Description of problem: For some reason, video hardware acceleration via nouveau doesn't work out of the box. Players like vlc complain about not being able to use vdpau. Version-Release number of selected component (if applicable): libvdpau-1.2-1.fc30.x86_64 How reproducible: Always Steps to Reproduce: 1. $ vdpauinfo display: :1 screen: 0 Failed to open VDPAU backend libvdpau_nouveau.so: cannot open shared object file: No such file or directory A little searching reveals that the only package that has libvdpau_nouveau.so is mesa-vdpau-drivers. Installing that and trying vlc yields these in the log: [00005564dd594630] main libvlc: Running vlc with the default interface.

No sorry this is invalid. You need to install mesa-vdpau-drivers which isn't done by default on purpose (it requires the extracted firmware can isn't redistributable in Fedora but can be fetched from rpmfusion-nonfree-tainted repos). As a side note, the extracted firmware only works with older NVIDIA devices and might be known to have issue with current vdpau/vaapi players. You may need the proprietary driver if you want to have reliable vdpau decoding. (but feedback welcome on this point).
Thanks for the quick comment. I can confirm that it doesn't work on my Geforce 1050 Ti (GP107 - Geforce 10 series). The page here doesn't even list 10 series. https://nouveau.freedesktop.org/wiki/VideoAcceleration/ And I can confirm that it works perfectly with the proprietary driver.
