Open-source software in CreekX

CreekX's installer puts these programs on your server beside CreekX. Each keeps its own licence, which governs that program; CreekX runs them as separate programs and links none of them into its own code. The JavaScript libraries built into CreekX itself are listed with their licences in app/*.LEGAL.txt in every release.

Program	What it does in CreekX	Licence
FFmpeg 8.1 (ffmpeg, ffprobe)	Conversion, recording, pictures	GNU GPL version 3 or later
MediaMTX	The live server	MIT
PostgreSQL 16	Database	PostgreSQL Licence
Caddy	Web server and certificates	Apache 2.0
coturn	WebRTC relay	BSD 3-Clause
Node.js 24	CreekX's runtime	MIT (and the licences of what it bundles)
Ubuntu 24.04 packages	The operating system on marketplace images	Each package's own licence

FFmpeg: licence and source code

CreekX installs a static build of FFmpeg 8.1 for 64-bit Linux, from the BtbN/FFmpeg-Builds project (the Linux builds linked from ffmpeg.org). It is configured with --enable-gpl --enable-version3, so it is licensed under the GNU General Public License, version 3 or later. It contains no non-free components.

Licence text: /opt/creekx/ffmpeg/LICENSE.txt on your server, and https://www.gnu.org/licenses/gpl-3.0.html.
Which build: FFMPEG_VERSION, FFMPEG_URL and FFMPEG_SHA256 in versions.env of the CreekX release that installed it. The part of the version after the last g is the FFmpeg commit (for example, n8.1.3-9-g29e619e767 is commit 29e619e767).
Source code: the FFmpeg source of that commit, at https://git.ffmpeg.org/ffmpeg.git (mirror: https://github.com/FFmpeg/FFmpeg), and the build scripts with every library's source and version, at https://github.com/BtbN/FFmpeg-Builds at the release tag in FFMPEG_URL.

Written offer. For at least three years after we last distribute a given CreekX release, we will give anyone who asks a copy of the complete corresponding source code of the FFmpeg build it includes, on a medium customarily used for software interchange, for no more than our cost of providing it. Write to [email protected], naming the CreekX release.

If the FFmpeg build cannot be downloaded during installation, the installer uses Ubuntu's own ffmpeg package instead (GPL 2 or later); its notices and source are available from Ubuntu as for any Ubuntu package (/usr/share/doc/ffmpeg/copyright).
