Re: OT: RTP Stream Analysis and Reporting

Hey Joshua,

Pilot is actually where I started but I don't see where it does
anything with RTP (just treats it as UDP) - am I missing something?
My goal is to take static .cap trace files (lots of them - and big!)
that have already been captured and analyze them for missing or
undordered RTP sequence numbers (etc). And then ideally provide one
report or graph or chart to my client that says "during n number of
hours of capture, you had x lost datagrams and y unordered
datagrams." Or, failing that, one report per trace file. I can do
this with Wireshark but it's very time consuming and the RTP analysis
popup window doesn't have a print or print to PDF function. It has a
graphing capability but that's limited to jitter - I need to export
sequence number analysis data.

Thanks much,

Scott
