Rather than trying to figure out a workaround to a problem that you don't fully understand, I suggest first trying to understand what the problem actually is, and what's causing it. Saying that you're "stuck in SingleStep()" isn't really meaningful, because - in LIVE555-based applications - *everything* runs within a call to "SingleStep()". And these days, the call to "select()" within the "BasicTaskScheduler" event loop can never block indefinitely, because of the "maxSchedulerGranularity" parameter. And it seems unlikely that "recvfrom()" could be blocking, because the sockets it reads from are all non-blocking. > My live 555 is a few months old Everyone should upgrade to the latest version of the software before posting to the mailing list.
