nginx-rtmps

Docker image with Nginx using the nginx-rtmp-module module for streaming and Stunnel to add TLS encryption functionality.

Description

This Docker image can be used to create an RTMP server for multimedia / video streaming using Nginx, nginx-rtmp-module and Stunnel, built from the current latest sources (Nginx 1.18.0 , nginx-rtmp-module 1.2.1 and Stunnel 4).

This was inspired by other similar previous images from tiangolo, dvdgiessen, jasonrivers, aevumdecessus and by an OBS Studio post.

The main purpose (and test case) to build it was to allow streaming from OBS Studio to different clients at the same time.

Details

How to use

• For the simplest case, just run a container with this image:

docker run -it -p 1935:1935 --name nginx-rtmps mach7enterprises/rtmps

• Facebook and Youtube:

docker run -it -p 1935:1935 -e FACEBOOK_KEY=<key> -e YOUTUBE_KEY=<key> mach7enterprises/rtmps

• OBS

rtmp://localhost:1935/live

• Instagram:

docker run -it -p 1935:1935 -e INSTAGRAM_KEY=<key> mach7enterprises/rtmps

• OBS

rtmp://localhost:1935/instagram

How to test with OBS Studio

• Run a container with the command above

• Open OBS Studio

• Click the "Settings" button

• Go to the "Stream" section

• In "Stream Type" select "Custom Streaming Server"

• In the "URL" enter the rtmp://<ip_of_host>/live replacing <ip_of_host> with the IP of the host in which the container is running. For example: rtmp://192.168.0.30/live

• In the "Stream key" use a "key" that will be used later in the client URL to display that specific stream. For example: test

• Click the "OK" button

• In the section "Sources" click de "Add" button (+) and select a source (for example "Screen Capture") and configure it as you need

• Click the "Start Streaming" button

Debugging

If something is not working you can check the logs of the container with:

docker logs nginx-rtmps

Extending

If you need to modify the configurations you can create a file nginx.conf and replace the one in this image using a Dockerfile that is based on the image, for example:

FROM mach7enterprises/rtmps

COPY nginx.conf /etc/nginx/nginx.conf

The current nginx.conf contains:

worker_processes auto;
rtmp_auto_push on;
rtmp_auto_push_reconnect 1s;
events {}
rtmp {
    server {
        listen 1935;
        listen [::]:1935 ipv6only=on;
        chunk_size 4096;

        application live {
            live on;
            record off;
	    #push rtmp://a.rtmp.youtube.com/live2/<key>;
	    #push rtmp://127.0.0.1:19350/rtmp/<key>;
        }

        application instagram {
            live on;
            record off;
            #push rtmp://127.0.0.1:19351/rtmp/<key>;
        }

    }
