Question

我想在AvPlayer中播放远程.mp4视频。这是我的代码

 NSString *encodedString = [urlString stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding];
 NSURL *videoUrl = [[NSURL alloc]initWithString:encodedString];
 self.asset = [AVAsset assetWithURL:videoUrl];
 self.player = [AVPlayer playerWithURL:videoUrl];
 self.player.actionAtItemEnd = AVPlayerActionAtItemEndNone;

 self.playerLayer = [AVPlayerLayer playerLayerWithPlayer:self.player];
 self.playerLayer.videoGravity = AVLayerVideoGravityResizeAspectFill;

[self.player addObserver:self forKeyPath:@"status" options:0 context:nil];


[[NSNotificationCenter defaultCenter] addObserver:self
                                         selector:@selector(playerItemDidReachEnd:)
                                             name:AVPlayerItemDidPlayToEndTimeNotification
                                           object:[self.player currentItem]];



self.playerLayer.frame = CGRectMake(0, 0, self.view.frame.size.width, self.view.frame.size.height);
[self.myPlayerView.layer addSublayer:self.playerLayer];



self.videoPlaybackPosition = 0;

[self.player play];



- (void)observeValueForKeyPath:(NSString *)keyPath ofObject:(id)object change:(NSDictionary *)change context:(void *)context {

   if (object == self.player && [keyPath isEqualToString:@"status"]) {
    if (self.player.status == AVPlayerStatusFailed) {
        NSLog(@"AVPlayer Failed --> %ld",(long)self.player.currentItem.status);

    } else if (self.player.status == AVPlayerStatusReadyToPlay) {
        NSLog(@"AVPlayerStatusReadyToPlay");

        [self.player play];


    } else if (self.player.status == AVPlayerItemStatusUnknown) {
        NSLog(@"AVPlayer Unknown");

    }
  }
}

AVPlayerStatusReadyToPlay需要一些时间来缓冲视频，它只能工作一次。但是我使用相同的代码录制视频并从临时文件播放。在那种情况下它工作正常。将视频上传到服务器后，当我尝试从服务器播放视频时，视频播放仅1-2秒。之后视频卡住，没有任何反应。我无法理解我的问题在哪里。

任何人都可以帮帮我吗？
