If you plan on investing any relevant amount of money I can
only recommend to talk to a lawyer with experience in OpenSource
and Multimedia, the way you stated your question suggests
you need a lot more information than anyone here has
time to give.
At the very least read the licenses.
Neither GPL or LGPL have any restrictions on USE,
only on DISTRIBUTION.
Even if you DISTRIBUTE commercial or not does not really matter.
As an approximation of the minimum you have to do if
distributing (if not using GPL or non-free parts):
make the source code of the EXACT version of FFmpeg you
used available alongside (e.g. on the same CD,
on the same web-page) with the binaries.
Make it possible to replace the FFmpeg version in
the thing you distribute with a different FFmpeg
version (that is mostly an issue if you link statically).
Alternative options and details: see the licenses.
