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. Player works natively on both Xorg and Wayland. It also supports VA-API on AMD/Intel GPUs.
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. It also has a "Floating Mode" which displays video only on top of all other windows for a PiP-like viewing experience. Mobile friendly transitions are also supported.
For best stability Wayland session is recommended. Wayland users with AMD/Intel GPUs can try enabling HIGHLY EXPERIMENTAL "vah264dec" plugin inside player preferences for reduced CPU and GPU usage on standard (8-bit) H.264 videos.
