无法流式传输.m3U8文件

Question

I have an iOS streaming app. It works fine for my streaming urls. How can I use AudioStreamer for .m3u8 file url?

Thank you in advance

Why you need to use AudioStreamer class when you can do it with AVPlayer easily, Though AudioStreamer uses AVPlayer internally.

Following code plays live streaming audio using AVPlayer , you can change source URL to embed your stream.

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");
        }
    }
}

I hope it helps you to understand, there are lot of stuffs you can do with AVPlayer in given code. Happy coding :)

Try and parse the m3u8 file and get the actual URL to the resource and then pass that URL to AudioStreamer.

Here -> https://github.com/Achillesun/M3U8Paser you can find M3U8Parser lib that parse the playlist.

Below is an example of m3u8 format:

#EXTM3U
#EXT-X-TARGETDURATION:10

#EXT-X-MEDIA-SEQUENCE:1

#EXTINF:10,
http://video.example.com/segment0.ts
#EXTINF:10,
http://video.example.com/segment1.ts
#EXTINF:10,
http://video.example.com/segment2.ts
#EXT-X-ENDLIST
