Zoom on Web: getting connected with advanced web technology

on YouTube ↗13m

" summary

Chrome and Zoom are building a browser-based video pipeline that replaces heavy native clients by combining WebAssembly SIMD for CPU-vectorized tasks like real-time background removal, WebTransport for bidirectional unreliable datagrams and cancellable reliable streams (an alternative to WebSockets that still enforces encryption and congestion control), and WebCodecs for direct encoder/decoder access so encoded frames travel up and down the network and are decoded locally, enabling low-latency conferencing and frame-by-frame editing.
