How to make ffmpeg:

Install gcc, yasm, GNU make, GNU grep dependent libraries
Set path so that GNU tools - grep, make, gcc - are found before system
Check out ffmpeg from git
run "./configure [--enable-gpl --enable-version3]"
run "make"

You do not need --enable lines for libraries that ffmpeg detects you
have installed. If you specify --enable-foo, and foo is not installed
in a way that ffmpeg (or more likely, foo) expects, then your
compilation fails. In short, do not do it!

So libass is installed, but when you try and link to it, there is a
missing reference to libiconv. libass requires libiconv, but libass's
pkgconfig pc file clearly does not state this, so ffmpeg does not link
to it. Fix libass, or specify the additional libraries you need to

./configure --extra-libs="-liconv"

With the missing library specified, configure will be able to "find"
libass, and will enable it. Repeat as necessary.

Keep re-running configure, check the output to see if the features you
require are enabled. If not, check config.log to find out why, fix the
problem, re-run configure.
