At least for native RTP, you will need to convey the SDP in some way. Using
a file seems totally wrong in the context of the wizard. And RTSP follows
such a different setup model that it probably should not be considered
"RTP" (but a different category of its own). Hence you are stuck with SAP

Well it definitely is not intended for others. Then again, I would argue
the "others" are the victims here. They get their SAP playlist cluttered
with unreachable streams. If you want privacy, you shouldn't be using
unencrypted RTP to begin with.

No. Multicast privacy is achieved through ciphering, not through low TTL.

I am trying to _*SIMPLIFY*_ the wizard.

As already said, file is quite helpless in this context. And RTSP would
should be considered as a different streaming target altogether.
