FFmpeg in Secretly for desktop (macOS and Windows)
==================================================

Secretly uses FFmpeg (https://ffmpeg.org) to process video: trimming, video
messages, compression and animated avatars. It comes from FFmpegKit, through
the Flutter package ffmpeg_kit_flutter_new 4.2.1, in the "full-gpl" variant.

Licence
-------
The FFmpeg shipped with this application was configured with --enable-gpl and
--enable-version3 and includes GPL-licensed libraries, among them x264, Xvid
and vid.stab. As shipped, FFmpeg and FFmpegKit are therefore licensed under
the GNU General Public License, version 3 or (at your option) any later
version. The full text of the GPL version 3 is in FFmpeg-COPYING.GPLv3.txt,
next to this notice.

The package ffmpeg_kit_flutter_new also carries the GNU Lesser General Public
License version 3 as its default licence file, and the list of licences in the
app shows that text under the package's name. It describes the LGPL variants
of FFmpegKit, not the build shipped here.
