I have to admit it's a new feeling in programming to actually have the data, but being unable to get it to the point of the program where you need it. Makes me feel young and inexperienced again :( I did take a look at the tapping-README and I believe you are referring to register_tap_listener(...) and "the_tapinfo_struct" or in my case rtpstream_tapinfo_t The call to register_tap_listener(...) for my case is in rtp_stream.c, which is located in ...\Wireshark\gtk My tap-routines along with the global variable for the sampling-rate-defaults are in tap-rtp-common.c are inpacket-rtp.c located in ...\wireshark\epan\dissectors and finally the file where I want to use it is tap-rtp-common.c located in ...\wireshark\. I believe these 3 files result in 3 different compilation targets - I haven't been able to access the global variable for my default-sampling-rate from either of the 2 other locations. Not even when exporting it from dissectors.lib. Sorry to be so ignorant, but could you please shed some more light to get me started? Thanks - and have a nice weekend!
