eog 3.36 cannot open HEIF files via gdk-pixbuf loader
In eog 3.34 on Ubuntu 19.10 I was able to view HEIF/HEIC files in Eye of Gnome by installing an appropriate gdk-pixbuf loader. eog 3.36 on Ubuntu 20.04 just shows the message "Could not load image <filename>. Unrecognized image file format".
The HEIF gdk-pixbuf loader itself seems to work correctly, because gcpicview is able to display HEIF images even on Ubuntu 20.04. It's just eog that doesn't seem to use the loader anymore.
I attached an example file 2020-04-11-14-45-361180.heic.
This command works and displays the file: gpicview 2020-04-11-14-45-361180.heic
This command shows the error message mentioned above: eog 2020-04-11-14-45-361180.heic
The bug was also reported in the Ubuntu bugtracker at https://bugs.launchpad.net/ubuntu/+source/eog/+bug/1873424.
