Running vainfo shows:

~ $ vainfo
Trying display: wayland
Trying display: x11
libva info: VA-API version 1.20.0
libva error: vaGetDriverNames() failed with unknown libva error
libva info: User environment variable requested driver 'vdpau'

      VAProfileVC1Advanced            : VAEntrypointVLD

Seems related but I don't know what's causing the failure. 

~ $ ls -l /usr/lib64/*vdpau*
lrwxrwxrwx 1 root root    31 Apr  4 18:26 /usr/lib64/libvdpau_nvidia.so ->

libvdpau.so.1.0.0
-rwxr-xr-x 1 root root 18408 Mar  1 20:47 /usr/lib64/libvdpau.so.1.0.0

No idea if any of that is relevant or not.
