Description udayb 2019-07-22 09:19:53 UTC
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:

Comment 1 Nicolas Chauvet (kwizart) 2019-07-22 09:55:05 UTC
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).

Comment 2 udayb 2019-07-22 10:03:48 UTC
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.
