Transcritorio — third-party components bundled with distributed binaries.

NOTE (2026-08): this notice applies to the LEGACY standalone releases
(.exe/.dmg/AppImage, v0.1.x), which bundled FFmpeg builds. The current
distribution channel (Python wheel on PyPI installed via uv) bundles no
third-party binaries: FFmpeg comes from the user's package manager
(winget/brew/apt) and Python dependencies come from PyPI under their own
licenses.

The Python source in this repository is licensed under the MIT License (see LICENSE).

Some distributed release artifacts bundle static builds of FFmpeg (ffmpeg + ffprobe),
which are licensed under the GNU General Public License (GPL). The bundled builds
come from the following upstream sources, which also provide the corresponding
source code required by the GPL:

- Windows x86_64:  https://github.com/BtbN/FFmpeg-Builds        (GPL 3.0 shared build)
- macOS arm64:     https://evermeet.cx/ffmpeg/                  (GPL 3.0 static build)
- Linux x86_64:    https://johnvansickle.com/ffmpeg/            (GPL 3.0 static build)

Using, redistributing or modifying the bundled FFmpeg binaries is subject to the
terms of their license. The Python source of Transcritorio (MIT) and the bundled
FFmpeg binaries (GPL) are distributed together as a convenience; this repository
as source does not include, require or derive from FFmpeg's source code.

This product also relies on the following open-source libraries (each under its
own permissive or compatible license; not bundled as binary):
