Hi, Anders,

I had a similar idea on how it should be done.I wanted to save some srtp related data once you processs the packets first time like creating a context which carries the ssrc and keys so that it can relate the packets to keys using the ssrc.But unfortunately wireshark cant differentiate between a rtp packet and srtp packet so it just processes the srtp packet as an rtp packet and changes the visited flag to one.

So cant use that flag which is generally used to differentiate the first iteration from the next ones.So i tried to put my own flag in the pinfo structure and modify it,but that did not work, as it looks like pinfo structure is a READ ONLY structure from a dissector's point of view.So how do I differentiate between iterations??

Is my understanding correct ?If so what is the solution to my problem?Thanks!

Also I am using UAT for entering keys!

Did you try using the p_add_proto_data/p_get_proto_data API to store you data, as explained in doc/README.dissector file chapter 2.5?
