This is a simple project for a live video chat application. It is built using the WebRTC technology.

For those who struggling:

• WebRTC is a free, open-source project that provides web browsers and mobile applications with real-time communication (RTC) via simple application programming interfaces (APIs).
• Socket.io is a library that enables real-time, bidirectional and event-based communication between web clients and servers.

WebRTC

Description

1. getUserMedia: The getUserMedia method prompts the user for permission to use a media input which produces a MediaStream with tracks containing the requested types of media.
2. RTCPeerConnection: The RTCPeerConnection interface represents a WebRTC connection between the local computer and a remote peer. It provides methods to connect to a remote peer, maintain and monitor the connection, and close the connection once it's no longer needed.

WebRTC Flow

1. Signaling: Exchange of information to establish a connection. This can be done using Socket.io or any other method.
2. Offer: The RTCPeerConnection creates an offer which includes information about any MediaStream tracks attached to the connection, codec and media format information, and any other metadata that describes the media to be sent.
3. Answer: The offer is sent to the remote peer using the signaling server. The remote peer receives the offer and creates an answer which it sends back to the caller.
4. ICE: The RTCPeerConnection uses the ICE (Interactive Connectivity Establishment) framework to find the best path for media to travel between the peers. This includes finding the public IP address of the peer and the port that the media is being sent to.
5. Media: Once the offer and answer are exchanged, the ICE framework has found a path for the media, and the peers have agreed on the codec and media format to use, the media begins to flow between the peers.

WARNING: This project is still under development and hosted for free on Cloudflare Pages and Render. The free tier has limits. If the limit is reached, the website will be temporarily disabled. If you encounter any issues, please try again later. The website may be slow to load due to the free tier limitations and has 50 seconds of startup time if inactive (a.k.a no calls to backend).
