Open Source Notices

Last updated 1 October 2026

Lumora is built on open source work. These are the components whose licences require that you be told about them.

FFmpeg

Video and audio processing uses FFmpeg, licensed under the GNU Lesser General Public License, version 2.1 or later. This app links an LGPL build of FFmpeg; no GPL-licensed components are included.

FFmpeg is dynamically linked, so it can be replaced with a modified build. The licence text and the corresponding source are at ffmpeg.org, and the Flutter packaging used here is the ffmpeg-kit-flutter-new project.

Real-ESRGAN (General x4v3)

AI Upscale runs the Real-ESRGAN General x4v3 model, published by Qualcomm AI Hub under the BSD 3-Clause licence. The model is downloaded on first use and runs entirely on your device.

TensorFlow Lite

On-device inference uses TensorFlow Lite, licensed under the Apache License 2.0.

Flutter and Dart packages

The app is written in Flutter. The full list of Dart and Flutter package licences is available from the button below.
