NGINX Stream Server on Raspbian/Ubuntu

By installing an NGINX rtmp server on a Raspbian or Ubuntu SO, OBS can be linked to the server, and from the server to multiple stream platforms.

Step by step to stream on Twitch

  1. Install NGINX and RTMP mod 
    sudo apt-get update
sudo apt-get install nginx libnginx-mod-rtmp
  2. Check correct install of NGINX 
    sudo systemctl start nginx.service
sudo systemctl status nginx.service
  3. Search best server based on location and get full link: https://help.twitch.tv/s/twitch-ingest-recommendation?language=en_US
  4. Create config to RTMP server settings: 
    sudo nano /etc/nginx/rtmp.conf
    Add following lines 
    rtmp {
    server {
        listen 1935; #Default RTMP port
        chunk_size 4096; #Size of chunks

        application live { 
            live on; 
            record off; 
            push rtmp://fra02.contribute.live-video.net/app/{stream_key}; #User Stream key here and link searched before
        }
    }
}
  5. Restart NGINX service sudo systemctl restart nginx.service

Stream on rtmps server (Kick)

The way rtmps works with NGINX is by tunelling stream before send it to the server. You can follow these steps:

  1. Modify RTMP server settings:

    sudo nano /etc/nginx/rtmp.conf

    Add kick line

    rtmp {
    server {
        listen 1935; #Default RTMP port
        chunk_size 4096; #Size of chunks

        application live { 
            live on; 
            record off; 
            #twitch
            push rtmp://fra02.contribute.live-video.net/app/{stream_key}; #User Stream key here
            #kick. port number must match on stunnel accept port
            push rtmp://127.0.0.1:19353/kick/{stream_key}; #User Stream key here
        }
    }
}

  2. Is needed to install stunnel, a SSL encryption wrapper between client and server to encrypt the transmission:

    sudo apt-get install stunnel4

  3. Search best server based on location and get full link: https://kick.com/dashboard/settings/stream

  4. Create a config file to kick stream: sudo nano /etc/stunnel/stunnel.conf Add following lines:

    pid = /var/run/stunnel4/stunnel.pid
output = /var/log/stunnel4/stunnel.log

setuid = stunnel4
setgid = stunnel4

# https://www.stunnel.org/faq.html
socket = r:TCP_NODELAY=1
socket = l:TCP_NODELAY=1

debug = 4

[kick]
client=yes
accept=127.0.0.1:19353
connect=fa723fc1b171.global-contribute.live-video.net:443

  5. Restart stunnel and NGINX services:

    systemctl restart stunnel4.service
systemctl restart nginx.service

Stream on Youtube

  1. On youtube account => Youtube Studio => Create => Go Live
  2. Select Streaming Software
  3. Stream Key and Stream Url are available on the Live Dashboard
  4. Modify RTMP server settings: 
    sudo nano /etc/nginx/rtmp.conf
    Add youtube line 
    rtmp {
    server {
        listen 1935; #Default RTMP port
        chunk_size 4096; #Size of chunks

        application live { 
            live on; 
            record off; 
            #twitch
            push rtmp://fra02.contribute.live-video.net/app/{stream_key}; #User Stream key here
            #kick. port number must match on stunnel accept port
            push rtmp://127.0.0.1:19353/kick/{stream_key}; #User Stream key here
            #youtube
            push rtmp://a.rtmp.youtube.com/live2/{stream_key};
        }
    }
}
  5. Restart NGINX service sudo systemctl restart nginx.service
