[Freeswitch-users] Jitsi + Freeswitch (and general questions about SFU)

[Colin Morelli]

Anthony,

Thanks for the quick reply.

Could you elaborate more on the need for FS to support a hybrid mux/multi
stream model (for a single conference?) I'd love to understand more about
this so I can wrap my head around the efforts involved. I wonder if there's
a phase 1 that could be reached where you'd be forced to choose between
SFU/MCU modes? Understanding that it might sacrifice compatibility with
clients that can't accept multiple video streams, or the particular codecs
that are used on a stream, I would think this allows FS to *at least* play
the role that Jitsi would play today - and allow for future enhancements.

I think MCU makes a lot of sense for many deployments - and is very
sensible to support. The two concerns I personally have with MCU are a) the
obvious CPU constraints imposed on the hosts, but more concerning is 2) the
UX constraints it imposes on the resulting interfaces. #2 becomes
increasingly relevant as WebRTC/mobile/desktop clients become more and more
prevalent.

Best,
Colin
