hello all,
While trying to open a heic image with Ristretto (using xfce as my DE) I installed libheif. Now I can see heic thumbnails in
Thunar, and use heif-convert from the terminal successfully, but Ristretto says "Unsupported mime type".
Any idea what the issue could be? Is there anyone using Ristretto that could check on their end for me? You can find sample
heic files at https://filesamples.com/formats/heif.
It looks like libheif was linked correctly:
george@dunstan ~/.guix-profile/lib$ ls -l libheif*
lrwxrwxrwx 1 root root 70 Dec 31 1969 libheif -> /gnu/store/wvz8dzjnvgalhh74ayss6j0n1fn20ffy-libheif-1.17.6/lib/libheif
lrwxrwxrwx 1 root root 73 Dec 31 1969 libheif.so -> /gnu/store/wvz8dzjnvgalhh74ayss6j0n1fn20ffy-libheif-1.17.6/lib/libheif.so
lrwxrwxrwx 1 root root 75 Dec 31 1969 libheif.so.1 -> /gnu/store/wvz8dzjnvgalhh74ayss6j0n1fn20ffy-libheif-1.17.6/lib/libheif.so.1
lrwxrwxrwx 1 root root 80 Dec 31 1969 libheif.so.1.17.6 -> /gnu/store/wvz8dzjnvgalhh74ayss6j0n1fn20ffy-libheif-1.17.6/lib/libheif.so.1.17.6
AFAIK Ristretto should be able to work with libheif according to its doc page:
"The image types supported by Ristretto are those supported by the gdk-pixbuf library. This library itself supports a number of
basic image types (JPEG, PNG, TIFF, etc.), but then relies on optional libraries to extend the range of supported image types.
This means that you will have to install these libraries yourself to extend the range of image types supported by Ristretto.
Examples: libwmf, libopenraw, libavif, libheif, libjxl, librsvg, webp-pixbuf-loader."
thanks, George

Hi George,

I use a different set of software but that error could occur at a higher
level. Did you check your list of supported MIME types?
It may or may not be in ~/.config/mimeapps.list.
Kind regards
Felix

Thanks Felix, I do seem to have the correct entry in mimeapps.list.
image/heic=org.xfce.ristretto.desktop;
image/heif=org.xfce.ristretto.desktop;
(I added image/heic just as an experiment but it didn't change anything).
It's strange that Thunar shows the thumbnails, I might ask the xfce folks what they think.
thanks, George

It appears that, while I have libheif installed, gdk-pixbuf isn't loading the file libpixbufloader-heif.so located at
/gnu/store/wvz8dzjnvgalhh74ayss6j0n1fn20ffy-libheif-1.17.6/lib/gdk-pixbuf-2.0/2.10.0/loaders/ on my system.
I checked this looking at the default output of gdk-pixbuf-query-loaders. However if I manually create a loaders file, like
george@dunstan ~/Downloads$ gdk-pixbuf-query-loaders
/gnu/store/wvz8dzjnvgalhh74ayss6j0n1fn20ffy-libheif-1.17.6/lib/gdk-pixbuf-2.0/2.10.0/loaders/libpixbufloader-heif.so
>> my-pixbuf-loaders
&& gdk-pixbuf-query-loaders >> my-pixbuf-loaders
george@dunstan ~/Downloads$ export GDK_PIXBUF_MODULE_FILE=my-pixbuf-loaders
george@dunstan ~/Downloads$ ristretto TWNBAY_Eb
george@dunstan ~/Downloads$
I can open the heic file.
So I'm not sure where the loading process is going astray but this seems to be the issue.
Is this a bug against the packaging of libheif maybe?
George
