 ### WORK IN PROGRESS
 This is still early WIP. Many features are not implemented yet and quite a few are still unstable.

The media player is using GStreamer [GstPlayer API](https://gstreamer.freedesktop.org/documentation/player/gstplayer) as a media backend and renders everything via [OpenGL](https://www.opengl.org). Both [GTK4](https://www.gtk.org) and [GStreamer](https://gstreamer.freedesktop.org) plugins share a single global GL context which improves performance greatly.

 ## Installation from source code
 The requirements and how to build from git source code are described in the [wiki](https://github.com/Rafostar/clapper/wiki#installation-from-source-code).
 
+## Q&A
+**Q:** Does using `GJS` negatively impact video performance?<br>
+**A:** Absolutely not. `GJS` here is used to put together the GUI during startup.
+It has nothing to do with video rendering. All used `GTK4` and `GStreamer` libraries are in C.
+Even the custom video widget that I prepared for this player (based on original `GTK3` implementation) is in C.
