VDPAU Batteries Not Included

[tbelway]

Describe the bug

VDPAU is broken as reported by vdpauinfo:

vdpauinfo 
display: :0   screen: 0
Failed to open VDPAU backend libvdpau_radeonsi.so: cannot open shared object file: No such file or directory
Error creating VDPAU device: 1

This is tested both on a laptop with intel iGPU and with a desktop with an AMD Radeon RX6000 series card.

What did you expect to happen?

I would expect vdpau to be functional.

Extra information or context

VAAPI is working as expected.

Is there a reason you need the older legacy media API when VAAPI is available? Just like we use Wayland and don't ship X11 we're trying to undo the mistakes of the past and not ship garbage.

Mostly for legacy games and NVIDIA compatibility. I have converted a few friends to linux gaming and one of them has an NVIDIA card so I'm prepping for that. :)
Perhaps I should actually switch them from Nobara to bazzite first and then see if there issues before requesting VDPAU given it's predominantly legacy and NVIDIA.
