Clapper - GNOME media player
A GNOME media player built using GJS and powered by GStreamer with OpenGL rendering.
Clapper is a GNOME media player build using GJS with GTK4 toolkit. The media player is using GStreamer as a media backend and renders everything via OpenGL. Both GTK4 and GStreamer plugins share a single global GL context which improves performance greatly.
Player works natively on both Xorg and Wayland. It also supports VA-API on AMD/Intel and NVDEC on Nvidia GPUs when corresponding GStreamer plugins are installed.
The media player has an adaptive GUI. When viewing videos in "Windowed Mode", Clapper will use mostly unmodified GTK widgets to match your OS look nicely. When player enters "Fullscreen Mode" all GUI elements will become darker, bigger and semi-transparent for your viewing comfort. Another viewing mode is a "Floating Mode" where all you see is a PiP like video. Mobile friendly transitions (Pinephone, Librem 5) are also supported.
The media player is fully open source, but improvement of underlying software components requires actual hardware. The hardware accelerated video playback cannot be tested on a VM. The collected money will be spent on all kinds of different hardware which will allow to test the player with different video decoders. Thanks to that I will be able to work on improving and bug fixing both Clapper and GStreamer libraries used by this player and many other applications.
