You're on Mute! WebRTC and our Lives on Screen

on YouTube ↗56m

" summary

Covers how browsers actually connect video calls using getUserMedia, RTCPeerConnection and ICE with STUN/TURN relays, and when to swap mesh peer‑to‑peer for an SFU to avoid N‑party upload blowup. Shows media constraints, getDisplayMedia screen share, and using the data channel for whiteboards and file transfer (demoed via WebTorrent over the data channel). Uses the Web Audio API to detect “youre on mute” and visualise mic levels. Cites Twilio Video stats (Chrome ~69% and over 10% mobile combined) and links an RTC diagnostics tool.
