The wording here was not ideal:
FFmpeg is by default licensed under LGPL and the LGPL allows to
combine open-source binaries with proprietary binaries.
So it is less "us" (the FFmpeg developers) and more the developers
of other open source projects licensed under the GPL (like especially
x264) who do not allow distribution of binaries linked against
proprietary drivers.

The BlackMagic Decklink drivers are not system libraries.
