 ## Requirements
+* **GTK4** >= 3.99.2
+* **GStreamer** >= 1.18 (with GstPlayer lib)
+
 Clapper uses GTK4 along with `GStreamer` bindings from `GI` repository, so if your distro ships them as separate package, they must be installed first.
 Additionally Clapper requires these `GStreamer` elements:
 * [gtk4glsink](https://gstreamer.freedesktop.org/documentation/gtk/gtkglsink.html)
 * [glsinkbin](https://gstreamer.freedesktop.org/documentation/opengl/glsinkbin.html)
 
-**Attention:** `gtk4glsink` is my own port of current GStreamer `gtkglsink` to GTK4. The element is not part of GStreamer yet (pending review). Fedora package is available in my OBS repository. It will be installed along with Clapper if you add my repo to `dnf` package manager. Otherwise you might want to build it yourself from [source code](https://gitlab.freedesktop.org/Rafostar/gst-plugins-good/-/tree/GTK4) of my gstreamer GTK4 branch.

Also please note that the GTK4 plugin is conflicting with the GTK3 version of the same plugin. You cannot install both.
 
 Other required plugins (codecs) depend on video format.
