I don't really understand your point, maybe I did not describe well what
I would like to do. I would like to write a dissector which is similar to
how Wireshark can open .mp3 files. The .mp3 files don't have libpcap headers
at all, but Wireshark can handle them.

My question is that is it possible to create a dissector which reads a
raw file without libpcap header?
