That package contains more than the headers.

We don't add any code, the headers itself carry this copyright
statement:

/*

 */

We can now argue if these two header files qualify as "Software". I
don't think that NVIDIA would insist on having this enforced at court,
but in order to be safe (and play nicely) this copyright notice should
be copied to debian/copyright, so that it ends up in the copyright files
of the binary packages. I don't see that it would change the license of
the package and therefore I think it should be OK.

Technicalities: the vdpau adaption library is loaded via dlopen(). This
library ATM is statically configured to use the nvidia implementation
(this is the non-free part), but it was designed so that other vendors
could implement their own version of vdpau. I don't see anything that
would violate neither the letter nor the spirit of the GPL here.
