[Live-devel] Creating a RTSP stream from DVB-T hardware card

Does the unchanged "testMPEG3TransportStreamer" demo application work 
correctly when you stream a Transport Stream *file* that you 
previously recorded from your capture device?  It should, but if - 
for some reason - it doesn't, then do not proceed to step 2 :-)

No, the "MPEG2TransportStreamFramer" also has the job of (1) 
accumulates the incoming Transport Stream packets into groups of 7, 
so that they end up getting packed into outgoing RTP packets 
efficiently, and (2) computing the presentation time and duration of 
each Transport Packet, so that the outgoing RTP packets get 
transmitted with appropriate spacing between them.  You should 
continue to use the MPEG2TransportStreamFramer" object.
