Please also look at the info collected here (which is not legal advice): https://www.ffmpeg.org/legal.html See also this excellent summary by Lou(?): https://video.stackexchange.com/a/14804 In short (and I am not a lawyer either): - ffmpeg isn't open for alternative licensing with a commercial license (as far as I know). - If you use the libav* libraries, you will have to understand whether they fall under the GPL or the LGPL (depending on build options, mainly) and what this implies for your program using the libraries. - If you use the command line tools, you probably "only" need to provide the source you used for building, and the build process, to the customers of your product which includes ffmpeg. (This surely also applies to the source of ffmpeg's non-system dependencies, other licenses may apply.) - At the same time, using ffmpeg's codecs and the likes *may* imply license costs to other owners. See the "Patent Mini-FAQ" under said link, especially the last question. Do consult a lawyer! I hope I didn't write anything totally wrong.
