Thanks for the reminder, I have forgotten about this thread until now.
I recall looking into this further after this and was informed that
vdpau will fall back to nvidia as a last resort when all else fails.

As you suggested a newer kernel could help.

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.

I did read it and I read it again, this is the first that you mentioned
that you do not have nvidia hardware, but you are right that makes the
issue sound different. I wonder why its trying to use
libvdpau_nvidia.so regardless? Perhaps this is a red herring? I am not
familiar with vlc.

Another idea is that this is related to DRI2 in which case I would
suggest trying the modesetting xorg driver (Part of xorg-server) and /
or DRI3. You could also try newer versions of xorg and mesa, but this
would be more involved to test.

Chris, Ozab, orbea, reread my original post, particularly 'I don't even 
have any
Nvidia hardware,' and I never had on this PC. None what you said has 
anything to do with it.  You all missed that there's an earlier line, 
'libEGL warning: DRI2: failed to authenticate,' and other error lines.  
VLC may now be built to use more parts of display hardware, and Nvidia 
is just something it checks for but is n/a. I'm using an AMD Radeon RX 
Vega 64 with kernel 4.18.11, but I don't think the AMD 3D drivers are 
ready for Slackware 14.2... and unfortunately VLC doesn't give me an 
option to not use such parts that make it crash.

Yes, the nvidia driver is incorrectly installed. The issue is
specifically that libvdpau_nvidia.so does not exist. I would suggest
removing nvidia, cleaning up any broken symlinks left behind (See the
README), reinstalling xorg-server, mesa and then nvidia.
Alternatively with an older gpu nouveau may work just fine.

It looks more like a nvidia driver problem. Check wheater the dravier
installed correctly.

I googled for:
vlc Failed to open VDPAU backend libvdpau_nvidia.so: cannot open shared
object file: No such file or directory

which turned up a bunch of similar problems  and some solutions (not all
vlc related). I can't tell which of them may relate to your situation,
so won't try to summarise all the possibilities here but suggest, if you
haven't already,  you do the same search and try some of the suggested
solutions.
