# Licence files

This directory records terms for third-party components and generated test
data. The application itself is licensed under **GPL-3.0-or-later** by
Albrecht Degering; the complete GNU GPL version 3 text is in the repository
root `LICENSE`.

The root licence applies to av-tools-owned code and documentation. It does not
replace or narrow the terms, copyright notices, source-delivery requirements
or patent considerations of bundled third-party components.

- `ffmpeg.wasm-MIT.txt` is the exact MIT text from the inspected ffmpeg.wasm
  `v12.15` source at revision
  `71aa99d37c02a7b4c435275ca9ef50e612f6efa1`; it covers the wrapper/util
  source.
- `GPL-2.0-or-later.txt` reproduces GNU GPL version 2 for GPL-enabled FFmpeg
  and linked GPL components in the reviewed WebAssembly cores. The legal code
  was checked against the standard GPL-2.0 text in the installed Freedesktop
  SDK licence corpus and the SPDX licence-list text.
- `CC0-1.0.txt` applies only to generated bytes under
  `tests/fixtures/generated/`; it is byte-identical to the CC0 legal code in
  the installed Freedesktop SDK licence corpus.
- `native/` preserves the exact licence, notice and patent files from the
  pinned FFmpeg and linked-codec source trees. Their source revisions are
  recorded in `scripts/ffmpeg-source-lock.json`; every file was copied
  byte-for-byte from the corresponding source bundle.

Release packaging also copies the legal files shipped by installed runtime npm
dependencies into `LICENSES/npm/` inside the ZIP. See
`THIRD_PARTY_NOTICES.md` and `SOURCE.md` for versions, provenance and release
source-delivery requirements.
