How to get the configure options of a binary package?

[littlebat <dashing.meng@gmail.com>]

Hi,

I am compiling some packages from source, so I need learning the
configure options of these packages in Debian. Is it possible to get the
configure options of a Debian binary package or Debian source package
or simply an executable binary program?

For example, when I execute "ffmpeg" in shell, it will show its
configure options, version, build time, etc.. How can I get this
information from a program?

And, how to configure the compiling options so it can show these
information when execute it in the shell?

Thanks.
