Searching for information on DVB-S2 BBframe structure I went into this wiki: http://wiki.wireshark.org/DVB-S2
Wireshark seems to decode this kind of data.
I’m using Wireshark 1.8.2 on ubuntu 12.04 – and everithing seems to be fine.
But I’ve downloaded the capture file and WS cannot recognise the DVB packets in the UDP payload.
I tried to inform it manually by “right click > decode as” in a packet, but there’s no DVB protocol available to select.
It seems then I need to install the dissector informed on the wiki – but where can I get it and how can I install it.
The DVB-S2 dissector has not yet been included in Wireshark releases(not even the development releases), however it should be available in a future release since I can see the dissector code in the trunk. See this question for more.
I’m able to dissect DVB-B2 packets using my local Wireshark build. So if you need this feature right away, I guess the best option for now would be downloading the source and using a local Wireshark build for your purposes.
