It seems that a lot of concepts are being mixed here-

What are you actually trying to do? Run ffmpeg in a VM or in windows? 
Serve content outbound or play something?

That's just the start-up message, there could be a -lot- more.

server? It you're trying to play something from a link it must point to 
the source (thus the IP is definitely wrong). If you're trying make it 
available to another player, nothing to play is specified.

You don't need to use powershell to run the windows executables, cmd.exe 
is fine.

What part does the VM ubuntu play in this? How does ffmpeg behave when 
running in the VM?

(Please copy/paste the command output into the body of the email instead 
of doing screen captures, that's much easier for people to see).
