WebRTC Basic
Simplest demo by using basic methods and events in the WebRTC
Prepare
- one pc ( with camera and mic ) and one mobile devices(or any Mobile-UA client)
- solid network
concepts
ICE
Interactive Connectivity Establishment (ICE) is a technique used in computer networking to find ways for two computers to talk to each other as directly as possible in peer-to-peer networking.— WIKIPEDIA
Namely, it’s a protocol can help you connect to another client.
Peer
similarly with the word peer in the Peer to Peer download. it could be a client ˜ or a browser page or a Native-App.
Signaling server
before your peer transfers data through STUN/TURN server, you need to tell others your existing, signaling server can help.
STUN/TURN server
A STUN client can send messages to the STUN server to get the information about public IP and ports, and retrieve that information.

the communication between two client’s may complicated: ip, DNS, transport protocol and so forth. STUN/TURN are most direct way to handle connection between peers, i.e. public ip and port.
Streams
Streams are exactly content what you want been transferred. It could be a media caught from UserMedia API or playable video and so forth.
Events
these are base lifecycle of the rtc-peer connect to other peers.

comprehension
Imagine that the whole process of the WebRTC just like you ask your friend to get your crush’s number so you can call her.
If you screw it up, you are negotiationneeded, so you can start your new life.
