The way it is ATM, is that 1. code that is GPL in ffmpeg, everything can be merged (because it must be= GPL) 2. code that is LGPL in ffmpeg, we can merge LGPL code 3. code that is not in ffmpeg, we can include GPL and LGPL with correct headers and set gpl depandancy in configure accordingly 4. we can provide a seperate repository that includes everything and is GPL we dont have to make a choice about changing mainline to GPL Its Pauls code and he must make a choice what license he wants his code to be under. ATM most files contain LGPL headers If he chooses to actually relicense everything to GPL he has to replace these headers and he will loose users by switching to a more restrictive license. But he cannot have it both ways, if the code is LGPL then its LGPL for everybody >=20 > An agreement must involve benefits for both sides, and also allow > each side to pursue their goals.

We also cannot demand that paul waits n years before using FFmpeg code in his fork. Also this "wait n years" is really bad for the users of the codebase as it results in 2 codebases, and especially for libraries thats a pain for users The best thing would be if paul would return, and thats what I pushed for, for a long time and ive talked (emailed actually) with him and so far had no luck. We could certainly find employment for paul if he returns or also have him be the official libavfilter maintainer But IMO, if paul wants his fork to be a competing product instead then we need to treat it accordingly, the same way he competes with us. And that means we should integrate all features and bugfixes within the constraints of the licenses. thx [...] --=20 Michael GnuPG fingerprint: 9FF2128B147EF6730BADF133611EC787040B0FAB Many that live deserve death.
