The problem is your input data: It's apparently malformed (at least, when 
it gets to the "MPEG2TransportStreamFramer" code).

The "Missing sync byte" error message (in 
"MPEG2TransportStreamFramer::updateTSPacketDurationEstimate()") occurs when 
the data that you've just read does not contain a proper Transport Stream 
sync byte (0x47) at position 188, or 188*2, or 188*3 etc.  (At this point 
the code has already checked that the first byte (at position 0) is a sync 
byte.)

You can verify this by adding code to "MPEG2TransportStreamFramer.cpp" at 
line 95 - i.e., just after the line
         } // else normal case: the data begins with a sync byte
that prints out the data (from "fTo[0]" through "fTo[fFrameSize-1]", 
inclusive).  If you do this, you'll see that your input data is bad.
