The correct dir is <LIBDIR>/vdpau.  From here:

   http://cgit.freedesktop.org/~aplattner/libvdpau/tree/configure.ac:72

Do you have an older libvdpau.so?

We had a long debate over this internally and decided it was better to 
have the backends in a non-searchpath directory.  I believe the idea was 
to discourage directly linking to them, and to roughly follow the lead 
of OpenCL in this area, but my memory is getting foggy.  Before we made 
the switch, old NVIDIA builds of libvdpau.so looked in <LIBDIR> and 
installed libvdpau_nvidia.so there as well.

Thanks,
