FFmpeg compiled to WebAssembly
The in-browser video engine is the ffmpeg.wasm core (package @ffmpeg/core), which compiles FFmpeg together with x264 and other codec libraries. FFmpeg is licensed under the LGPL 2.1+; this build includes GPL components (x264), so the combined binary is distributed under the GPL v2 or later. Complete corresponding source code is available from the ffmpeg.wasm-core repository, ffmpeg.org and code.videolan.org; we will also provide it on request to juanma@deepbluecoding.com.
