Just because you have mentioned it and just because
there seem to be a common misunderstanding:
It makes no difference if you changed anything or not.
You are allowed to make changes, but no matter if you
changed the code or not, your obligations if you want
to comply with the (L)GPL are the same.

Then you have to comply with everything that the GPL
requests. Note that - apart from the liability
exclusion - the GPL only applies if you distribute
binary software that is based on FFmpeg code.
So if you do not plan to distribute software binaries,
you only have to agree with the nonwarranty clause to
comply with the GPL.
