And how does this patch provide ffmpeg?  It adds it to the build 
environment, but what happens then?

We know it doesn't add a reference to the final ‘peek’ output (you 
can verify this yourself, assuming peek builds reproducibly).  It 
doesn't change any code in the peek binary.

So what's the mechanism by which it would work?  It will need to 
be documented.

But how exactly?  Please provide exact steps and commands.

…but in a separate patch, please.)
