Do you mean FFmpeg or ffmpeg?
If you mean ffmpeg (the application) and if your application
is not linked to libavcodec etc. but if your application simply
calls ("exec") ffmpeg, then none of the usual obligations are
relevant for your application.
Don't forget that if you distribute ffmpeg (the application)
you are responsible for providing the exact source code you
used to compile the executable (we do not offer executables,
you therefore cannot download them from FFmpeg's web page) and
you have to make sure that your users know that ffmpeg was
installed and under which license it was installed. (Please
don't claim that you "own" FFmpeg, we read this in practically
Concerning "not-modified" (just to make 100% sure): You have
the right to modify FFmpeg, it makes no difference if you
modify it or not. (I am just adding this because some people
seem to believe that it does make a difference and your
question could imply that you also think so.)
Concerning your first question: I suspect it also contains a
typo, at least I cannot parse it, please try to ask again
with a little more information.
