The GA has the full text and that is much more detailed. Iam posting the relevant parts so the whole community can see it. "a claim that there is GPLv2 code in a file of FFmpeg origin that has the LGPLv2.1 license would be a breach of the FFmpe= g's LGPLv2.1 license. While section 3 of the LGPLv2.1 would have allowed him to take the original FFmpeg files and change the license for them to GPLv2, he didn't follow the necessary steps to effectively change the license. So the original code he is building from is still under LGPLv2.1. Since code contributions to a copyleft work have to be under the /same /license as the code you are contributing to (Section 2(c), "You must cause the whole of t= he work to be licensed at no charge to all third parties under the terms of t= his License"), Paul's contributions to LGPLv2.1 files are under the LGPLv2.1 license because he didn't exercise the option to change them to GPLv2 firs= t. A claim otherwise would be admitting he is in breach of the FFmpeg license." "You can safely assume that any new file he created with a license identifier in the file of LGPLv.2.1 is under the LGPLv2.1 license." "Paul's response to your use of his code may be to relicense his code under the AGPL,* but he cannot change the license retroactively - you would have= to accommodate the AGPL license for any later changes you adopt, but not for = any code you are using from before a license change." thx [...] --=20 Michael GnuPG fingerprint: 9FF2128B147EF6730BADF133611EC787040B0FAB I know you won't believe me, but the highest form of Human Excellence is to question oneself and others. -- Socrates --EXR5tKr3ta0ATDTL Content-Type: application/pgp-signature; name="signature.asc" -----BEGIN PGP SIGNATURE----- iF0EABEKAB0WIQSf8hKLFH72cwut8TNhHseHBAsPqwUCaKolhwAKCRBhHseHBAsP q+OYAKCbosEZzOkKeXJDAulqO3B8TLazqQCghGMApx4GDSCE7dTVGa0ciQg+RX8= =/Cyu -----END PGP SIGNATURE----- --EXR5tKr3ta0ATDTL-- --===============3576658186976625434== Content-Type: text/plain; charset="us-ascii" MIME-Version: 1.0 Content-Transfer-Encoding: 7bit Content-Disposition: inline _______________________________________________ ffmpeg-devel mailing list ffmpeg-devel@ffmpeg.org https://ffmpeg.org/mailman/listinfo/ffmpeg-devel To unsubscribe, visit link above, or email ffmpeg-devel-request@ffmpeg.org with subject "unsubscribe". --===============3576658186976625434==--
