AVPlayer状态始终为AVPlayerStatusReadyToPlay

Question

我正在使用AVPlayer播放来自URL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");


        }
    }
}

但播放器有时会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!!

你应该观察CurrentItem的状态.由于AVPlayerItem失败,AVPlayer失败,如果出现任何错误,它从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);
    }
}

你可以看看AVPlayer的处理,或者直接从我的开源项目HysteriaPlayer中使用它.
