This is a demo Erlang app to demonstrate the usage of Janus. For further information regarding "why this demo?" I encourage you to read my blog post Scalable Broadcasting Using WebRTC.

The demo will expose the following endpoints:

• http://localhost:8080/janus-client Client connecting directly to Janus for video broadcast
• http://localhost:8080/api-client Client connecting to our Erlang app
• http://localhost:8080/websocket Endpoint to establish a websocket connetion with our Erlang app.

NOTE: This demo was tested using Firefox 65 and Chrome 72.

• Erlang/OTP (tested with Erlang/OTP 21)
• Docker Compose

First turn on Janus

make ops

Start Erlang app

make run

To stop Janus

make ops_stop

Both clients, janus-client and api-client, present the same interface and way to use so everthing explained below applies to both.

1. Start session
2. Start handle
3. Make room (This will fill the Room ID field)
4. Join as publisher (This will fill the Feed ID field)
5. Start broadcast

To join a broadcast you need to fill the Room ID and Feed ID fields with the values set for the broadcaster.

1. Start session
2. Start handle
3. Join broadcast
