Thanks for your report!

This unfortunately isn't supported by Qt natively, yet, although there is some (old) ongoing discussion on the topic: https://bugreports.qt.io/browse/QTBUG-69212

However, there is a plugin for heif support which also has an AUR package. I was able to install this rather simply and get it running with a quick patch to the vimiv imageformats plugin in #816.

As image formats was largely developed by @jcjgraf, I would like to wait for some quick feedback before merging :blush:

[niksingh710]

will be waiting for pr to be merged.

This could be irrelevant but.

feh has support for these extra format's also if possible their integration.

Sounds good to me :+1:

I feel like we do support a lot of these, taking directly from imageheader.py:

This information is taken from the .desktop file? Possibly we don't set all the mimetypes (correctly) that we (can) support :thinking:

yep it is taken from .desktop file. i am using selectdefaultapplication for arch to set mimetypes The attached screenshot is of that application.
