I need you to build a video live wallpaper app, you don't have to do much but just add video wallpaper fucntionality to an existing static wallpaper app which already has backend and other advance functinality build in.
I don't need you to use android's medaiplayer class as it dooesn't allow cropping or scrolling.
So, you don't need to add the app from scratch but add video wallpaper functionality to it.
