I've been working with protocols encapsulated into MPEG2-TS but I can't save the raw stream straight into a pcap file. Those protocols include DOCSIS (cable modem) and DSM-CC (IP packets into DVB streams). Unless I'm mistaken, there is currently no DLT_ value for MPEG2-TS.
So that's "MPEG-2 Transport Stream" as in H.222.0 (which, unfortunately, is also an ISO standard, so you have to pay money for it...)? If so, would each packet in the file be a "transport packet", in the form as shown in Table 2-2 of section 2.4.3.2 "Transport Stream packet layer" of H.222.0 (2006-05)? If so, is the sync byte the first byte, or is the 16-bit field containing the transport_error_indicator, payload_unit_start_indicator, transport_priority, and PID at the beginning of the packet in the file? (Presumably in big-endian order, as "uimsbf" means "unsigned integer, most-significant bit first".)- This is the tcpdump-workers list. Visit https://cod.sandelman.ca/ to unsubscribe.
