RTC @Scale, Resilience and Encryption Session | Live Q&A
summary
Audience Q&A covers concrete tradeoffs: out‑of‑band FEC adds latency so duplication is used for audio while RS code looks promising for video error recovery; video benefits from splitting frames into packets. Perceptual latency benchmarks cited as 300 milliseconds (unnoticeable) and 600 milliseconds (marginal). End‑to‑end identity uses client‑side keypairs and server stores only public keys; verification via scan the QR or security notifications; MLS key exchange is under consideration and leaf‑rekeying uses a guarded window to avoid decrypt gaps.
