WebRTC and Sans IO with Martin Algesten
episode 16 — WebRTC and Sans IO with Martin Algesten.
We sit down with Rust developer Martin Algesten for a deep dive into WebRTC and the Sans IO approach to protocol design. Martin traces the surprising origins of WebRTC, explains why real time media over UDP is both powerful and painfully complex, and walks through how peer to peer connections work under the hood. The conversation then shifts to Sans IO design, why it matters for clean protocol implementations in Rust, and how Martin applies it in his own WebRTC stack, str0m.
