Description

Hi there,

I like to use nextcloud within a cloud hosting. Because the s3 storage is much cheaper, I would prefer s3 primary storage. Now I found the issue, that in s3 storage the preview generation for videos doesn`t work.

When I switch to local storage, the preview generation works perfectly for the same test video.

1st: How can I debug the issue?
2nd: What can I do to fix the issue?

Best regards

No files, tests, or entry points are named in the issue. Start by reproducing video preview generation with S3 primary storage and compare it with local storage, then inspect the available logs and configuration. Done means video thumbnails are generated successfully on S3 without breaking local storage.
