This will work only if the 'read()' function returns only a complete 
NAL unit - nothing more and nothing less.

Also, you should really be doing the read asynchronously - e.g., 
using TaskScheduler::turnOnBackgroundReadProcessing()".  Otherwise 
your application won't be able to do any work while your 'read()' 
function is blocked waiting for data.

An 'access unit' is a complete video frame (which is typically made 
up from several consecutive NAL units).  Your 
"currentNALUnitEndsAccessUnit()" function returns True iff the NAL 
unit that you're currently delivering is the last NAL unit in an 
access unit (video frame).
