I am using tshark with matlab so that we can analyze the data in matlab. I recently had a problem where a UDP "blob" message was being decoded as an GVSP message, and in some instances the Field "data" was not being returned in the tshark decode. I eventually discovered that if I turned off the GVSP protocol in wireshark that the tshark decoding then worked.
Since I deliver the matlab that calls the tshark to "clients", it would be nice if I didn't have to also tell them to disable GVSP. I also deliver this to clients on both Linux and windows who may have totally different versions of wire shark installed, so to build a configuration that has GVSP disabled would be problematic.
So to get to the question is there a way that I can just define on the command line that I want all UDP messages to be decoded as UDP and nothing else?
