I think was Jonas is trying to say is that he has an SDP file, but the
corresponding stream it refers to isn't on the network, but rather
captured to file. Now he's trying to bring the two together.

I have absolutely no idea of how SDP works, but his file refers to
c=IN IP4 10.238.33.163
and if that could be made to point to a file's content (and ffmpeg
interpret that), that might be the solution sought after. It looks like
RFC 4566 only describes internet connections, and furthermore ffmpeg
only accepts "c=IN IP". So I fear Jonas will have to find a way to
replay his captured packets. Or is there something in there some
content in there which could be repacked into a container or raw
format, sparing the transmission via protocol?

Too much speculation,
Moritz
