I'd do that anyway; it's pretty much unenforceable, at least in the USA and 
probably Europe, and tells people that they won't have to look very hard to 
see how things work.

The first stop for ffmpeg license questions is 
https://ffmpeg.org/legal.html, and for (L)GPL questions is the FAQs linked 
above.
