Nginx RTMP上载到HLS流中

问题描述 投票:0回答:1

我已按照本指南将RTMP设置为HLS流-https://docs.peer5.com/guides/setting-up-hls-live-streaming-server-using-nginx/

RTMP流式传输工作正常,但由于某种原因,我无法让HLS与现有的RTMP服务器链接。我正在使用OBS将数据流传输到RTMP,并将其设置为x264,据我所知,音频的默认编解码器是AAC,所以我不确定为什么不选择它。

当前Nginx.conf

worker_processes  auto;
events {
    worker_connections  1024;
}

# RTMP configuration
rtmp {
    server {
        listen 1935; # Listen on standard RTMP port
        chunk_size 4000;

# Define the Application
        application show {
            live on;
            pull rtmp://localhost:1935/stream/test;
            # Turn on HLS
            hls on;
            hls_path /mnt/hls/;
            hls_fragment 3;
            hls_playlist_length 60;
            # disable consuming the stream from nginx as rtmp
            deny play all;
        }

        # RTMP video on demand for mp4 files
        application vod {
            play /mnt/mp4s;
        }

        # RTMP stream using OBS
        application stream {
            live on;
        }

    }
}

http {
    sendfile off;
    tcp_nopush on;
    aio on;
    directio 512;
    default_type application/octet-stream;

    server {
        listen 8080;

        location / {
            # Disable cache
            add_header 'Cache-Control' 'no-cache';

            # CORS setup
            add_header 'Access-Control-Allow-Origin' '*' always;
            add_header 'Access-Control-Expose-Headers' 'Content-Length';

            # allow CORS preflight requests
            if ($request_method = 'OPTIONS') {
                add_header 'Access-Control-Allow-Origin' '*';
                add_header 'Access-Control-Max-Age' 1728000;
                add_header 'Content-Type' 'text/plain charset=UTF-8';
                add_header 'Content-Length' 0;
                return 204;
            }

            types {
                application/dash+xml mpd;
                application/vnd.apple.mpegurl m3u8;
                video/mp2t ts;
            }

            root /mnt/;
        }
    }
}

我已经尝试将该配置中的rtmp链接也更改为内部IP和外部IP,因为可以访问它。我测试了从网络上的另一台计算机观看rtmp,以确认其功能正常。我想避免使用ffmpeg进行代码转换,因为服务器没有这种功能。

ffmpeg http-live-streaming rtmp obs

所以我整理了一下。基本上,我要寻找的只是将RTMP转换为HLS,而无需进行转码。如果其他人看到了这个并且需要它,这很简单,但是,您确实需要ffmpeg来实现它。从本质上讲,您告诉ffmpeg将流传递给HLS,并且由于OBS已经是正确的视频/音频格式,它将毫无问题地将其接收。我使用的命令是

ffmpeg -re -i rtmp://localhost:1935/stream/test -codec copy -f flv /mnt/hls/stream.m3u8

以这种方式执行对我的CPU几乎没有影响,而这正是我所需要的。
