Legal & Attributions

OpenMuse is built on the work of many open-source projects. This page lists the licenses and attributions for components bundled with the desktop app.

OpenMuse License

OpenMuse is proprietary software. That includes the desktop app and hosted services. The OpenMuse license ships with every desktop release as LICENSE.

Third-party components bundled with the app retain their own licenses; they are listed below and in THIRD-PARTY-NOTICES.txt.

Privacy & Analytics

We use PostHog (EU-hosted) for anonymous, cookieless analytics on this website. We do not set cookies, do not use localStorage for tracking, and do not track you across sessions or devices. IP addresses are discarded at ingestion. We capture only aggregate pageviews and a small number of product events (such as download clicks) to understand which pages are useful. We honor the Do Not Track browser signal.

FFmpeg — GPL v3.0 Notice and Source Availability

OpenMuse bundles unmodified FFmpeg binaries (ffmpeg and ffprobe) in the ffmpeg/ subdirectory of the installation. FFmpeg is primarily LGPL-2.1-or-later, but every build selected for OpenMuse Desktop enables GPL and version 3 and is distributed under the GNU General Public License, version 3 . OpenMuse invokes these standalone executables and does not link against FFmpeg libraries. The full license text ships as licenses/FFmpeg-GPL-3.0.txt.

The exact FFmpeg version shipped with any OpenMuse release corresponds to the version reported by ffmpeg -version in that release’s ffmpeg/ directory. The Apple Silicon package runs the documented Intel binaries through Rosetta.

Corresponding source availability

The exact binary downloads, Linux image, and Linux build recipe are listed above. The matching FFmpeg 9.0.1 and 9.0 source revisions are available online. Anyone who receives OpenMuse Desktop may request the corresponding FFmpeg source and available build material from contact@open-muse.com. OpenMuse will provide it at no charge through a network download, or for no more than reasonable physical distribution cost. This offer remains valid for at least three years from the date the corresponding binary was received.

Replacing the bundled FFmpeg

You may replace the bundled FFmpeg binaries with your own compatible build. Replace the files in the ffmpeg/ subdirectory of your OpenMuse installation with your own ffmpeg and ffprobe executables. OpenMuse will invoke them directly.
