无法流式传输.m3U8文件

Question

我有一个iOS流媒体应用程序。它适用于我的流媒体URL。如何将AudioStreamer用于.m3u8文件url？

提前感谢

为什么你需要使用AudioStreamer类，而你可以很容易地使用AVPlayer，尽管AudioStreamer在内部使用AVPlayer。

以下代码使用AVPlayer播放直播音频，您可以更改源URL以嵌入流。

不要忘记在项目->目标->链接框架和库下的Linked Frameworks and Libraries部分添加AVFoundation.framework

#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：）

尝试解析m3u8文件，获取资源的实际URL，然后将该URL传递给AudioStreamer。

此处->https://github.com/Achillesun/M3U8Paser您可以找到解析播放列表的M3U8Parser库。

以下是m3u8格式的示例：

#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
