[Live-devel] frame headers

Hi Ross,

Question about multi-frame packetizing due to having trouble keeping 
track of buffer sizes.

Where is the best place to process frame-specific headers that must be 
placed before each frame in a packet when there will be multiple 
frames? While RTPSink's doSpecialFrameHandling gets called for every 
frame, the setSpecialHeaderBytes puts all the data after the RTP 

My haunch is in a FrameSource's doGetNextFrame(), however I'm a bit 
confused as to what values fPrefferedFrameSize/fMaxSize and fTo 
correspond to; until now I have been assuming strictly raw data with no 
such headers, so I'm concerned with buffer-overflows...
