CrystalPlayer
A web-based live streaming player built on the open-source libmedia project. I work on protocol support, WebCodecs / WASM decode paths, SEI timecode parsing, adaptive bitrate switching, and observability.
SEI · 00:00:00:00 — FULL STACK / VIDEO ENGINEER
Hello
Full-stack engineer working on streaming players, real-time protocols, and observability. Currently building CrystalPlayer at IKG Studio, a web live player based on libmedia.
PIPELINE — three practical layers behind a frame
-
01
INGEST
Streaming protocols
RTMP, HTTP-FLV, WHEP / WebRTC, from low-latency playback paths to multi-CDN failover.
-
02
DECODE
Decode pipelines
WebCodecs hardware decode and WASM software decode paths, with SEI timecode parsing and adaptive bitrate switching.
-
03
OBSERVE
Observability
Prometheus / Grafana monitoring, plus an EventBus boundary between player behavior and metrics reporting.
REEL — work & projects
Limit Order Book Visualizer
A market-structure side project that visualizes limit order book dynamics in real time, with a longer-term path toward a C++ matching engine compiled to WASM.
AIMT — internal validation tool
As a Network Validation Engineer, I built an internal React, Express.js, and PostgreSQL tool to make validation work easier to trace and repeat.
ABOUT
I am based in Taiwan and work around streaming media, browser video, and systems engineering. I also keep a long-running interest in GPU / ML systems, electronics projects, and small tools that turn fuzzy ideas into working things.
