Third-Party Components & Licenses

Last updated: 2026-09-21 · Contact: support@hoardwick.com

1. Scope

Hoardwick's own code — the installer, the desktop user interface and the local server that drives it — is proprietary and is licensed to you under our Terms of Service / EULA. The application also redistributes three unmodified third-party programs, listed below together with their licenses and the exact versions we ship.

2. Components we redistribute

Component	Version shipped	License	Upstream source
`yt-dlp.exe` (archiving engine)	2026.08.19	The Unlicense (public domain)	github.com/yt-dlp/yt-dlp
`ffmpeg.exe` `ffprobe.exe` (media muxing / merging)	N-126497-g5b614efc7e (build 20260911)	GNU GPL v3 or later this build is configured with `--enable-gpl --enable-version3` and includes GPL-licensed code such as libx264, libx265 and libxvid	ffmpeg.org exact source: commit 5b614efc7e

Python 3 is required to run Hoardwick. It is not bundled or redistributed by us — you install it yourself from python.org, under the PSF License Agreement.

3. About FFmpeg: it is GPL v3, not LGPL

Please read this if you are a distributor, reseller or packager. Many FFmpeg builds are LGPL. The builds Hoardwick ships are GPL v3-or-later builds. If you repackage Hoardwick into your own product, your obligations are those of the GPL v3, not the LGPL — in particular you must pass on the license text and preserve the source-code offer for the FFmpeg binaries.

How the two programs relate:

Hoardwick invokes FFmpeg as a separate program (a child process), passing it command-line arguments. FFmpeg is not linked into, compiled into or combined with Hoardwick's own code. They are separate works distributed together.
We redistribute the FFmpeg binaries unmodified and unsigned, exactly as published upstream.
Under the GPL v3 you are free to run, study, share and modify the FFmpeg components. If you distribute modified versions, those versions must remain under the GPL v3.
The GPL v3 applies only to the FFmpeg components. It does not extend to Hoardwick's own code, and nothing in our EULA restricts any right you have under the GPL v3 in respect of those components.

4. Written offer: corresponding source code

If you would like the complete corresponding source code for the exact FFmpeg build we redistribute (version N-126497-g5b614efc7e-20260911, git commit 5b614efc7e), you can either:

download it directly from the FFmpeg project at github.com/FFmpeg/FFmpeg/tree/5b614efc7e, or
email support@hoardwick.com and we will send you the source, or make it available to you, at no charge, for as long as we distribute this build.
