Question

我正在使用AVPlayer播放来自网址的音频

在ViewDidLoad中：

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

self.player = [AVPlayer playerWithPlayerItem:playerItem];

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

[player play];

观察

- (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");


        }
    }
}

但播放器有时卡住并且不播放音频，但状态也是AVPlayerStatusReadyToPlay。它永远不会进入AVPlayerStatusFailed或AVPlayerItemStatusUnknown。由于我想处理AVPlayer的错误，它也必须进入这些错误。请帮忙!!

您应该观察CurrentItem的状态。由于AVPlayerItem失败，AVPlayer失败，如果出现任何错误，则从AVPlayerItem开始，然后是AVPlayer。

尝试：

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

在observeValueForKeyPath：

中

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

您可以查看AVPlayer的处理方法，也可以直接从我的开源项目HysteriaPlayer中使用它。

AVPlayer状态始终为AVPlayerStatusReadyToPlay
