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
