)startStopForwardingVideo:(id)sender
{
    _asset = [AVURLAsset URLAssetWithURL:[NSURL URLWithString:@"http://******sl.m3u8 live stream url"] options:nil];
    NSError *error = nil;
    self.playerItem = [AVPlayerItem playerItemWithAsset:_asset];
    [self.player addObserver:self forKeyPath:@"status" options:NSKeyValueObservingOptionNew context:AVPlayerItemStatusContext];

    self.player = [[AVPlayer alloc] initWithPlayerItem:self.playerItem];
    AVPlayerLayer *playerLayer = [AVPlayerLayer playerLayerWithPlayer:self.player];

    playerLayer.frame = CGRectMake(0, 0,  self.playerView.frame.size.width,  self.playerView.frame.size.height);
    playerLayer.videoGravity = AVLayerVideoGravityResizeAspectFill;
    [_playerView.layer addSublayer:playerLayer];
}

- (void)observeValueForKeyPath:(NSString *)keyPath ofObject:(id)object change:(NSDictionary *)change context:(void *)context
{
    if ([keyPath isEqualToString:@“status”]) {

            AVPlayerStatus status = [change[NSKeyValueChangeNewKey] integerValue];
            switch (status) {
                case AVPlayerItemStatusUnknown:
                    break;
                case AVPlayerItemStatusReadyToPlay:
                {
                    [self.player play];
                }
            break;
        case AVPlayerItemStatusFailed:
            [self stopLoadingAnimationAndHandleError:[[self.player currentItem] error]];
            break;
            }
    }
}

希望对你有用

它在 ios 上工作我说的是 Apple Tv 在我使用 Airplay @Punita 时无法在 Apple Tv 上工作

【解决方案2】：

此代码适用于 AppleTV，使用 Swift 4.2 和 Xcode10

import UIKit
import AVKit
class ViewController: UIViewController {
    var playerController: AVPlayerViewController!
    var asset: AVURLAsset!
    var playerItem: AVPlayerItem!
    var player: AVPlayer!
    private var playerItemContext = 0
    override func viewDidLoad() {
        super.viewDidLoad()
        self.play()
    }
    func play() {
        let url: URL = URL(string: "https://s3-us-west-2.amazonaws.com/hls-playground/hls.m3u8")!
        asset = AVURLAsset(url: url)
        let playerItem = AVPlayerItem(asset: asset)
        player = AVPlayer(playerItem: playerItem)
        playerItem.addObserver(self, forKeyPath: #keyPath(AVPlayerItem.status), options: NSKeyValueObservingOptions.new, context: &playerItemContext) // AVPlayerItem.Status.readyToPlay)
        let playerLayer = AVPlayerLayer(player: player)
        playerLayer.frame = self.view.bounds
        playerLayer.videoGravity = AVLayerVideoGravity.resizeAspectFill
        self.view.layer.addSublayer(playerLayer)
    }
    override func observeValue(forKeyPath keyPath: String?, of object: Any?, change: [NSKeyValueChangeKey : Any]?, context: UnsafeMutableRawPointer?) {
        if keyPath == #keyPath(AVPlayerItem.status) {
            if let change = change {
                if let status = change[NSKeyValueChangeKey.newKey] {
                    switch status as! Int {
                    case 0: //AVPlayerItem.Status.unknown:
                        break
                    case 1: //AVPlayerItem.Status.readyToPlay:
                        player.play()
                    default:
                        break
                    }
                }
            }
        }
    }
}

您可以更改为您喜欢的 *.m3u8 播放列表我希望它有帮助...e
