The reference to patent licenses is advisory > and not a limitation on use. In essence, it says, "you can get a license here > if you want one [implicitly, if you don't, you are at your peril], but you > may not need one because most Android hardware makers already have one that > covers you." There remains some disagreement over which (if any) versions of the FDK SDK are GPL-compatible, but I see no reason for ffmpeg to assert the position that builds linking to it and to GPL code are nonredistributable. The source is available under a license widely understood to fulfill some definition of "free", and the contention around it largely comes down to a technicality. If a user or packager wants to redistribute builds with it at their own risk, I don't believe doing so would cause harm to ffmpeg's developers or community (in contrast with closed-source libraries like NDI and Decklink). --- configure | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/configure b/configure index ab761c7183..f590f30093 100755 --- a/configure +++ b/configure @@ -1727,7 +1727,6 @@ EXTERNAL_LIBRARY_GPL_LIST=" EXTERNAL_LIBRARY_NONFREE_LIST=" decklink - libfdk_aac openssl libtls " @@ -1768,6 +1767,7 @@ EXTERNAL_LIBRARY_LIST=" libdav1d libdc1394 libdrm + libfdk_aac libflite libfontconfig libfreetype
