Third-party licences
Clam Sync includes the following open-source software, each under its own licence. The full licence texts are inside the app: Help → Open-Source Licences.
| Component | Licence | Source |
|---|---|---|
| FFmpeg (Mac: built from source; Windows: BtbN's LGPL build) | LGPL 2.1 or later | ffmpeg.org, BtbN/FFmpeg-Builds |
| Qt and PySide6 / Shiboken6 | LGPL 3 | download.qt.io |
| Python | Python Software Foundation License | python.org |
| NumPy | BSD 3-Clause (plus bundled libraries' licences) | github.com/numpy/numpy |
| SciPy | BSD 3-Clause (plus bundled libraries' licences) | github.com/scipy/scipy |
| pyaaf2 | MIT | github.com/markreidvfx/pyaaf2 |
FFmpeg and Qt are separate files inside the app, so they can be replaced with other builds, as the LGPL requires. Our licence agreement lets you do this, and reverse-engineer the app as far as needed to debug such a replacement.
FFmpeg is a trademark of Fabrice Bellard. Qt is a trademark of The Qt Company Ltd. Clam Sync isn't affiliated with or endorsed by either.
