[Live-devel] PES to Transport Stream Framer

When this happens, it's usually because your 'framer' object is not 
able to compute the duration of each Transport Packet (and so, each 
packet gets the default duration of 0).  The reason for this is 
probably that your "MPEG2TransportStreamFramer" is not finding PCRs 
in the Transport Stream data.

This looks good. However, you should first try just converting the 
Program Stream file into a Transport Stream file, e.g., using our 
"testMPEG1or2ProgramToTransportStream" demo application (whose code 
you have adapted).

I.e., first try to generate a Transport Stream file from your Program 
Stream file.  Then, try to stream that file.  That may give you some 
insight into what is going wrong.
