Preview generation for iOS 18 HEIC photos do fail

[2b2bff]

Even with the newest image containing Nextcloud 30.0.2 the preview of the photos captured with iOS 18 are missing. Funnily enough there is a message that you should not use Imaginary as it has known issues with HEIC files.

The issue is fixed with an upgraded libheif (1.18.0 includes the needed change) and an ImageMagick version compiled against it.

Which image are you referring to? Keep in mind we have multiple variants (Debian, Alpine)? Though I suppose it doesn't change the end result.

Our Alpine images will likely pick up libheif 1.18.x in 30-60 days when Alpine 3.21 is published.

For our Debian (Bookworm) images this is a bit trickier.

Funnily enough there is a message that you should not use Imaginary as it has known issues with HEIC files.

I believe this is no longer true. That's my understanding since nextcloud/server#37140 was merged. I think the upstream docs need to be updated.

Surprisingly, (perhaps because there was also a debian bug ticket), a backported release of libheif is available for bookworm.

However, there seems to be no activity in Imagemagick, one of the most important things. Perhaps because it is statically linked, the problem may still not be resolved?

(This issue is related to nextcloud/server#47289)

Even the official all-in-one image has no support for the new HEIC, yet...
