I am trying to building proctoring system using mediasoup in which i will build one viewer to many broadcasters how i can customize it for that?
You don’t customize mediasoup. You read the api documentation and build your custom app using it.
ibc said the right thing, @vaibhavpnimkar first you need to understand how producers, consumers work and then you can use that process as per your own need. Whether that is conference call or live streaming or proctoring system. You can use mediasoup demo as your base and then go forward from there.
