A free app for Android, by NAINGDroid

Video Live Wallpaper is an Android app that enables you to set any video as a live wallpaper, including those in your own personal album. This app greatly helps you in editing a portion of the video, scaling it to fit the screen, and turning on or off the audio.

Live wallpapers use the device’s gyroscope to replicate the user’s physical motions. They can be fluid designs that change viewpoint or animated GIFs that play on a loop. The majority of operating systems, including Android, naturally support live wallpapers. By pressing and holding them, you may see them animate on your phone’s lock screen.
