WebRTC video chat app

In this tutorial, you will learn how to establish a WebRTC connection using the SAFE Network.

Instead of using a centralized video chat service, such as Skype or Google Hangouts – who can track your location, what you are saying, and to whom, you can use the SAFE Network as a secure channel to exchange connectivity information to establish direct peer-to-peer WebRTC connections.

The SAFE Signaling Demo lets you set up a room and share the room name with someone you want to talk with. You should be able to connect to one another with video, audio and a small instant messaging feature on the left. You can see yourself on the bottom right, your peer is visible in the center. Enjoy!

For now, only the connection establishment is done using the SAFE Network. The actual connection is either peer-to-peer (STUN) or via a TURN server. At some point later, we will integrate this functionality directly in CRUST.
