I have written a compression codec that I am releasing under the AGPL.
I would like to link it with FFmpeg, a video streaming application. FFmpeg is licensed under the LGPL, but since it supports some GPL v2 codecs, it can also be licensed under GPLv2. But not GPLv3.
So, in order to link my codec with FFmpeg, I will re-release FFmpeg under AGPL.
My question is : how to set up the license for this.
FFmpeg has two different license files to cover both LGPL and GPLv2.
I will now add a third AGPL license, which shall apply to all of the code (Of course, the LGPL and GPLv2 licenses continue to be in force)
So, how do I word the AGPL to acknowledge the other two licenses ?
