![]() Produced file cannot be reproduced and fails to be loaded on TS Analyzer Using TShark command tshark -r -Y "udp.stream eq " -w, produced output file in secondsįile size is slightly bigger than tcpdump capture, like 200kB Using Wireshark GUI, follow UDP stream (ASCII), packet read/parse took 3 minutesĬhanged from display and save from ASCII to RAW, packt read/parse took less than 1 minutesįile can be reproduced on VLC and is succefull loaded on TS analyzer At least is not needed to perform the same twice, but it produced the same output as the previous command, also not possible to use on stream analyzer neither VLC. ![]() Console window started to show up the bunch of raw data, taking similar time that Gui does. That process is completed in some seconds for the same file that takes one but it produced an output file slightly bigger than the original tcpdump captures what is not expected and is not recognized as TS files by the softwares i have, while the file produced by the long follow the stream process are.Īlso tried the -z follow,UDP,0 instead of -Y udp.stream eq. ![]() The proposed solution is: tshark -r -Y "udp.stream eq " -w Since the goal is save the raw udp payload, change from default ascII to raw is needed and once performed, the packet count stats over, needed the same long time to end to finally complete the process After quite some time, when the packet count ends, the option are available to use. A new popup windows opens and packet count starts while not button or fields are enabled to use, including the mode that is default ASCII. You can also do this with editcap: editcap -F k12text a.pcap a.The goal: Extract TS Files captured from UDP streams (multicast)Ĭurrent mode: Choose follow -> UDP stream using Wireshark GUI. So, if you want to read the pcap file and write it out as a "K12 text format" file, you can do it with tshark -F k12text -r a.pcap -w a.txt However, from a user-interface sense, it's more like "Save As." in Wireshark, because it's a capture file format. "K12 text format" is a text packet capture format it's what some Tektronix equipment can write out - in that sense, it's similar to writing out the raw hex data, plus some metadata. So there's no such thing as "the" text format to save a pcap file as there are a bunch of choices. a C source file showing the raw hex data of the packets, with each packet being in a separate C array of byte values.a JSON file showing the details of each packet.a PDML file showing, as XML, the components of the details of each packet.a PSML file showing, as XML, the components of the packet summaries.a CSV file of particular fields from the packet.a CSV file of columns from the packet summaries.a combination of two of those, or of all three of those.a file showing hex dumps of the packet data (showing, for each packet, the default bottommost pane of Wireshark).a file showing the packet details of each packet as text (showing, for each packet, the default middle pane of Wireshark). ![]()
