WebRTCDataMedia - Multimedia through the WebRTC Data Channel

Demo: https://webrtc-stud.uninett.no

• Submit the room name in the prompt.
• Send the link or the room name to a peer.
• Chat with eachother with audio and video through the WebRTC data channel.

This WebRTC system attempts to apply the WebRTC datachannel to transmit uncompressed audio and video between peer-browsers.

The system attempts to mimic how current music collaboration tools transmit audio over IP-nettworks, i.e. uncompressed and unbuffered. The aim is to achieve an audio connection with lower delay (and higher quality) compared to the standard audio channel in WebRTC.

Installation Guide

git clone https://github.com/hungqt/PeerAudio.git

npm install
node local.js

Then open http://localhost:8080 to see your app.

• The server file local.js is used to run localhost, while app.js is deployed to the server.

The system

The system consists of a server and client.

Server

A node.jo server is implemented to provider "rooms" for peers of clients to meet. socket.io is applied to implement room-support and simple "vanilla" forwarding of messages between room-members are performed.

Currently only two member per room is supported.

Server JavaScript-code is in app.js.

Client

After loading the client page requires "vanilla" selection of a room name (of the user choice). When two clients have join a room, audio may be exchanged.

• Batch forwarding: A peer may record an audio clip and forward to the other peer. Receiveing peer may play out the clip.
• Realtime: A peer may initiate a live audiostream

All audio is forwarded across the WebRTC datachannel.

Client JavaScript-code is in js/main.js.

Status

The system is very much under development, and currently not fully implemented.
