Disney前Fox团队发布的ST2110-40解剖器

SMPTE ST 2110-40 dissector

Dissector for SMPTE ST 2110-40 Ancillary Data

Lua Dissector for ST 2110-40 in Wireshark

Project Lead: Thomas Edwards (thomas.edwards@disney.com)

to use in Wireshark:

1. Ensure your Wireshark works with Lua plugins – "About Wireshark" should say it is compiled with Lua
2. Install this dissector in the proper plugin directory – see "About Wireshark/Folders" to see Personal and Global plugin directories. After putting this dissector in the proper folder, "About Wireshark/Plugins" should list "ST-2110_40.lua"
3. In Wireshark Preferences, under "Protocols", set st_2110_40 as dynamic payload type being used
4. Capture packets of ST 2110_40
5. "Decode As" those UDP packets as RTP
6. You will now see the ST 2110_40 Data dissection of the RTP payload
7. You can extract the Closed Captionning Data with the script parse_CC.sh. The utility tshark has to be installed. The script extracts with tshark the CC Data from a pcap file and concatenates them into an output file:

./parse_CC.sh --in=<PCAP_FILE> --out=<CC_DATA_EXTRACTED_FILE>

or to output in stdout:

./parse_CC.sh --in=<PCAP_FILE> -v
