Demystifying WebRTC

on YouTube ↗21m

" summary

Explains how WebRTC composes standards (SDP, DTLS, STUN/TURN/ICE) to negotiate encrypted, realtime connections, and how ICE probes candidate pairs to pick the working route. Describes media over RTP/RTCP with codecs like Opus, why interframe vs intraframe matters, and client‑server topologies (SFU/MCU) used in production. Gives a working example app that streams webcam video between peers, notes Twilio TURN use and that ~98% of clients avoid heavy relaying.
