Recently I was working on a webRTC project that displays media stream in users browser. However this was only on the client side. What if I want to stream this media to other users browser. As I looked around I found that it was possible by connecting to peers and setting up signalling servers (STUN & TURN). I went through all details that was mentioned on one of the articles on html5rocks website.
I am making use of simplewebRTC but that isn't enough I have to set up my own signalling server in order to be actually able to video chat.
My question is what actually is needed in order to implement a live video chat application embedded within website apart from the api provided by webRTC and how do I set up my own signailling server.
signalmaster was built as a signaling server for simplewebrtc and used by talky.io. It's a node application, start it with "node server.js" and then hook up simplewebrtc to the socket.io endpoint provided.
STUN and TURN servers are not signaling servers. They just help with punching a hole through NAT. The most popular option is rfc-5766-turn-server, restund performs quite well too.
You should provide more detail about your project to get a good answer. Are you planning on making only browser to browser calls? SIP calls? These would be a factor in the signalling server you choose. I went with a SIP signalling server (SIPML5.org) and integrated it with an Asterisk server for call control. This also let me integrate my existing corporate telepresence devices into the PBX. If you want to read up on the basics of signalling and on Webrtc in general Muaz Khan has done some very good work on it.

I am a beginner and I am trying to set up a peer-assisted media streaming system, that will work over the web browser. I wish to a server to 'push' media segments to a few clients and then any of these client browsers to push media segment to other client browsers.
I got to know that HTTP/2.0 can make this possible, but I found examples on a server to a client browser.
I came across WebRTC technology. however, could not find anything like PUSH technique among client browser.
I came across WebSocket technology. I found that it does PUSHing from the only server to the client.
Kindly direct.
You should use WebRTC + Socket or any other signaling media system to do it.
WebRTC will send the media peer to peer and the signaling server should manage which connections to make and when. I've seen similar product on the web yet.
WebSocket is not fast enought to stream media. WebRTC is far better when talking about media.
I am designing a website that requires a host and client websites. The host will set something up (a session), and the clients will connect to that host using an ID specific to that session.
I have considered how I will facilitate that communication, and initially I was going to have both the clients and the host periodically query and update a database which holds the current states of all clients and the host to communicate new options and changes - but then I wondered if it is possible, using javascript [or something], for them to connect and communicate directly?
The communication would be very simple messages - single strings to communicate current state and stuff like that.
Im pretty proficient in javascript/html/css, but am happy to learn if there is something that would do a better job of setting this up.
Thanks!

You could try httprelay.io, requires no additional libraries and can be used for simple http client to client communication.
You're looking for WebRTC, which is the de facto and recommended way of doing peer-to-peer connections through the web with pure Javascript:
WebRTC (Web Real-Time Communication) is an API definition drafted by the World Wide Web Consortium (W3C) that supports browser-to-browser applications for voice calling, video chat, and P2P file sharing without the need of either internal or external plugins.
And yes, before you ask, simple messages can be exchanged as well.
Here is the Mozilla reference explaining WebRTC.
Here is a nice simple tutorial to get you started with the code.
Here is a peer-to-peer chat room with video capabilities built using pure WebRTC as a demo.
Prior to WebRTC, there was no satisfactory decentralised way of doing this.
As the comments indicate, Websockets would have been the right idea if you were going with a centralised system - they facilitate real-time communication between clients and a central host.
Decentralised systems, however, must be implemented using WebRTC - this is the only option on the cards.
I am searching for a way to stream video with webRTC. I am very new to webRTC. I have seen a lot of applications on the web that have p2p video chat. The tutorials I follow explain how WebRTC working for the client, but they do not show what use a backend script. And that's exactly what I'm looking for, a backend script (preferably node.js) that ensures that I can stream live video (getUsersMedia) to the client.

Its really simple to get started, checkout a simple demo here
1.You need a WebRTC supported browser. Chrome and firefox are best at now
A signalling server to exchange a media options. SocketIO with Nodejs
TURN and STUN server to solve NAT and Symmetric NAT (Only if you public)
MCU, if you want to limit the bandwidth usage. It give flexibility to a star network rather than mesh network in normal p2p
Is it possible to use WebRTC Data Channels on Node.js in a way that mimics the functionality of WebSockets except using UDP?
In essence I want to have a server running Node.js with which browser clients can establish a full duplex bi directional UDP connection via JavaScript.
My question is the same as this one from 8 months ago. I repost it because the only answer was :
Yes, in theory you should be able to to do this. However, you'll need a node module that supports WebRTC data channels, so that you can connect to it like any other peer. Unfortunately, scanning through the current modules, I don't see one that implements the data channel.
Any of you know of such a module ? In my search I found some node modules with the words "webrtc" and "datachannel", but they didn't look like what was needed, they looked like they were meant for specific needs.
This project is very active, and seem to undertake the mission of importing the entire WebRTC stack into node.js
There's also this project but it looks pretty inactive.
Would love to know if that was satisfying and if you're doing such a project (as in the question) please link to github :)
We have implemented the exact same thing: a server/client way of using WebRTC. Besides we also implemented data port multiplexing, so that server would only need to expose one data port for all rtcdata channels.
A quick summary of how it is achieved:
We implemented in nodejs, using wrtc library. But the same principal could be applied to other implementations.
The server exposes a control port, so that the client will exchange SDPs with the server for establishing their data channel.
To support data port multiplexing, At the server, we modify both peer's SDK, so that
Client will always connect to the same server ip:data_port
We implement a UDP data proxy inside the server, so that it can be the bridge between the server webrtc engine and the client.

im trying to make a web app that supports multi-user video chatting. ive read an article about webrtc on "getting started with webrtc"
(http://www.html5rocks.com/en/tutorials/webrtc/basics/) and done some demo on codelab. but i still dont really know how to make it a 3-way conferencing call.i dont really know a lot about node.js and socket.io. just started learning them because im trying to build this video web app.
so my question is which part of webrtc or socket.io determines that more than 2 users can join the call? or any resource that you guys get direct me to?
thanks in advance.
WebRTC is peer-to-peer protocol(browser-to-browser) without server,So you must know about my browser i must know about your browser means(your browser codec,public ip,port,etc) then only we can able to communicate,so we are using signalling(socket.io:web socket two way communication protocol send some information about my browser ,and receive some information about you browser ,with nodeJS server then peer connection will establish)
Three user communication is also possible in WebRTC using mesh network,see you send some information to me (browser information) at a same time you send this same information to other peer,when i receive some information about your i will send some information about me to you and other peer,the same thing will happen in other peer also.
Here some detail about mesh network http://en.wikipedia.org/wiki/Mesh_networking
I would say that there are two separate things here. WebRTC needs signaling to setup the peer-to-peer communication between two nodes. I think you are on the right track when using Node.js and Socket.js for this.
But it is not WebRTC (or socket.io) that decides if a third part can join the meeting, it is you that decides this. And this is the other part of the signaling that have little to do with WebRTC.
This meens that you implement functionality like setting up meetingroom, discover available meetingrooms, joining meetingrooms etc. When the three part meeting is up and running, each node will have two peer connections, one to each of the other nodes.
For N users, you need to use a media streamer like Kurento (http://www.kurento.org/)
Then you can build your own multi users webrtc solution such as: https://webrtc-chat.com/ (built on top of Kurento)
I looked at those protocols as well, not sure what node.js and sockets.io can do yet, but I think its a big mistake whatever they are doing, because all you need to do is create one place where multiple users will put their webcam images and then everybody could access the place separately to view all conversations. This has to be quick though because not a problem with video but if signal is slow then its not going to be understandable. I would try something else. I am wondering why they could not solve such an easy concept of multi-conferencing.
I have created a parody of multi-chat on my website, I cannot show you right now, but basically I save frames every 5 seconds of video and then store them (overwrite) the image saved in central folder. When somebody logs in they see all the webcams online (done with PHP). I don't know if this helps but it works and it is similar.
