This is an important difference between GPLv3 and GPLv2, the latter which does not mention patents.įinally, every program is threatened constantly by software patents.

GPLv3 has anti-patent clauses it explicitly forbids the licensor from using software patents to sue or limit the freedoms of licensees. This is a messy situation created by software patents. Previous 0.10.x you must cease doing so now due to licensing issues.

Please also be aware that if you are distributing any Include binary distributions of HandBrake which include the FDK-AACĮncoder. Unfortunately due to circumstances beyond our control we can no longer Handbrake binary contains both (in a static build), and FFmpeg HI does as well.

However, that does not seem to be the case. This leads me to think that no software can be distributed in the binary form if it uses both x264 AND the all-powerful Fraunhofer FDK AAC Encoder, for example. I can see that the downloaded binary (for windows at least) is compiled with -enable-gpl and includes libx264, which is an example of piece licensed by the GPL (though it seems that x264's license is GPLv2 and ffmpeg is GPLv3 - not sure about the implications). This can be resolved by compiling ffmpeg yourself. 'non-free', and you cannot download a pre-built ffmpeg that supports Therefore these encoders have been designated as With the GPL, so the GPL does not permit distribution of binariesĬontaining code licensed under these licenses when GPL-licensed code The licenses of libaacplus, libfaac, and libfdk_aac are not compatible
