What is WebRTC?

This reads much more like an ad for Pubnub than an explanation of WebRTC. For anyone looking for an introduction to WebRTC, this presentation by Dan Burnett and Alan Johnston showed up in my twitter feed today- http://adhearsionconf.com/events/tbd-6/

I am writing a real time browser game with synchronized physics and would like to use UDP via the data channels in WebRTC to send position data between the users (and also to the Node server) and to make in game audio chat possible.

1. I wasn't able to find demos which do only audio 2. If I don't allow video and only audio in Firefox, none of the demos work at all, I can't hear anything 3. I wasn't able to find any basic example code on how to use data channels 4. Is there a Node module so I could talk to my Node server via data channels (and therefor via UDP) (http://stackoverflow.com/questions/20849039/node-js-module-f...)?

I'd appreciate hints and links to solve any of this problems :)

I wrote this a long time ago when I was beginning to learn webrtc. It's really straightforward and has examples for voice+video chat and voice only. https://github.com/phowat/simple-webrtc-chat. Feel free to drop me an email if you have any questions (it's in my profile here.)

I'm working on para.io [1] which is in this same space, solving the same problems. We should talk!

I'm working on an open-source WebRTC project [0], and my code contains audio-only chat and data channels setup [1] which can hopefully set you on the right path.

I recently played around with WebRTC to let you upload files to MediaCrush directly from your microphone: https://mediacru.sh

Here's the code, if anyone wants to give it a read: https://github.com/MediaCrush/MediaCrush/pull/488

Data channel is going to change everything when it's ubiquitous.

WebRTC is a great idea that will remain an esoteric option, because it will never become a universally supported technology, because Microsoft will never add it to the IE, because they bought Skype. The end.

Seriously though, the chances of Microsoft adding real working WebRTC support to the IE are zero.

You have ideas with WebRTC, try the Bistri APIs : http://developers.bistri.com

Project I worked on that allows users to record music in browser using WebRTC. Because we're using both WebRTC && Web Audio API, it only works in Chrome:

Looks amazing .. I've sent it to some music buddies of mine, I hope you get some new users out of it.

Plugins/effects?

Firefox supports both of these things, so you're basically saying your code is broken.

What if both users are behind a firewall which does not allow them to receive incoming connections?

Then you need a TURN server to proxy the data.

See slides 27 through 36 in the presentation I linked to.

Thanks, that was helpful.
