That's surprising to me because it's entirely possible to commercialize ffmpeg derivatives using LGPL while still complying with that license. I mean, it's well within their rights to impose whatever license they want on their software, but you shouldn't think that using ffmpeg in any closed source or commercial software is a good idea.ĮDIT: I think it's worth mentioning that none of this comes from personal experience. LGPL means no static linking, so using ffmpeg in your closed source Android/iOS apps is already completely ruled out of the picture.
