I have just installed a new version (2021.02.05) of the “LIVE555 Streaming 
Media” software that changes (improves) the mechanism by which we figure out 
our IP address.

Previously, we used a 'multicast loopback’ mechanism (sending a packet to a 
multicast address, receiving it, and noting the source address of the received 
packet).  Now, instead, we use the "getifaddrs()” function to get our IP 
address(es).

If "getifaddrs()" doesn't work, then we use the same 'fallback’ mechanism as 
before: "lookup host name” ->  resolve host name”

Should this not work for you - or if "getifaddrs()" is not defined on your 
system - then please let me know.  (If you wish, you can disable the 
“getifaddrs()” mechanism by compiling with NO_GETIFADDRS defined; if you do 
this, the code will use the fallback mechanism only.)
