Hi Robert, Thanks for the post as well.
Yeah, we actually tried that as well. Had the streams being deleted/stopped/with while loop. Still hang-ups occurred. >From all the insight that I can see, if you just use the create/delete once in a app it will prevent lockup, because of os bug with heap allocations. So, we need to find a way to make the callback work more than once on a recording stream. If that is solved, the work around is not to bad, dependant on what you are doing in your applications. If you have time, try to implement just the create and delete once, use the start/stop and see what happens. I would like to have you confirm this bug as well "Callback executed only once on input stream".
