You can't blame distributors for following our license.
Anyway, I think your idea about a license exception would be a good solution.
We could add a special exception to nvenc.c, allowing its use with Nvidia's
blobs, something like :
In addition, as a special exception, the copyright holders give you
permission to combine this code with free software programs or libraries
that are released under the GNU LGPL and with code included in the standard
release of the CUDA and NVENC libraries under the NVIDIA Software License
(or modified versions of such code, with unchanged license).
You may copy and distribute such a system following the terms of the GNU LGPL
for this code and the licenses of the other code concerned.
Note that people who make modified versions of this code are not obligated
to grant this special exception for their modified versions; it is their
choice whether to do so. The GNU Lesser General Public License gives
permission to release a modified version without this exception; this
exception also makes it possible to release a modified version which carries
forward this exception.
