Celluloid (formerly GNOME MPV) is a simple GTK+ frontend for mpv. It aims to be easy to use while maintaining high level of configurability.

Iimbonakalo:

Configuration files: Celluloid is capable of using mpv’s configuration files as-is. Keybindings can be set up using mpv’s input configuration file.

Drag and drop playlist: The playlist entries can be added, removed, or rearranged easily with drag and drop operations.

MPRIS2 support: Celluloid implements the MPRIS D-Bus Interface. This allows for better integration with desktop environments that have compatible MPRIS clients.

Wayland support: Celluloid is fully functional on Wayland.
