Why ,are we here ?

Web real time communication

Why Webrtc ?

Webrtc is a free, open project that enables web browsers with real-time communication(RTC) capabilities via simple javascript APIS

No plugin required

(i,e need not install and configure software everytime)

Platform and system independent

Just need to have the latest version of chrome / mozilla

(i,e clients are our web browser.)

User and developer friendly , video chat experience can be built using 100 lines of JS code

Architecture & Working

Simple architecture ready to use APIs

1. getUserMediaStream API

- for accessing webcam and microphone

2. PeerConnection API

-connecting to other end user(remote peer)

3. Datachannel API

- screen sharing , gaming , text chat ,file transfer

Disadvantages !

Need to implement signalling for connecting 2 browser

Apple web-browser Safari yet to support webrtc APIs . We might need a native app on IOS platforms

Internet Explorer (IE) is building its own Webrtc APIs named CU-RTC-Web

Various browsers use different APIs for WEBRTC implementation

browsers supported at present
