web presenter 4K and srt

can a web presenter be a listener and transmit video?
how can this be done...

the server must always be in the form srt://server-name:port ??

Yes.

There are other post in here that kinda cover the various methods of using SRT. I feel if your going for what you asked then its straight up. If there is a passcode, there is a flag for it. I can not remember it but you can find it some where in this forum.
