Thanks for the quick reply. One more question. How to detect/extract HTTP request in TCP payload (where TCP connection is established on the non-standard port).

Do you have a conn.log or http.log? conn.log will indicate which analyzer(s) successfully analyzed a connection and http.log will show the information from the log. dpd.log is mostly used for debugging when and why DPD failed. No failure, no log (failure includes the client or server not abiding the protocol).
You also don't need to include "-f tcp" in your filter. Bro has a wide open filter which lets everything in by default now. You also don't need to load that script. You could condense your entire command line to "bro -r mytrace.pcap"
