> We want to integrate ffmpeg.exe in our application

What do you mean with "integrate"? And what exactly do you
want to integrate?
I ask because I find it difficult to integrate an executable in
an application but if you are really just distributing an ffmpeg
executable that is called with file names as parameters from
your application, the (L)GPL does not effect your application.

> Also, we want to deliver ffmpeg.exe with our installer package.

Don't forget to tell your users that your installer installs FFmpeg.
Don't forget to tell your users that FFmpeg is distributed under
the GPL and show them the GPL. (This assumes you compiled
with --enable-gpl, if not, the LGPL applies.)
Either make the exact FFmpeg source code you used to compile
the binary you are distributing part of your installer or provide it
at the same download page where your installer can be found.
If your EULA claims that your software belongs to you (I
expect your EULA to claim this), make it crystal-clear that
you do not own FFmpeg and where FFmpeg can be found.

This assumes that you are distributing a stand-alone binary
of the ffmpeg application, not libraries that you call from your
(It also assumes you are not using a funny work-around
that does not "use" the libraries directly but actually does
through some trick. Calling the ffmpeg executable and
passing file names as parameters is not such a trick.)

I am not a lawyer, ask your lawyer if you need legal advice.
