Mark, you might be missing that Carl Eugen cited your [Note 1] in his 
reply.  You say "a git project requires continuous access to the 
Internet". You are mistaken about that. Which is great, because you are 
about to discover the wonders of distributed version control.

The directory *ffmpeg/* inside that archive is a git repository, your 
own local copy, requiring no connection to the internet. Carl Eugen said 
it is "current FFmpeg", but I'll bet what it is is the current FFmpeg 
source repository snapshot.  It includes commits, revision histories, 
branches, a whole lot of repository.

What happens if you move this repository to the machine which you want 
to keep free of an internet connection, and attempt to build from source 
there?

I'm afraid you overlooked something on the downloads page. The big green 
button "Download Snapshot", on the right-hand pane, links to exactly the 
<http://ffmpeg.org/releases/ffmpeg-snapshot-git.tar.bz2> URL which Carl 
Eugen cited.


So in this round at least, Carl Eugen gave you something a) helpful and 
b) responsive to your message, and were the one being dismissive.

Have fun solving the compile problems!
