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
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…
