AVPlayer狀態始終AVPlayerStatusReadyToPlay

Question

我使用AVPlayer從URL

在viewDidLoad中播放音頻：

self.playerItem = [AVPlayerItem playerItemWithURL:[NSURL URLWithString:imageText]]; 

self.player = [AVPlayer playerWithPlayerItem:playerItem]; 

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

[player play]; 

觀察

- (void)observeValueForKeyPath:(NSString *)keyPath ofObject:(id)object 
         change:(NSDictionary *)change context:(void *)context { 
    if (object == player && [keyPath isEqualToString:@"status"]) { 
     if (player.status == AVPlayerStatusReadyToPlay) { 
      //[playingLbl setText:@"Playing Audio"]; 
      NSLog(@"fineee"); 
      [playBtn setEnabled:YES]; 
     } else if (player.status == AVPlayerStatusFailed) { 
      // something went wrong. player.error should contain some information 
      NSLog(@"not fineee"); 
      NSLog(@"%@",player.error); 

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


     } 
    } 
} 

但球員有時被卡住，並且不播放音頻，但狀態是AVPlayerStatusReadyToPlay。它永遠不會進入AVPlayerStatusFailed或AVPlayerItemStatusUnknown。由於我想處理AVPlayer的錯誤，它也必須進入這些內部。請幫忙！！

您應該觀察CurrentItem的狀態。由於AVPlayerItem失敗，AVPlayer失敗，如果任何事情出錯了，它將從AVPlayerItem開始，然後是AVPlayer。

嘗試：

[item addObserver:self forKeyPath:@"status" options:NSKeyValueObservingOptionNew context:nil]; 

在observeValueForKeyPath

：

if (object == audioPlayer.currentItem && [keyPath isEqualToString:@"status"]) { 
    if (audioPlayer.currentItem.status == AVPlayerItemStatusFailed) { 
     NSLog(@"------player item failed:%@",audioPlayer.currentItem.error); 
    } 
} 

你可以看看的AVPlayer的處理或直接從HysteriaPlayer，我的開源項目中使用它。
