I would try this library if you can based on my trust in the Ubuntu community’s ability to vote up some great posts. (It appears Debian was patching HEVC in 2019 so you may already have the libraries you need once you know what to search for...)

sudo apt install heif-gdk-pixbuf

I do not have direct experience, so I welcome a big edit here or a better answer if someone has more direct experience.
