The reason why I ask is this clause in the AGPL license: Quoting https://www.gnu.org/licenses/license-list.en.html#AGPLv3.0 : Please note that the GNU AGPL is not compatible with GPLv2. It is also technically not compatible with GPLv3 in a strict sense: you cannot take code released under the GNU AGPL and convey or modify it however you like under the terms of GPLv3, or vice versa. However, *you are allowed to combine separate modules or source files released under both of those licenses in a single project, which will provide many programmers with all the permission they need to make the programs they want.* See section 13 of both licenses for details. So, if I release FFmpeg under GPL v3, then I can also use my AGPL module with this release, and everything should be fine from a legal perspective.
