Question

我在聊天应用程序中使用AVPlayer但是我在选定的音频文件中遇到了错误但是音频文件在浏览器中正确播放。

错误域= AVFoundationErrorDomain代码= -11800“操作可以未完成“UserInfo = {NSUnderlyingError = 0x60800024fde0 {错误 Domain = NSOSStatusErrorDomain Code = -16170“（null）”}， NSLocalizedFailureReason =发生未知错误（-16170）， NSLocalizedDescription =无法完成操作}

我正在实施以下方法。

-(void)setupAVPlayerForURL:(NSURL*)url
 {
    AVAsset *asset = [AVURLAsset URLAssetWithURL:url options:nil];
    AVPlayerItem *anItem = [AVPlayerItem playerItemWithAsset:asset];
    playerAud = nil;
    playerAud = [AVPlayer playerWithPlayerItem:anItem];
    [self startTimer];
    [playerAud play];
    [anItem addObserver:self forKeyPath:@"status" options:NSKeyValueObservingOptionNew context:nil];
    [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(stopAudioPlay) name:AVPlayerItemDidPlayToEndTimeNotification object:nil];
}

And also implement the fallowing observer.

- (void)observeValueForKeyPath:(NSString *)keyPath ofObject:(id)object change:(NSDictionary *)change context:(void *)context
{
    //// playerAud is instance of AVPlayer 
    if (object == playerAud.currentItem && [keyPath isEqualToString:@"status"]) {
        if (playerAud.currentItem.status == AVPlayerItemStatusFailed) {
            NSLog(@"------player item failed:%@",playerAud.currentItem.error);
        }
    }
}

It prints the above error.
