# Conversion engine notices

The browser wrapper is @ffmpeg/ffmpeg 0.12.15. Its vendored ESM files are in `ffmpeg/`; its MIT notice is [LICENSE-wrapper-MIT.txt](LICENSE-wrapper-MIT.txt).

The core is a locally rebuilt @ffmpeg/core 0.12.10-based engine. The served JavaScript and WebAssembly files exactly match the rebuilt outputs in the separately retained verified bundle. The core package records GPL-2.0-or-later; see [LICENSE-core-GPLv2.txt](LICENSE-core-GPLv2.txt) and individual dependency notices in the bundle.
