Clapper – GNOME media player built using GJS with GTK4 toolkit


Clapper is an exciting development. We love that it reduces the space required by the playback controls to the absolute minimum. Combine that with a borderless window without a header, and this media player is immediately appealing. The floating mode is sublime.

Hardware acceleration works well. On Intel systems, you can verify hardware video acceleration is enabled with the command.

$ sudo intel_gpu_top

Here’s the output we see when playing a video.

Clapper - hardware acceleration

The Video Engine is greater than 0% indicating that hardware video acceleration is in operation. Hardware acceleration reduces CPU and RAM usage.

Memory usage is reasonable. Playing 3840×2160 H.264 video, the software consumes around 280MB of RAM. That’s slightly higher than the development release of VLC 4.

The software is in an early stage of development so it’s lacking a lot of functionality offered by our recommended free and open source media players. And there’s a fair share of bugs along the way. But Clapper might already meet your feature requirements.

  1. I’ve got so accustomed to Firefox’s picture in picture feature that I started to dislike window decorations on video playback.

    Clapper’s floating mode is brilliant. Overall the video player is pretty basic when it comes to functionality but from brief experiments it’ll definitely stay on my system. I haven’t yet tried using it as an audio player.

  2. Forgot to mention that it only runs under Linux, the developer doesn’t intend to port the software to Windows or macOS which is a shame. I run all 3 operating systems and prefer to use the same software on each environment.

  3. Was the RAM usage tested on X11 or Wayland? I ask cause Clapper seems to perform better and uses less resources on Wayland session.
