[solved] Error setting up memories app video: Cannot load libcuda.so.1

Nextcloud version (eg, 20.0.5): 25.0.4
Operating system and version (eg, Ubuntu 20.04): Ubuntu 22.04
Apache or nginx version (eg, Apache 2.4.25): apache/2 4.52
PHP version (eg, 7.4): 8.1.2

The issue you are facing:
Running the occ memories:video-setup command shows only some HTTP error 408
looking at the logs, it seems that the app assumes it can use NVIDIA drivers and it tries to load libcuda, but it can’t…

Is this the first time you’ve seen this error? (Y/N):N

Steps to replicate it:

  1. run the occ command.
/var/www/nextcloud$ sudo -u www-data php occ memories:video-setup
ffmpeg is installed
ffprobe is installed
Checking for go-vod binary
Trying go-vod from /var/www/nextcloud/apps/memories/exiftool-bin/go-vod-amd64
go-vod is installed!

You can use transcoding and HLS streaming
This is recommended for better performance, but has implications if
you are using external storage or run Nextcloud on a slow system.

Read the following documentation carefully before continuing:

Do you want to enable transcoding and HLS? [Y/n]

found the solution myself: you need the intel-media-va-driver-non-free package
