Design and Implementation of a WASM Demuxer for WebCodecs Video Frame Extraction
The project extracts FFmpeg’s demuxing logic into a lightweight WebAssembly module that feeds container‑agnostic video packets to WebCodecs, enabling fast, low‑cost frame extraction across many formats and cutting cover‑generation latency by ~40% while reducing container‑related failures by ~72%.
