Depending on your definition of problem, european people do not have
problems at all as long they follow our licenses (lgpl or gpl)

I recall some discussions with manufacturer not obeying.

Depends on where are you, what you are doing with ffmpeg and how.

For us, as long you redistribute the source of what you are using and

For patent trolls around the world much depends if you are in their
jurisdiction or not. I'd advise you to talk with your lawyer

Sorry if I confused your ideas even more ^^
