GStreamer

GStreamer, a third-party dependency used in Whack for the video player, is distributed under LGPL 2.1 (GNU LESSER GENERAL PUBLIC LICENSE).

Creators must ensure that, when distributing Whack in a binary, they:

• Give a notice that they indirectly use GStreamer
• Link to the GStreamer source code
• Provide the GStreamer license file (LGPL)

GStreamer source code can be accessed at:

• gitlab.freedesktop.org/gstreamer/gstreamer
• github.com/GStreamer/gstreamer

Their LGPL license obligates allowing users to replace the GStreamer library. In that case, the Whack packaging tool outputs GStreamer as a shared object somewhere in the app package, which users can identify and replace the file by another one.
