why a tcp stream is split into many tcp flows

[esolve esolve <esolvepolito () gmail com>]

I use tcpdump to capture video streaming and then use tcpflow to parse the
captured packets. I notice that a tcp stream is split into many tcp flows,
for the tcp flow names, for example, a tcp stream with receiver port 50552
is split into 11 flows, and in the names, the port number is changed to
50552, 50552c1, 50552c2, 50552c3,....etc

what is the reason for this?
