This not as simple as it was for MPEG-2 or MPEG-4 video (where we 
already have code for parsing and streaming video files).  For H.264, 
there appear to be two main difficulties:
1/ Figuring out when a NAL unit ends an 'access unit' (i.e., a 
complete video frame), and
2/ Figuring out the proper presentation times for each 'access 
unit'.  (The presentation times for each NAL unit within the same 
'access unit' will be the same.)

For 'live' H.264 data that comes from an encoder, this is usually 
straightforward.  However, for pre-recorded data that comes from a 
file, it's less obvious.
