Issue iOS18 HEIC image s previewing

[polocto]

I am sorry I so some related issues already closed #675. I am a new to nextcloud and I would like to update libheif to be able to preview HEIC images from iOS 18 but cannot find out how to update it. I already tried to update php-imagick but it is not solving my issue.

I'm not sure which way run your Nextcloud instance, but php-imagick uses dynamic linking to load the libheif library. So you have to update that using your distros package manager.

For example, on Debian Bookworm, the latest libheif1 package is version 1.15.1-1+deb12u1 and 1.18+ is what you need. Therefore, the only option right now is to enable Debian backports repo, which contains 1.19.3-1~bpo12+1.

Once you enable backports and apt install libheif1/bookworm-backports, image decoding of iOS 18 HEIF format starts working. 👍
