The Project
FaceCam 2.0 is a production-grade real-time broadcasting system purpose-built for esports. We architected a MediaSoup SFU where each tournament owns a dedicated router and CPU core, with simulcast encoding so consumers only pull the resolution they need — 240p for grid monitors, 480p for broadcast output. Four role tiers (Owner, Admin, Marshal, Player) each get a tailored dashboard. The vMix and OBS browser sources use a pause/resume consumer model: all 64 streams connect at startup but stream zero bandwidth until the director explicitly activates a player, enabling instantaneous switching with no black screen or buffering. A React Native mobile app with sender-side congestion control mirrors the browser broadcaster on iOS and Android.
01 — Architecture
Designed MediaSoup SFU with per-tournament routing, simulcast encoding pipeline, and selective consume to keep bandwidth predictable at scale (344–440 Mbps peak on a 1 Gbps port).
02 — Build
Implemented real-time WebRTC infrastructure, role-based dashboards, vMix/OBS browser sources with pause/resume switching, and a React Native mobile app with sender-side congestion control.
