I see this: commit 3ff6d301b27965b23ae5cf5211920ee16d6671c2 Author: Anton Khirnov Date: Thu Oct 24 08:37:11 2024 +0200 lavfi: add frame threading infrastructure Code under AGPL, use --enable-agpl to enable. this code also has AGPL headers in source, there is no ambiguity here [...] >=20 > >And it IS stated otherwise in these files by the license header in these > >files. >=20 > It is stated that the original files were under the LGPL (or GPL), nothin= g else. Many new codecs and filters where added by Paul, and he used standard LGPL = license headers for them. Thats not a "modified existing file with LGPL" case its genuinely new files where LGPL headers where used. [...] > Fortunately, the record of changes does in fact exists: the Librempeg git= repo. But that being the case, we can't argue that you didn't notice that = the modifications didn't have a statement "otherwise".

If it come to that, the court, or more likely, FFmpeg downstre= ams and reverse dependencies, will probably base their decision on Paul's i= nferred intent, not mine, but also not yours. IANAL but according to the principle of contra proferentem, in case of ambi= guity a clause should be interpreted against the party who wrote the clause not i= n favor. That said, there is no real ambiguity, its LGPL headers, there is nothing t= hat REMOVES this license. The statement ADDS a GPL v2 license. The "unless stated otherwise" excempts the AGPL code from receiving the GPL= v2 That said, iam not sure how wise it is to discuss legal interpretations in = public.
