Does Repo support multiple streams ingest part of application "stream" and combining them into a single stream ?

Hello ,
Great repo. Made my life much easier.
I'm building a multi-party streaming solution (up to 6 concurrent streamers ,many viewers)
I have made the required changes in my Django-REST-API for on publish and on-publish callback to allow for upto 6 streamers to hit the rtmp://${AWS_IP}:{PORT}/stream/$name application.

This means
User Alan will have his own stream key to start a live session after hitting the stream app on nginx end, get authorized from Django end and start the session
Similarly, User David will have his own stream key to start a live session after hitting the stream app on nginx end, get authorized from Django end and start the session.

End goal is to to enable to view Alan's and David's stream & others(max 6) just like in a live broadcast session in a single window where viewers can view and comment and the streamers be talking to each other just like in youtube live.

I saw the condition "SINGLE STREAM" and "MAX_MUXING_QUEUE_SIZE" in the entrypoint-cuda.sh script and
Wondered

> Whether the repo supports multiplexing(combining several incoming streams to a single output file ? Or it means something else ?

Thanking you in advance !
