Generate preview for images and videos only

[HHUBSS]

Is there a way or is it possible to generate images and videos only excluding files like pdf text, docs, excel, ppt etc?

You can explicitly enable/disable preview providers for certain file types. Have a look at the official documentation:

• Visit https://docs.nextcloud.com/server/latest/admin_manual/configuration_server/config_sample_php_parameters.html#previews
• Scroll to enabledPreviewProviders

Or do you want to apply filters to the commands of previewgenerator (pre-generate and generate-all) only?

Some apps also register their own preview providers independent of the enabledPreviewProviders (both Nextcloud Office and OnlyOffice do this). The former has nextcloud/richdocuments#1335 to implement a toggle. OnlyOffice now has a toggle under its settings from the looks of it (I have not tested it though).
