![]() : Fedora has since adopted a more defensive posture to patent language, making it not AllowedĪfterburner is "a type of analysis by synthesis algorithm which increases the audio quality but also the required processing power." Fraunhofer recommends to always activate this feature. (The AAC patent license covers both encoder and decoder, so using fdk_aac does not add patent violations to FFmpeg.) The position of FFmpeg is that although the license is GPL-incompatible (and therefore nondistributable with GPL parts), it is acceptable to distribute the library with LGPL parts. ![]() Debian does not comment on the patent situation. This license puts a limitation on charging for software that includes the library, leading Debian to consider it non-free. Considering the patent terms, all AAC software are indeed equally affected. The Free Software Foundation (FSF) considers it fishy to have an invitation to purchase patent licenses in the text, but concedes that "any program is potentially threatened by patents". ![]() As this governs use, it should not have anything to do with distribution. It goes on to say "you may use this FDK AAC Codec software or modifications thereto only for purposes that are authorized by appropriate patent licenses". The license included by Fraunhofer in the FDK source code specifically allows distribution in source or binary forms, but does not license patented technologies described by the source code.
