need help in android app

Hi,

I hired a few developers to make me an app, where it does the following:

Select any video from your gallery and convert it into 4 sides. Same video playing, but playing in all 4 sides, left right, up, down. Please see pictures attached. then it must play full screen. that's all!

Is there an extension that can be used? they all say its not possible for android but it is for IOS. can someone help me here so i can guide all this developers.

Thanks again
