The State of WebRTC

on YouTube ↗53m

" summary

Claim: browsers now do UDP peer-to-peer media and arbitrary data. Implementation: getUserMedia & RTCPeerConnection plus a short-lived signaling server, ICE with STUN/TURN for NAT traversal, and a DataChannel for unreliable or reliable messages. Working evidence: a live Chrome–Firefox demo succeeds (two tabs connect and stream), mobile builds run behind flags, PeerKit and peer-to-peer CDN demos transfer images, Banana Bread shows multiplayer, and Twilio bridges WebRTC to real phones. Remaining surprises: cross-browser codecs, signaling requirements, and mobile UX/permissions.
