How make UI to control record video

Hi.
I’m find tool or API and tutorial to handle record video for android.
It is controlled by UI button: start and stop record.

I found a tool Evereal. This can record in Unity but not work on my android app unity.
Link Evereal : https://evereal.com/tutorials/how-to-capture-video-in-unity-3d

Can you give me solution for this problem?
