Nginx RTMP拉到HLS流

Question

我遵循了这篇关于将RTMP设置为HLS流的指南-https://docs.peer5.com/guides/setting-up-hls-live-streaming-server-using-nginx/

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链路更改为内部IP和外部IP,因为它可以被访问。我测试了从网络上的另一台计算机观看rtmp，以确认它是正常的。我想避免使用ffmpeg代码转换，因为服务器没有这种功能。

Answer 1

所以我把它整理好了。基本上，我所寻求的是将RTMP转换为HLS，而不需要代码转换。如果其他人看到了这个并需要它，这很简单，但是，您确实需要ffmpeg来完成它。您实际上告诉ffmpeg将流传递给HLS，因为OBS已经是正确的视频/音频格式，所以它将毫无问题地接受它。我使用的命令是

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

这样做对我的CPU几乎没有影响，这正是我所需要的。
