Converting heic file fails

magick xyz.heic xyz.jpeg

Works here also

For me the key is libheif-HEIFfrom Packman; removing that single package makes every graphics app to error out, including GIMP even when gimp-plugin-heif from Packman is installed (an encoder rather than a decoder?)

@swannema

I do not use packman at all, so that can not be it. I have the vlc repo enabled and from there I use ffmpeg8/7, vlc, libx265 and libx264.
For a long time I needed the heif packages from packman but since a couple of weeks that is no longer necessary

Interesting, but there should be something else going on, possibly a HW decoder enabled on your HW by a recent Mesa, Vulkan or something? The glycin-loaders package does not avoid the errors here.

@dcurtisfra

But Mozilla Firefox displays the thumbnails on the HEIC sample gallery web site correctly.

The thumbnails are actually .jpeg images, so no surprise about that, see the actual link to one of those: https://heic.digital/img/samples/mini-shelf-christmas-decoration.jpg

My hardware is so old it doesn’t support hevc decoding, I really do not know why it works, I even have it working in a tumbleweed vm, that was actually where I discovered that it works without packman, the vm has never seen a packman package but both use the vlc repo.
It was a pleasant surprise.

Mystery solved: ffmpeg-8 (and associated libav*) from both Packman and VLC apparently include an HEIF decoder, so apparently if you have one or the other you don’t need libheif-HEIF from Packman.

Either way, if you have a pure OSS install you cannot decode, display, convert .heic files.

[OrsoBruno]

Basically an .heic file contains images with HEVC encoding (aka ITU-T H.265) so any ffmpeg with H265 decoders can decode such images.
The OSS version of ffmpeg has H.265 disabled due to patent issues.

The Packman libheif-HEIF might decode an even wider range of images since .heic files are a default special case of HEIF container and encoding.

Please see Wikipedia if you are interested in the details.

Bruno, on this Tumbleweed system, installing “libheif-HEIF” (in the Packman essential repository) replaced the following openSUSE:repo-oss packages with packages from Packman essentials –

• libheif1, gdk-pixbuf-loader-libheif, libheif-svtenc, libheif-openh264, libheif-aom, libheif-rav1e, libheif-ffmpeg, libheif-jpeg, libheif-openjpeg, libheif-dav1d.

Gwenview, Okular, showFoto and GIMP now open the HEIC images I mentioned above perfectly and, also the HEIC sample gallery files.

• Krita doesn’t – for whatever reason – I’ll investigate later – it may well be that Krita is still KDE Plasma 5 – they have announced that, they’re moving to KDE Plasma 6 but, they aren’t there yet …

Bruno, many, many thanks for the hint.
