Yaniko Video Downloader is distributed with the open source components listed below. Each remains under its own licence, and nothing on this page limits the rights those licences grant you.
The app bundles an FFmpeg 7.1 executable
(ffmpeg.org), used to combine the separate video
and audio streams that video sites deliver. The build we ship is configured with
--enable-gpl and is therefore licensed under the
GNU General Public License,
version 2 or later.
The complete text of that licence is reproduced verbatim at getyaniko.com/gpl-2.0.txt, and is also published by the Free Software Foundation at gnu.org.
FFmpeg is shipped unmodified, as a standalone executable that the app runs as a separate process. It is not linked into, or combined with, Yaniko Software's own code.
The corresponding source code for the FFmpeg build we distribute is available from ffmpeg.org (release 7.1). If you would prefer to receive it directly, write to support@getyaniko.com and we will send you a complete machine-readable copy of the source, on request, for three years from the date you obtained your copy of the app. This offer is valid to anyone who receives this software.
The exact binaries we ship are the macOS builds published in the imageio-ffmpeg 0.6.0 distribution, combined into a single universal binary without modification.
The app bundles a quickjs-ng 0.16.1 qjs executable
(github.com/quickjs-ng/quickjs),
used to run the JavaScript that video sites require before they will serve real video
formats. It is shipped unmodified, as a standalone executable that the app runs as a
separate process, and is licensed under the MIT License.
