Re: OT: RTP Stream Analysis and Reporting

Hi Scott,

I would suggest that you need to see if you can obtain this data via the
built in scripting capability using Lua -
http://www.wireshark.org/docs/wsug_html_chunked/wsluarm.html I have to warn
you that there isn't a great deal of tutorial data available but it may be
handy. Alternatively in the past I have had to do a two step process with
exporting the packet dump from wireshark to a plain text file and then
parsing it with a script to pull the relevant data of interest together to
create a report. This can be helpful if you want to do a packet analysis
but don't want to have to do reassembly yourself.

Cheers,
Adam
