I would point at that time delay being more related to various aspects
of my bête noir, bufferbloat, cropping up, be it in the transport
itself, or in the application. RTMP implementations, in particular,
are notoriously laggy. There are multiple other problems possibly in
that time delay related to encode, decode time. Also, for all we know,
some of that lag was for a censor on the stream.

Actually investigating where those 15 seconds went would be
interesting - who to ask?

Recently some congestion controlled webrtc optimizations for OBS and
twitch arrived from this fella:

I really don't think that "multicast" could have helped until we
started to get rid of the other 14.9 sec built into the system here.
