FFmpeg and the GPL

To read AVI and WMV videos we serve FFmpeg's WebAssembly build (ffmpeg.wasm 0.12.10), unmodified. It is licensed under the GNU General Public License, version 2 or later (GPL-2.0-or-later). The complete source code of the build, with its build scripts, is at ffmpeg.wasm 0.12.10, and FFmpeg's own source is at ffmpeg.org. You can also ask us for a copy of this source code: write to [email protected]. This offer is valid for three years.
