rtmp-auth

Simple stream auth backend for:

• nginx-rtmp
• srtrelay
• srs

Features

• Expiring auth
• Single static binary
• Persists state to simple file (no database required)
• Web-UI with subpath support

In the future I might also add support for removing active streams when they expire.

Build Dependencies

• protoc with go-support
• statik go install github.com/rakyll/statik

Usage

Build the daemon with

make

Then start it

./rtmp-auth -app "myrtmp" -apiAddr "localhost:8000" -frontendAddr "localhost:8082"

It will now authenticate streams for the rtmp-app "myrtmp" (the app is the "directory" part of a rtmp url) like rtmp://<host>/<app>/<stream>

Nginx-RTMP

Add on_publish/on_publish_done callbacks to your nginx-rtmp config

application myrtmp {
  live on;
  meta copy;

  hls off;

  allow publish all;
  allow play all;

  # add this for authentication
  on_publish http://127.0.0.1:8080/publish;
  on_publish_done http://127.0.0.1:8080/unpublish;
}

srtrelay

Change the auth to "http" in your srtrelay config and add the api url:

[auth]
type = "http"

[auth.http]
url = "http://localhost:8080/publish"

srtrelay doesn't currently support unpublish.

SRS

Add the http_hooks config inside your srs vhost config:

vhost __defaultVhost__ {
    ...
    http_hooks {
        enabled         on;
        on_publish      http://172.17.0.1:8080/publish;
        on_unpublish    http://172.17.0.1:8080/unpublish;
    }
    ...
}

WebUI

Note: You will need to set the -insecure flag when testing over http.

After reloading your nginx/srs the rtmp publish-requests will be authenticated against the daemon. You can visit http://localhost:8082 to add streams.

For production usage you will want to deploy the frontend behind a Reverse-Proxy with TLS-support like nginx.

Publish a stream

Now that you have set up your software you can start publishing streams

# publish without auth
ffmpeg -i test.mp4 -c copy -f flv rtmp://server/app/stream

# publish with auth
ffmpeg -i test.mp4 -c copy -f flv rtmp://server/app/stream?auth=foobar2342
