Flussonic to Flussonic

I am pulling channels on one server via UDP. I want to push those channels to other Flussonic server. Currently, I am using HLS. I can two other options: (I) M4F [Flussonic-toFlussonic protocol (fragment)] and (II) M4F [Flussonic-toFlussonic protocol (stream)].

My question is what should be best to use HLS, M4F or M4S and why?

Use m4f. It is most lightweight for inter-flussonic communication.

m4s should be used only for zero-latency installations like webrtc/rtsp
