You need to save the packets you're interested in as a .pcap or .pcapng
file. Do not use Save As from Follow TCP stream. This saves only the data
stream, not the actual packets with all their headers and other
information as captured from the network.

First, apply a display filter so that only the traffic you want is
shown.

In Wireshark 1.8 or later, go to File > Export Specified Packets. In
versions of Wireshark prior to 1.8, go to File > Save As.

In either case, select the option to save only the displayed packets,
select either the .pcap or .pcapng format, give the file a name, and save
the file.
