gSlapper is a Wayland wallpaper utility that plays both videos and static images. Uses GStreamer instead of libmpv, which fixes memory leaks on NVIDIA systems.

# Video wallpaper
gslapper -o "loop" DP-1 /path/to/video.mp4

# Static image wallpaper
gslapper -o "fill" DP-1 /path/to/image.jpg

# All monitors
gslapper -o "loop" '*' /path/to/video.mp4
