所以我在处理AVPlayer的缓冲和显示通知时遇到问题
我尝试将NSSNortificationCenter与addObserved一起使用并手动添加观察（您可以在我的代码中看到它），但是它不起作用。所以我需要的是在缓冲区加载时出现通知。期待您的帮助
-(void)initPlayer{
NSURL *url = [NSURL URLWithString:@"https://devstreaming-cdn.apple.com/videos/streaming/examples/img_bipbop_adv_example_ts/master.m3u8"];
_asset = [AVAsset assetWithURL:url];
_player = [[AVPlayer alloc] initWithPlayerItem:[[AVPlayerItem alloc] initWithAsset:_asset]];
[_player addObserver:self forKeyPath:@"path" options: NSKeyValueObservingOptionNew | NSKeyValueObservingOptionInitial context:nil];
[[NSNotificationCenter defaultCenter]addObserver:self selector:@selector(makeNortification:) name:AVPlayerItemPlaybackStalledNotification object:_player];
_layer = [AVPlayerLayer playerLayerWithPlayer:_player];
[_layer setFrame:(self.view.frame)];
[self.view.layer addSublayer:_layer];
[_player play];
[self setSliderMaxValue];
-(void)makeNortification:(NSNotification *) nortification{
NSLog(@"waiting..");
}
-(void)observeValueForKeyPath:(NSString *)keyPath ofObject:(id)object change:(NSDictionary<NSKeyValueChangeKey,id> *)change context:(void *)context{
if (object == _player &&[keyPath isEqualToString:@"status"] ){
if(_player.status == AVPlayerStatusReadyToPlay){
NSLog(@"player is ready");
}
else if(_player.status == AVPlayerStatusUnknown || _player.status == AVPlayerStatusFailed){
NSLog(@"waiting.");
}
else{
}
}
