summary

This session is a practical tour of WebRTC engineering: an Elixir + Membrane SFU (Jellyfish) that bridges WebRTC, RTSP and HLS, with live demo adding an HLS component, Elixir/Python/TS SDKs and Erlang-style cluster load balancing; mobile work showing React Native WebRTC/SDKs and Flutter plugins plus Android manual-linking pain; a browser Whisper-in‑WASM transcription demo (tiny 50 MB model that runs in Chrome extensions but hits CPU and streaming limits); containerized recording options (Chrome VMs, FFmpeg, GStreamer) and a Lambda rendering pipeline that produced 15 min in ~30s — a customer ran 400k renders; plus Janus bandwidth, per-title encoding (thousands of encodes to tune VP9), WebGPU compositing experiments and a Pion‑in‑Elixir rewrite in progress.
