Error converting HEIC to JPEG

[TheGitaly]

Describe the bug
iOS 18 HEIC photos are unable to be converted by icloudpd when using parameter 'convert_heic_to_jpeg = True'.

Expected behaviour
HEIC images are converted to usable JPEG's and contained within same folder as HEIC.

Actual behaviour
Every image that conversion is attempted on results in the error "Invalid input: Unspecified: Metadata not correctly assigned to image (2.0) `/iCloud/2024/10/28/IMG_1516.HEIC' @ error/heic.c/IsHEIFSuccess/144." JPEG image is present in folder, but is 0kb in size and not an actual JPEG.

Quick Google brings up a bug report in another application using the libheif library - ImageMagick/ImageMagick#7426. Solution is to upgrade libheif - strukturag/libheif#1190

System (The following information must be entered or the issue will be closed):
QNAP QTS 5.2.0.2860
Container Station v3.0.8.981

This issue was fixed mid-September: #604

Are you sure your container is up to date?

[TheGitaly]

I pulled whatever the latest image was on the 26th to resolve the 503 error with --Initialise.

[boredazfcuk]

And you're seeing the conversion issue with this new build?

The version of libheif in the container, which it was confirmed resolves the issue, is 1.18.2-r0. This version was released in August and hasn't changed since then.

If you are still seeing the issue on the version you have installed, then the only thing I can think of, is that Apple have changed something again and it's resulting in the same issue. It will need to be fixed by the libheif package maintainers before I can include it here.

I've now pulled the version released on 3 November, and it seems to be working fine now. Are you saying you didn't change anything between this 1.24.0 and 1.24.3 version? That's strange.

Are you saying you didn't change anything between this 1.24.0 and 1.24.3 version? That's strange.

1.24.0 and 1.24.3 is the version of the icloud-photos-downloader package incorporated in the container, not the container version.

boredazfcuk/icloudpd container v1.0.979_16-09-2024 is the first version of the container which contains the iOS 18 fix. This was committed on 16th September: 22d7ad0#diff-800b827cf82b92000ae7a9ba881f387b8e570e4fc3aaf3625b9daa58c6081f79R14
...and released shortly afterwards:
https://hub.docker.com/layers/boredazfcuk/icloudpd/1.0.979_16-09-2024/images/sha256-3931c38a3adb3217b2c90c531fea29b5183b60e7c84b17339ffac2a5b26ac994?context=repo

Every container released since then has used libheif 1.18.2-r0, as libheif 1.19.2-r0 was only released yesterday, and I've not rebuilt the container to incorporate this new version yet.

So in answer to your question... no, nothing has changed regarding HEIC to JPG conversion since v1.0.979 was released on 16th September.
