Open Source Components

Source code and licences for the free software Zaplix redistributes.

Zaplix ships prebuilt copies of mpv/libmpv and FFmpeg. Both are free software under the GNU Lesser General Public License (LGPL), and neither is built with any GPL-licensed component.

Every one of these is a dynamically linked shared library — or, for the thumbnail tool, a separate executable — so you are free to replace it with your own build. The complete corresponding source for the exact versions we ship is linked below.

1. mpv / libmpv — player core

Zaplix decodes and plays all media through libmpv, which embeds FFmpeg. The shipped binaries self-report LGPL version 3 or later; the build recipes pass -Dgpl=false to mpv and --disable-gpl to FFmpeg.

Platform	Version shipped	Build recipe & source
Windows	libmpv `v0.36.0-403-g652a1dd907`	libmpv-win32-video-build @ 2023-09-24
Android	libmpv (release v1.1.7)	libmpv-android-video-build @ v1.1.7
iOS	libmpv (release v0.6.0), FFmpeg 6.0	libmpv-darwin-build @ v0.6.0

Upstream projects: mpv · FFmpeg. Licence: LGPL v3 (an addendum to the GPL v3).

2. FFmpeg — LAN thumbnail tool (Windows)

The Windows build places ffmpeg.exe and ffprobe.exe beside the application to extract a poster frame from videos shared over your local network. They run as separate processes and are not linked into Zaplix.

Written offer

For a period of three years from the date you obtained a copy of Zaplix, we will supply, on request, a complete machine-readable copy of the corresponding source code for any LGPL component listed on this page — including the exact build configuration used — for no more than the cost of distribution.

Write to gamingdopamin@gmail.com with the component and version you need.

The same notices, with the full licence texts, are bundled with every copy of Zaplix: Settings → About → Open source licenses. That page also lists the licences of the Dart and Flutter packages the app is built from.
