Open-Source Notices

Draft pending legal review, alongside the rest of these documents. The substance below — versions, licenses and source locations — was verified against the shipped binaries.

The SeeTheBug Client includes open-source software. This page lists it, the license each component is under, and where to obtain its source code. The same notice ships as THIRD-PARTY-NOTICES.txt next to the installed application, together with the full license texts.

Nothing on this page limits the rights those licenses grant you. Where a license below gives you rights that conflict with our Terms of Service, that license prevails for the component it covers.

FFmpeg

This software uses libraries from the FFmpeg project under the LGPL version 3.

FFmpeg ships as separate ffmpeg and ffprobe executables in the resources/ffmpeg folder of the installation. The Client runs them as separate processes and does not link against the FFmpeg libraries, so you are free to replace those executables with a build of your own.

The build we distribute was produced without --enable-gpl and without --enable-nonfree, and with --enable-version3 — which is why it is covered by version 3 of the LGPL rather than version 2.1. Running ffmpeg -version will show you the same configuration.

The binary was obtained from the BtbN FFmpeg-Builds project.

Corresponding source: FFmpeg at git revision 743df5ded9. If that location is unavailable to you, use the written offer below and we will send it to you directly.

libuiohook

libuiohook provides global keyboard and mouse hooks. The Client uses it in two places:

• Keyboard hooks in the on-screen keystroke display, which shows the keys being pressed while a reproduction is recorded.
• Mouse hooks in the main application’s screen recorder, to detect clicks, double-clicks, right-clicks and drags so they can be drawn as indicators over the recording. Windows and macOS only, and only while a screen recording is in progress.

It is compiled into the native module uiohook-napi, which is installed as an ordinary file rather than inside the application archive.

We have modified libuiohook. The change adds the typed character or characters to the EVENT_KEY_PRESSED event on Windows, and touches src/windows/input_helper.c and src/windows/input_hook.c.

Corresponding source: the complete source of our modified version, from which the shipped module can be rebuilt, is published at github.com/sdaliyot/libuiohook — branch 1.2, commit 12d5ee8b5e7e8eb4e3a6070aa2d05161486524fb. Because the compiled module is installed as a plain file, you can rebuild it from that source — with or without your own changes — and replace the installed copy.

Electron, Chromium and Node.js

The Client is built on Electron, which bundles Chromium and Node.js. Their licenses, and those of their own third-party components, are installed with the application as LICENSE.electron.txt and LICENSES.chromium.html.

Other components

The Client also includes open-source JavaScript libraries under permissive licenses — principally MIT, ISC, Apache-2.0 and BSD variants — each of which permits redistribution in binary form with attribution. A full list with license texts is available on request from the address below.

Written offer for source code

For three years from the date you received the software, SeeTheBug will give any person who possesses it a complete machine-readable copy of the corresponding source code for the LGPL-licensed components above — FFmpeg and libuiohook.

To request it, write to support@seethebug.com, stating which component you want and the version of the Client you have installed. We will supply it by download or on a medium customarily used for software interchange, at no charge beyond any reasonable cost of physically performing the distribution.
