Reference Tables

Software	License	Source Code	Notes
FFmpeg	GPLv2+	Source	Core video processing code (ffmpeg.org).<br/>``<br/>FFmpeg is available under two licenses: the GPL and the LGPL. Remotion distributes a compiled FFmpeg binary under the GPLv2+ license; the source and build scripts are publicly available.<br/>``<br/>Because x264 and x265 are licensed under the GPL (not the LGPL), Remotion's FFmpeg binary cannot be distributed under the LGPL. The bundled AAC support uses fdk-aac-free, which has no licensing concerns. No other components in Remotion's FFmpeg binary should raise licensing concerns.
Chromium	BSD 3-Clause	Source	Browser engine used for rendering videos (chromium.org)
Mediabunny	MPLv2.0	Source	Media processing library (mediabunny.dev)
Webpack	MIT	Source	JavaScript module bundler (webpack.js.org)
