Hi Mortiz,
"localhost" can be resolved on the Windows PC and I am assuming port 8080 is
open for listening. I tested the port with the VLC player command I previously
mentioned. When I use the VLC command I can open the file on port 8080 on the
website.
It looks like FFmpeg has http support:

Any other thoughts or suggestions? I will keep searching Google to see if I
can find something that might help.
