Open Source Licenses
AI LED Banner includes the open-source software, fonts, and bundled CC0/Public Domain music listed below. Their respective copyright notices and license terms apply. This page covers the iOS release identified above; it excludes development-only tools, Android-only components, and Apple system frameworks.
1. FFmpeg and FFmpegKit
Video/GIF export uses FFmpegKit and FFmpeg locally on the device. The included min build is
LGPL-3.0-or-later; it is not a GPL variant. The following notices and source links are provided for this
release.
| Component | Version / use | License and source |
|---|---|---|
| ffmpeg_kit_flutter_new_min | 3.6.2 · Flutter bridge for local media export | LGPL-3.0-or-later · source repository |
| FFmpegKit / FFmpeg | 8.1.2 · bundled iOS media frameworks | LGPL-3.0-or-later · FFmpeg 8.1.2 source |
The application invokes these libraries only to add locally selected background music to an exported MP4 and to convert a local capture to GIF. It does not use FFmpegKit to download, upload, or stream media.
The corresponding LGPL v3 text is available at GNU LGPL
v3. The upstream min package documentation states that GPL codecs such as x264, x265,
xvidcore, and vid.stab are not included in this variant.

For each bundled track, the release record retains its delivered path, original title, FreePD download URL, source category, CC0/Public Domain license, and delivered duration. Maintain this record with the release materials so any automated copyright claim can be investigated.

For FFmpegKit and FFmpeg, the source links in section 1 identify the upstream sources for the versions used by this release. Before distributing any release that bundles the iOS FFmpeg frameworks, the release process must retain and make available the exact corresponding source, build configuration, patches, and replacement/relinking information required by the applicable LGPL terms. This requirement also applies when the FFmpeg version or configuration changes.
7. Keeping this notice current
This inventory was generated from the iOS Podfile.lock, Flutter dependency resolution, and bundled
font-license assets, and the background-music release record for version 1.0.0 (24). It must be regenerated
whenever a dependency, font, FFmpeg build, music asset, or app version changes.
