gSlapper is a wallpaper utility for Wayland desktops that supports both static images and video backgrounds. It offers an alternative to mpvpaper, combining conventional wallpapers and animated media in a single application.
The program uses GStreamer rather than libmpv for media decoding. Its architecture allows a single decoding pipeline to serve multiple displays, sharing decoded frames rather than performing the same work independently for each monitor.
gSlapper supports MP4, MKV and WebM videos, together with JPEG, PNG, WebP and GIF images. Animated GIF playback requires the appropriate GStreamer components. Wallpapers can be assigned independently to different monitors.
The application offers configurable scaling modes, fade transitions between static images and runtime control through a Unix domain socket. This allows playback to be paused or resumed and wallpapers to be changed without restarting the program.
This is free and open source software.
