Need a Ovelay hide Screen recorder with customized rom

Hi Guys, Hope you are doing good, I play pubg a lot and a idea came to me, I am using some external hacks which displayed over the pubg, so i need you guys to hide those overlay icon and the lines and boxes which are caused by esp, There are actually two ways for this one is with customising the rom with inbuild screens recorder only records android UI another one is little bit difficult which is creating a apk which hide overlay and capture only the game,

For your clearity i have attached some youtube videos please look into and bid if you are confident enough to finish the project.
