Question

我有一个iOS流媒体应用。它适用于我的流媒体网址。如何将AudioStreamer用于.m3u8文件网址？

提前谢谢

为什么您需要使用AudioStreamer课程才能轻松使用AVPlayer课程，尽管AudioStreamer在内部使用AVPlayer。

以下代码使用AVPlayer播放实时流媒体音频，您可以更改源网址以嵌入您的信息流。

不要忘记在项目 - ＆gt;目标 - ＆gt;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");
        }
    }
}

我希望它能帮助您理解，在给定的代码中，您可以使用AVPlayer执行许多操作。快乐的编码：）

尝试并解析m3u8文件并获取资源的实际URL，然后将该URL传递给AudioStreamer。

此处 - ＆gt; 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

无法流式传输.m3U8文件
