WebRTC: Let’s Revolutionize Information Sharing in the Browser
summary
WebRTC enables real-time audio, video and arbitrary data directly in browsers using APIs like getUserMedia, RTCPeerConnection and RTCDataChannel. The talk covers the full-stack approach: HTTPS and WSS for signaling, ICE with STUN/TURN relays, SRTP encryption for media, and helper tools like adapter.js plus libraries such as simplewebrtc and PeerJS. Demos include screen sharing, canvas mixing of multiple streams and a pong game over the data channel (with a remote-control demo that failed in one run).
