Question

我有一个 iOS 流媒体应用程序。它非常适合我的流媒体网址。如何将 AudioStreamer 用于 .m3u8 文件 URL？

提前致谢

虽然 AudioStreamer 使用 AVPlayer 可以很容易地使用 AVPlayer ，但为什么需要使用 AudioStreamer 类> 内部。

以下代码使用 AVPlayer 播放实时流音频，您可以更改源 URL 以嵌入您的流。

Don't forget to add AVFoundation.framework in your Linked Frameworks and Libraries section under Project->Target->Linked Frameworks and Libraries

#import "ViewController.h"
#import <AVFoundation/AVFoundation.h>

@interface ViewController ()
{
    AVPlayerItem * mPlayerItem;
}

@property (readwrite, retain, setter=setPlayer:, getter=player) AVPlayer* mPlayer;
@property (strong) AVPlayerItem *mPlayerItem;

@end

@implementation ViewController

@synthesize mPlayer;
@synthesize mPlayerItem;

- (void)viewDidLoad {
    [super viewDidLoad];
    // Do any additional setup after loading the view, typically from a nib.

    // *** Initialise player and register observer ***
    NSURL *url = [NSURL URLWithString:@"http://devimages.apple.com/iphone/samples/bipbop/bipbopall.m3u8"];

    self.mPlayerItem = [AVPlayerItem playerItemWithURL:url];

    self.mPlayer = [AVPlayer playerWithPlayerItem:self.mPlayerItem];

    // *** Add Observer on AVPlayerItem to observer progress & status ***
    [self.mPlayerItem addObserver:self forKeyPath:@"status" options:NSKeyValueObservingOptionNew context:nil];

    [self.mPlayer play];
}

- (void)observeValueForKeyPath:(NSString *)keyPath ofObject:(id)object
                        change:(NSDictionary *)change context:(void *)context
{
    if (object == self.mPlayerItem && [keyPath isEqualToString:@"status"])
    {
        if (self.mPlayer.currentItem.status == AVPlayerItemStatusFailed)
        {
            NSLog(@"------player item failed:%@",self.mPlayer.currentItem.error);
        }
        else if (self.mPlayer.currentItem.status == AVPlayerStatusReadyToPlay)
        {
            NSLog(@"Play");
            [self.mPlayer play];
        }
        else if (self.mPlayer.currentItem.status == AVPlayerStatusFailed)
        {
            // something went wrong. player.error should contain some information
            NSLog(@"Unable to play.");
            NSLog(@"%@",self.mPlayer.error);
        }
        else if (self.mPlayer.currentItem.status == AVPlayerItemStatusUnknown)
        {
            NSLog(@"AVPlayer Unknown");
        }
    }
}

我希望它能帮助你理解，在给定的代码中，你可以用 AVPlayer 做很多事情。快乐编码:)
