Hi,
 
I am currently using tshark's  "-d udp.port==21000,rtp" option to tell tshark to treat UDP diagram on port 21000 as RTP packets. Can the same thing be done in capture filter. I know its doable on a captured file by using the "Decode As" feature. But can it being done in capture or display filters? Thanks for the help!
