What video hardware are you using?  I had brought this up before on LQ 
and it almost ignited a flame war.  The reason you are seeing the 
libvdpau_nvidia.so message is that it is hard-coded into libvdpau, and 
your video card is probably not supported by the kernel.  I had bought 
an Nvidia GTX-1050Ti card last year and got that message on both 14.2 
and then-current (4.9 kernel).  My card wasn't supported in the kernel 
until 4.13.
