Our Transport Stream RTP streaming code will transmit exactly the
Transport Stream data that it was given (plus RTP headers, of
course). Therefore, if you are seeing extra PES header data in the
network packets, then this data must have been present in the
Transport Stream data that's being streamed. Therefore this extra
PES header data will (most likely) also be in at least some of the
".ts" files that you list above.
To make it easier for me to track down your problem, could you please
say which of the seven ".ts" files that you list above contain this
extra PES header data?
