I'm working with a capture file in which a particular conversation suffers from a periodic interruption. I'd like to be able to use that delay in a display filter, but it just doesn't seem to work when I'm dealing with one conversation among many. I've tried:
tcp.stream eq 12 && frame.time_delta_displayed > 5.0
tcp.stream eq 12 && frame.time_delta_displayed == 6.671905000 (from Copy -> as Filter in Details)
but both yield empty results. Now, I can save that conversation to a separate file and then use:
frame.time_delta > 5.0
so my immediate need has been met. Is there any other filter that would select such packets WITHOUT the need to isolate the conversation in a separate file?

Yes, you can enable TCP conversation timestamps (go to the TCP protocol preferences) and then use:
(no need to select one particular TCP stream, unless you are interested in one particular stream of course).
