WebRTC allows real-time communications within the browser without the need for plugins. A few of its greatest benefits include:
- Standardized methods of connecting to web cameras and microphones.
- Peer to peer connections. Improves latency and reduces bottlenecks on the servers.
- Standardized negotiation for streaming audio, video and data.
EasyRTC removes the pain associated with getting started with WebRTC with the following cool features:
- Cross browser support.
- Working source code.
- Easy server install.
- WebSocket server.
- Single language for server and clients (JavaScript).
- Open Source and free!
The WebRTC API is a mid-level API. That is to say, that while it insulates the developer from stuff like connecting to cameras or contacting TURN and STUN servers, it still requires the developers to implement an involved message passing scheme between clients to establish the peer to peer connection.
The EasyRTC framework provides that message passing scheme so that the developer can focus on the tasks that are actually relevant to them.
So far we have tested EasyRTC on Windows 7, 8, OS-X, Raspberry Pi, and Ubuntu 12.04 LTS where users have administrator or sudo access.
For the most part, if you can run Node.JS, you can run EasyRTC.
We have used EasyRTC in production since May of 2013 (see https://tawk.com). The included demos include notes about what browsers the various features work in, or how experimental the feature is.
There is a lot of work still to go in providing additional features which production code will need. We invite all users to give us feedback as to what features you desire.
Many products and services utilizing WebRTC have already been released despite the specification not yet being finalized. The original posted date for reaching recommendation status was overly optimistic (Q1 2013). With implementation methods still being debated, be prepared for it to take until Q4 2014 (or longer).
As the specification gets closer to recommendation status, we expect those browsers which are currently working on WebRTC to better communicate with each other. Currently the biggest contended issues surround video codec requirements.
Some browsers may wait until after the standard reaches recommendation status to implement WebRTC.
The data channel portion of the specification is close to being finalized. Browser support is getting better, with inter-optibility among desktop Chrome and Firefox now possible.
EasyRTC supports automatic fail-over to websockets in those cases where data channel support is spotty.
EasyRTC includes a demo showing up to four connections in a star configuration. Each peer establishes a connection to every other peer.
Check out tawk.com for an in-production example.
More advanced conference and multicast requirements would require a dedicated WebRTC capable conference server or MCU. EasyRTC does not yet include direct support for these. We are working with various vendors to gain this support.
Node.JS is a powerful asynchronous server platform which has several qualities we find enduring:
- Performs exceptionally well as a HTML5 socket server.
- Easy to program for with a thriving open source community to back it up.
- Multi-platform! Allows installs on Linux, Windows, and Macs.
- The Node Package Manager provides an easy way to distribute and install EasyRTC.
SIP is an extensive protocol, and developing a WebRTC platform which supports it in a way casual developers could use it would be difficult. Unless we can come up with a way to make this "easy", it won't happen. This does allow for SIP and VOIP gateways to implement WebRTC using EasyRTC.
Priologic Software has been working on SIP integration methods commercially (shameless plug).
