Create your own streaming server with nginx<\/mark><\/h1>\n\n\n\n

FWD: CamOn Living Streaming<\/a><\/p>\n\n\n\n\n\n

Note: Have been verified on Redmi-6\/MiUi 14, and openresty + RTMP Module + Linux<\/strong><\/em><\/p>\n\n\n\n

<\/p>\n\n\n\n

We saw how to setup a streaming server with MistServer in this post<\/a>, let’s see how to do the same with nginx<\/strong><\/a>.<\/p>\n\n\n\n

nginx, pronounced “engine X<\/em>“, is a web server that can also be used as a reverse proxy, load balancer, mail proxy, HTTP cache and, why not, RTMP server. It is free and open-source software, released under the terms of the 2-clause BSD<\/a> license.<\/p>\n\n\n\n

For the purpose of this trial, we will see how to install and configure the server on a Raspberry Pi board running Raspberry Pi OS Lite<\/strong>.<\/p>\n\n\n\n

\n\n\n\n

Install nginx with RTMP support<\/h3>\n\n\n\n

First, we must install the server and an add-on module that will allow it to handle the RTMP protocol. sudo apt install nginxsudo apt install libnginx-mod-rtmp<\/p>\n\n\n\n

After the installation is complete, we should be able to reach the welcome page simply by entering the IP address of the server in our favorite browser, http:\/\/192.168.1.18\/ for us.<\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n
\n\n\n\n

Configure the RTMP server<\/h3>\n\n\n\n

The way nginx and its modules work is determined in the configuration file. By default, the configuration file is named nginx.conf<\/em> and placed in the directory \/etc\/nginx<\/em>. For details, please check out the Beginner\u2019s Guide<\/a> and other resources available in the nginx documentation<\/a>.<\/p>\n\n\n\n

To enable the RTMP protocol, edit the configuration file sudo nano \/etc\/nginx\/nginx.conf<\/p>\n\n\n\n

then add these few lines at the very end #<\/strong> protocol imap; #<\/strong> proxy on; #<\/strong> } #<\/strong>}
rtmp { server { listen 1935; application live { live on;
hls on; hls_path \/tmp\/hls; } } }<\/p>\n\n\n\n

finally save the file and restart the server so that the new configuration will be loaded sudo nginx -s reload<\/p>\n\n\n\n

In this example, we are configuring the RTMP server to listen on the port 1935<\/strong> (the default RTMP port), and to handle an application named live<\/em><\/strong>. This application has the live mode<\/strong> (one-to-many broadcasting) enabled. The HLS output<\/strong> is also enabled, the playlist and the fragments will be saved in \/tmp\/hls<\/em> (if the directory does not exist it will be created).<\/p>\n\n\n\n

The complete reference about the available RTMP directives can be found here<\/a>.<\/p>\n\n\n\n

\n\n\n\n

Configure the HTTP server<\/h3>\n\n\n\n

We need to configure the HTTP server so that it can access the files in \/tmp\/hls<\/em> for clients to play HLS. nginx uses the so called Server Blocks<\/em> to serve multiple sites in parallel, let’s change the configuration of the default one sudo nano \/etc\/nginx\/sites-enabled\/default<\/p>\n\n\n\n

by adding a new location<\/a> entry according to the documentation<\/a> location \/ { # First attempt to serve request as file, then # as directory, then fall back to displaying a 404. try_files $uri $uri\/ =404; } location \/hls { types { application\/vnd.apple.mpegurl m3u8; } root \/tmp; add_header Cache-Control no-cache; add_header Access-Control-Allow-Origin *; } # pass PHP scripts to FastCGI server #<\/p>\n\n\n\n

then save the file and restart the server once again sudo nginx -s reload<\/p>\n\n\n\n

\n\n\n\n

Configure the app<\/h3>\n\n\n\n

From CamON Live Streaming app settings, enable the Live streaming<\/em><\/strong> adapter and configure it<\/p>\n\n\n\n
