Corentra uses the unmodified ffmpeg.wasm core 0.12.10 and ffmpeg JavaScript wrapper 0.12.15. The core's WebAssembly file is split into two download chunks for delivery; the browser recombines the original bytes before loading. Source files and build instructions are provided by the upstream projects below.
