I’m opening this thread because I’m unable to open HEIC files using Gnome Image Viewer on Fedora 41.
I understand Fedora does not support HEIC out of the box for some licenses issues, that’s why I’ve already installed libheif-freeworld from RPMFusion repository:
No extra glycin loaders are needed. Fedora includes libheif loader already. The only things required from RPM Fusion are libheif-freeworld and libde265. The ffmpegdeclibheif decoder provided by libheif-freeworld is not required for HEIC decoding (yes, I tested that).
Can confirm this is also happening to me in Fedora KDE 41. I have kf6-kimageformats and heif-pixbuf-loader installed. The HEIC files I have are from an older iOS version
Interesting bug. Fedora 42 here, trying to view .heic files in the system photo viewer, and it started working once I had libheif-freeworld installed. Don’t know why it failed for OP
I have Fedora Silverblue 42 with libheif-1.19.8-1.fc42.x86_64, and can’t view a heif photo taken with an iPhone 16. The metadata is shown, but no image
