[SOLVED] Configuring VA_API, missing drivers?

I'm trying to enable hardware video acceleration in Firefox, I'm following the Arch Wiki to do this.

According to the wiki, when I have an Nvidia card, all I need is to set LIBVA_DRIVER_NAME=vdpau. I set this env var in .zshenv and confirmed that it is set after login.
However, running vainfo still gives me the following error:

vaInitialize failed with error code -1 (unknown libva error),exit

According to the Wiki, the driver is used as /usr/lib/dri/${LIBVA_DRIVER_NAME}_drv_video.so
But there are no files ending in _drv_video.so in the /usr/lib/dri directory.

I have the following nvidia packages installed:

lib32-nvidia-utils 495.44-1
nvidia 495.44-7
nvidia-dkms 495.44-3
nvidia-settings 495.44-1
nvidia-utils 495.44-3

You need to install libva-vdpau-driver.

You need to install libva-vdpau-driver.

Thank you, I found it unclear from the Wiki that this package was needed
