WebRTC in Chromium: Simplified Explanation

WebRTC: Bridging Users Directly, Navigating the Internet’s Challenges with Ease

WebRTC (Web Real-Time Communication) is a technology that enables real-time communication (like video calls, voice calls, and file sharing) directly in the browser without needing plugins or third-party software. Chromium (and browsers like Chrome and Edge) has built-in support for WebRTC. Here’s how it works in Chromium:

Key Components of WebRTC in Chromium

1. MediaStream (getUserMedia):

• Allows access to the user’s camera and microphone to capture audio and video.
• Example: When you grant a website access to your webcam for a video call.

2. RTCPeerConnection:

• Handles the connection between two devices (peers) for real-time communication.
• Manages audio, video, and data transfer.
• Uses ICE (Interactive Connectivity Establishment) to find the best path for data transfer, even through firewalls and NATs (Network Address Translators).

3. RTCDataChannel:

• Enables peer-to-peer transfer of arbitrary data (like text, files, or game data).
• Useful for applications like chat, file sharing, or multiplayer…
