How to hide the real path to a file through Nginx?

Question

Nginx

You need to change the URL through NGINX so that the direct path to the file is not changed, but changed.
site/231ds3f54sdf15/live.mp4
I can write in PHP, but I still want to use Nginx (enter IP + Time(time for one hour) = 231ds3f54sdf15 this is an example)
