从另一个流中检索HLS数据并将其推送到rtmp服务器。

Question

我一直在做一个项目，在这个项目中，我需要能够动态地推送到其他两个或三个频道。我测试了几种场景，最后一次尝试如下：

流服务器

worker_processes auto;
rtmp_auto_push on;
events {}
rtmp {
    server {
        listen 1935; # Listen on standard RTMP port

        application live {
            live on;
            hls on;
            hls_path /www/tmp/hls;
            hls_fragment 10s; # default is 5s
            hls_playlist_length 5m; # default is 30s
            # once playlist length is reached it deletes the oldest fragments

            # authentication
            # on_publish => some other server
            # on_done => some other server
        }
    }
}

http {
    server {
        listen 8080;

        location /hls {
            types {
                application/vnd.apple.mpegurl m3u8;
                application/octet-stream ts;
            }
            root /www/tmp;
            add_header Cache-Control no-cache;

            # To avoid issues with cross-domain HTTP requests (e.g. during development)
            add_header Access-Control-Allow-Origin *;
        }
    }
}

然后强制另一个服务器从该服务器创建的hls内容中读取。我尝试过使用节点媒体服务器和nginx，但在这方面都没有真正的解决方案，下面是我在nginx上的尝试：

events {}
rtmp {
    server {
        listen 1935; # Listen on standard RTMP port
        chunk_size 4000; 
        # ping 30s;
        # notify_method get;

        # This application is to accept incoming stream
        application live {
            live on; # Allows live input
            deny play all; # disable consuming the stream from nginx as rtmp

            hls on; # Enable HTTP Live Streaming
            hls_fragment 3;
            hls_playlist_length 10;
            hls_path /www/tmp/hls;  # hls fragments path
                        
            # MPEG-DASH
            dash on;
            dash_path /mnt/dash/;  # dash fragments path
            dash_fragment 3;
            dash_playlist_length 10;    
            push => another rtmp server;
        }
    }
}

http {
    server {
        listen 8080;

        location / {
            root /www;
        }

        location /hls {
            types {
                application/vnd.apple.mpegurl m3u8;
                application/octet-stream ts;
            }
            root /tmp;
            add_header Cache-Control no-cache;

            # To avoid issues with cross-domain HTTP requests (e.g. during development)
            add_header Access-Control-Allow-Origin *;
        }
    }
}

如果您知道任何其他选择，请让我知道或有任何其他建议，谢谢

Answer 1

你想这样做吗？

Client -----> Nginx -------> Server
         (Stream 1/2/3)    (Stream 2)

您不应该让另一台服务器从Nginx读取Stream 2，整数您应该使用FFmpeg作为客户端这样做：

Client -----> Nginx -----> FFmpeg  --> Server
         (Stream 1/2/3)             (Stream 2)

要做到这一点，请像这样运行命令：

ffmpeg -f flv -i rtmp://ip/live/stream2 -c copy -f flv rtmp://server/live/stream2

因此，您可以将任何流从Nginx读取到另一台服务器。

如果您希望Server执行此操作，则可以使用SRS/Ingest，该SRS/Ingest叉一个FFmpeg进程将流拉到SRS

Answer 2

@Winlin for Nginx上面提到的解决方案将有效，而且由于问题是关于Nginx I的，所以将其标记为批准的答案，

一般来说，ffmpeg是关键，我也尝试了，而ffmpeg是推荐的方法。

我的设置的样例配置：

const config = {
    rtmp: {
      port: 1937,
      chunk_size: 60000,
      gop_cache: true,
      ping: 30,
      ping_timeout: 60,
    },
  
    relay: {
      ffmpeg: "/bin/ffmpeg",
      tasks: [
        {
          name: "XXXXX",
          app: "live",
          mode: "static",
          edge: "rtmp://rtmp_server:1935/live/test", // my other server
        },
        {
          app: "live",
          name: "XXXXX",
          mode: "push",
          edge: "rtmp://live.twitch.tv/app", // twitch server
        },
      ],
    },
  };
