Is there any way to export a set of captured UDP packets as separate files with just the UDP payload?

I've captured some logs of MAVLink running over UDP, now I'd like to somehow export just the UDP payload bytes of each packet, separately, from wireshark to files. Preferably with something like filenames specifying source/origin IP and port. (Although in this particular case everything is on the same IP.)

Having Wireshark spit out individual files per frame is not something it can do (although for a datagram type protocol that wouldn't be strange thing, in order to preserve message boundaries).

One way to do this is to export the data as a text file (e.g., in JSON or PDML) and post process from there.

Maybe tshark can help a little with that, by using -Tfields and -e to export the field, which will contain the colon separated hex values of the UDP payload, e.g.

tshark -r test.pcapng -Tfields -e

You would probably need to convert the ascii hex stuff back to something binary afterwards, but it could do what you need.
