AVPlayer status always AVPlayerStatusReadyToPlay
提问by user2082760
I am using AVPlayer to play audio from a URL
我正在使用 AVPlayer 从 URL 播放音频
In ViewDidLoad:
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];
Observer
观察员
- (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");
}
}
}
but the player sometimes is stuck and does not play the audio but then also status is AVPlayerStatusReadyToPlay. It never goes inside AVPlayerStatusFailed or AVPlayerItemStatusUnknown. As i want to handle AVPlayer's error, it must go inside these as well. Please help!!
但是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。因为我想处理 AVPlayer 的错误，所以它也必须在这些里面。请帮忙！！

You should observe CurrentItem's status. AVPlayer failed because of AVPlayerItem failed, if anythings went wrong, it begins from AVPlayerItem then AVPlayer.
您应该观察 CurrentItem 的状态。AVPlayer 失败，因为 AVPlayerItem 失败，如果出现任何问题，它从 AVPlayerItem 开始，然后是 AVPlayer。
try:
尝试：
[item addObserver:self forKeyPath:@"status" options:NSKeyValueObservingOptionNew context:nil];
in your observeValueForKeyPath:
在您的observeValueForKeyPath 中：
if (object == audioPlayer.currentItem && [keyPath isEqualToString:@"status"]) {
if (audioPlayer.currentItem.status == AVPlayerItemStatusFailed) {
NSLog(@"------player item failed:%@",audioPlayer.currentItem.error);
}
}
You can take a look of AVPlayer's handling or use it directly from HysteriaPlayer, my open source project.
您可以查看 AVPlayer 的处理方式或直接从我的开源项目HysteriaPlayer 中使用它。
