Oh ok, thanks you very much! Maybe the "--enable-nonfree" option should be a bit clearer on this point. When I read it I thought I could freely use every format supported by my "free" build without any patent concern. Well.. therefore I suppose that if I don't want to have issues with the patent holders, I should disable all of the encoders and decoders by default, and let the end-developer choose which decoder he wants to use. With this way the developer is the only one responsible for the possible license fees.
