Yes, this should work.  Of course, in the case where “fFrameSize == 0”, you must arrange for this code to be called again later, when a (non-empty) frame becomes available.  In other words, you need to handle an ‘event’ when a new frame becomes available.  Remember that LIVE555-based applications are event-based, using an event loop.

If you haven’t already done so, please read
