We are developing an application for Mac. This application contains two

rewrite the video game ui with FFMPeg but we need some clarification on
compliance with the LGPL. If we are compliant with the checklist on this
webpage - http://www.ffmpeg.org/legal.html - does this mean that we are
free to sell our product without paying any royalties to any third party?
And is it true that there is no license fee associated with FFMPeg?
Yes. What you have to do is comply with the LGPL, i.e. distribute
source in some way (e.g. by providing the FFmpeg source used in your
application as a source download on the same website), acknowledge the
use of FFmpeg in your installer/EULA and about dialog, and a few more.
But you don't need to pay us as long as you comply with all
requirements in that checklist.
Ron,
I find Julian's questions a little vague about what kind of "royalties"
he means. Your response applies only for copyright royalties, but not
for (possible) patent royalties.
Julian didn't even identify which codec he wants to use, so there is
insufficient information to determine if he is "free to sell our product
without paying any royalties to any third party."
