我在聊天应用程序中使用 AVPlayer,但在选定的音频文件中遇到以下错误,但音频文件在浏览器中正确播放。
错误域=AVFoundationErrorDomain代码=-11800“该操作可以
未完成” UserInfo={NSUnderlyingError=0x60800024fde0 {Error
域=NSOSStatusErrorDomain代码=-16170“(空)”},
NSLocalizedFailureReason=发生未知错误(-16170),
NSLocalizedDescription=操作无法完成}
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.
就我而言,我使用 http url.SetNSAllowsArbitraryLoads to YES
修复错误。
