I've briefly looked at packet-dvb-s2-bb.c ,and it seems it does BBFrame
ans well as some GSE handling. Before adding GSE reassembly, I think I
might try to factor the GSE stuff out into a new packet-dvb-gse.c. Two
reasons: an S2 BBFrame may contain MPEG2-TS or GSE, and GSE may be
transported over DVB-T2 and DVB-C2 as well. I doesn't seem dissecting
MPEG2-TS in S2 BBFrames is supported today?


That's correct. The original authors were apparently only interested in
dissecting GSE, and that was consistent with my use cases, so I left it
that way.

I don't know much about MPEG2-TS. I assume you'd mostly want to dissect the
logical channels that carry IP packets. I'm guessing there isn't much
utility in a detailed dissection of audio or video channels.

I think factoring GSE out makes sense if you can cleanly invoke it from the
DVB-T2 and/or DVB-C2 dissectors. I haven't looked at that, though DVB-T2 is
also of interest for my ham radio project. Do those dissectors even exist
yet?
