#javascript Audio/Video Streaming: #WebRTC APIs 101 explained

on YouTube ↗26m

" summary

A minimal video‑call app is built from scratch and demonstrably works across Chrome and Firefox using browser APIs and a tiny Node.js server: it captures camera/mic with getUserMedia, creates peer links with RTCPeerConnection (SDP offers/answers, ICE candidates, STUN for public IP, TURN as fallback), and exchanges signaling over a simple WebSocket signaling implementation over HTTPS. The demo runs live, STUN handles ~80–90% of cases, TURN relays when needed.
