Is Producer Consumer 1-to-1

Hi I am trying to understand the producer consumer concept.

A voice call with 5 users
Each user with two transports, producer and consumer (or one transport for producing and consuming?)
Each user is also producing a microphone audio stream to the server

How many consumers does each user need? Does each user need a consumer for each other user in the call (n-1)?
Can I combine producer tracks to use in one consumer?

What is the best practice to achieve this?



Why? Each consumer or producer represents one audio or video track. You can’t combine them without re-encoding (you need MCU for that), mediasoup will just forward them as is (because it is SFU).
