- 2. Introduction SkyViewer is a fast in-browser solution for video chatting. SkyViewer makes use of WebRTC to achieve the in-browser functionality. WebRTC (Web Real-Time Communication) is an API definition drafted by the World Wide Web Consortium (W3C) that supports applications for voice calling, video calling, and P2P file sharing without the need of either internal or external plugins. It supports Google Chrome, Mozilla Firefox, Opera, Android, and iOS.
- 3. Motivation ■ Current video chatting solutions (Skype, Hangouts, WebEx, GoToMeeting etc.) require the users or participants to download/install any extension or application. ■ WebRTC is natively supported by most popular browsers hence, we can use this as an advantage. ■ We wanted to create a website that would allow users to seamlessly video chat without any hassle.
- 4. WhyWebRTC? 1. It’s free. 2. Platform and device independent. 3. Advanced voice and video quality: Opus codec for voice and VP8 codec for video. 4. Secure voice and video: WebRTC uses SRTP (Secure Real-time Transport Protocol) for encryption and authentication. 5. Adaptive to network conditions: WebRTC supports the negotiation of multiple media types and endpoints.
- 5. Non-Technical Project Overview 1. Alice and Bob want to video chat. SkyViewer will achieve this in- browser without the need to download or install any software, extension, or plugin. 2. Both of them open the SkyViewer website and they are presented with a field to enter a temporary username (Note that neither of them need to login or create an account). 3. Bob shares his username with the Alice. Alice can now enter the username of Bob in the field and press on ‘Call’. 4. Both the hosts are connected via P2P. 5. The username is deleted once the tab/window is closed or the session expires.
- 6. HowWebRTC works? ■ SessionTraversal of UDP through NAT (STUN) ■ Traversal Using Relay NAT (TURN) ■ Interactive Connectivity Establishment (ICE)
- 7. Implementation We have used the following modules along with a simple HTML website: pubnub.js (Online service): Connection establishment, parameter satisfaction, check conditions and send encrypted key to other user webrtc.js: Instantiate session, video id of camera with permission, sync stream, media configuration, session handling, and defines ICE servers rtc-controller.js: Used for user join, call, leave, video, audio, and integrate with ICE server
- 8. Changelog ■ V1.0: Simple calling. No mute, end, pause. ■ V1.02: Added mute and pause button. ■ V1.03: Multiple callers, ■ V1.04: Change in makemycall function. ■ V1.05: Key changed to default. Multiple Access through same username disallowed. ■ V1.06 : Styling.
- 9. Future Improvements ■ Accept/decline call ■ Instant messaging ■ File sharing ■ Remote Desktop access
