Description Dominik 'Rathann' Mierzejewski 2023-04-25 11:00:23 UTC

The HEIF file input plugin in GIMP fails to recognize a HEVC-encoded HEIF image:

$ file image1.heic 
image1.heic: ISO Media, HEIF Image HEVC Main or Main Still Picture Profile
When trying to import this file in GIMP, I get an error dialog saying "Opening image1.heic failed: Unknown file type".
This happens with libheif-1.15.1 with the libde265 decoder compiled as plugin (/usr/lib64/libheif/libheif-libde265.so):

If I downgrade libheif to 1.13.0 (which has libde265 decoder built-in), opening the same image works.

Reproducible: Always

Steps to Reproduce:
1. Install gimp-2.10.34-1
2. Install libheif-freeworld-1.15.1-5
3. Try importing a HEVC-encoded HEIF image
Actual Results:  
Import fails with "Unknown file type".

Expected Results:  
Image is imported successfully.

Still reproducible with latest build (gimp-2.10.34-5.fc39).
Could you backport that patch
(https://gitlab.gnome.org/GNOME/gimp/-/merge_requests/905)
while we're waiting for 2.10.36 to be released?

It's been over a month. I will fix the issue myself if there's no response soon.

This bug appears to have been reported against 'rawhide' during the Fedora Linux 39 development cycle.
Changing version to 39.
