Question Cast smartphone screen to any smart TV

Hello and thank you for spending your time reading my forum post.

I was wondering how can i cast my game on my smart TV with the app installed on my android device!

The idea is to have 2-3-4 players connected in the same wifi (LAN). One of the devices will start casting there screen in the smart TV. After a while casting will end and another device will cast in the tv.

Edit: Or if i can display from 1 device different camera view (cameraA on device, cameraB on TV)

Basically i need to learn from somewhere or someone how to start casting etc. (and maybe player part if possible)!
