It is also the end user deciding whenever to TEARDOWN the stream. Usually the end-user is not part of the event loop (i.e. on another UI thread).

Nonetheless, you must not call LIVE555 code from this (non-event-loop) thread.  You have no choice here.  LIVE555 code - apart from “triggerEvent()” - must all run within a single-threaded event loop.  If you don’t do this, unpredictable errors may occur, and you will not be supported.

I suggest that, instead, your non-event-loop UI thread call “triggerEvent()” to signal - to the LIVE555 event loop - that it needs to start a stream.  Once again, read

It doesn’t make “this use case” more flexible, because “this use case” is not, and never will be, supported.
