The rest of the docs imply this information as well, so I now need to
change the whole setup I was working on. Kinda frustrating, but such
A bigger question is, then: What is the whole point of RTP? If you are
multicasting to multiple receivers without resampling, then there is
a bufferring problem which will guarantee drop-outs or gaps.
I.e. it seems to me the effective use of RTP for audio is broken.
Is this in the plans to be fixed? (or am I basically volunteering... ;-)
FWIW, I noticed the other thread "Controlling where module-rtp-send
sends multicast packets?" which is talking about the use of
module-combine and tunnelling, but I have a many-to-many situation
and without a central "owner" of audio it seems a bit weird to do it
the other way.
