Clapper is a modern media player designed for simplicity and ease of use. Powered by GStreamer and built for the GNOME desktop environment using GTK4 toolkit, it has a clean and stylish interface that lets you focus on enjoying your favorite videos.
Clapper uses a playback queue where you can add multiple media files. Think of it like a playlist that you can build. You can easily reorder items or remove them from the queue with a simple drag and drop operation.
