docker-nginx-rtmp

A Dockerfile installing NGINX, nginx-rtmp-module and FFmpeg from source with default settings for HLS live streaming. Built on Alpine Linux.

• Nginx 1.16.0 (Stable version compiled from source)
• nginx-rtmp-module 1.2.1 (compiled from source)
• ffmpeg 4.2 (compiled from source)
• Default HLS settings (See: nginx.conf)

Usage

Server

• Pull docker image and run:

docker pull alfg/nginx-rtmp
docker run -it -p 1935:1935 -p 8080:80 --rm alfg/nginx-rtmp

or

• Build and run container from source:

docker build -t nginx-rtmp .
docker run -it -p 1935:1935 -p 8080:80 --rm nginx-rtmp

• Run it with fluentd log driver:

mkdir -p /tmp/rec
docker run -it --log-driver=fluentd --log-opt tag='docker.nginx.{{.ID}}' --log-opt fluentd-address=172.17.0.2:24224 -p 1935:1935 -p 8080:80 -v /tmp/rec:/srv/rec --rm --privileged nginx-rtmp

docker build -t nginx-rtmp . 
docker run -it --log-driver=fluentd --log-opt tag='docker.nginx.{{.ID}}' --log-opt fluentd-address=`docker inspect -f '{{range .NetworkSettings.Networks}}{{.IPAddress}}{{end}}' fluentd_web_1`:24224 -p 1935:1935 -p 8080:80 -v /tmp/rec:/srv/rec --rm nginx-rtmp

mpv http://localhost:8080/hls/hello.m3u8

curl http://localhost:8080/dash/hello_720p2628kbs/index.mpd

/tmp/dash/hello_720p2628kbs

Start fluentd

cd fluentd
docker build -t custom-fluentd:latest ./
docker inspect -f '{{range .NetworkSettings.Networks}}{{.IPAddress}}{{end}}' fluentd_web_1
docker-compose up --build

docker run -it --rm --name custom-docker-fluent-logger -v $(pwd)/log:/fluentd/log custom-fluentd:latest

• Number of clients

Use HTTP request http://localhost/nclients?app=myapp&name=mystream to get the number of stream subscribers. This number will be automatically refreshed every 3 seconds when opened in browser or iframe.

• Stream live content to:

rtmp://<server ip>:1935/stream/$STREAM_NAME

SSL

To enable SSL, see nginx.conf and uncomment the lines:

listen 443 ssl;
ssl_certificate     /opt/certs/example.com.crt;
ssl_certificate_key /opt/certs/example.com.key;

This will enable HTTPS using a self-signed certificate supplied in /certs. If you wish to use HTTPS, it is highly recommended to obtain your own certificates and update the ssl_certificate and ssl_certificate_key paths.

I recommend using Certbot from Let's Encrypt.

OBS Configuration

• Stream Type: Custom Streaming Server
• URL: rtmp://localhost:1935/stream
• Stream Key: hello

Watch Stream

• In Safari, VLC or any HLS player, open:

http://<server ip>:8080/live/$STREAM_NAME.m3u8

• Example Playlist: http://localhost:8080/live/hello.m3u8
• VideoJS Player
• FFplay: ffplay -fflags nobuffer rtmp://localhost:1935/stream/hello
