For HEIC specifically, we cannot install it by default because it uses
patented codecs -- but we may add it to the `ubuntu-restricted-addons`
metapackage so that it gets installed when selecting the option for
proprietary drivers in the installer.
AVIF on the other hand does seem to be just an oversight on our part.
Charles, what do you think about adding a bunch of heif plugins to
ubuntu-restricted-addons?

Since updating to Ubuntu 26.04 (gnome 50, glycin 2.1.1+ds-0ubuntu1) I'm
unable to load any HEIC images, the following is displayed when opening
in image viewer:
Remote error: org.gnome.glycin.Error.LoadingError: glycin-
loaders/glycin-heif/src/main.rs:103:24: DecoderPluginError(Unspecified)
Decoder plugin generated an error: Unspecified
stderr: Setting process memory limit
Thumbnails are also no longer generated.

- I originally raised this on the GNOME glycin project, however redirected here
as it's a dependency related issue with the package:
https://gitlab.gnome.org/GNOME/glycin/-/work_items/289
+ 1. Install the glycin-loaders update
+ 2. Open an AVIF image in Image Viewer
+ 3. Verify that the image loaded correctly

Copy pasting the response from there:
"I tested a fresh Ubuntu VM and can reproduce this. It looks like
libheif-plugin-libde265 or libheif-plugin-ffmpegdec is not installed
automatically, so you need one of these packages.
You might still want to report to Ubuntu that the dependencies for
glycin-loaders seem wrong https://packages.ubuntu.com/resolute/glycin-loaders
It looks like the suggested packages are all encoders and the decoders are
missing.
libheif-plugin-aomdec: HEIF and AVIF file format decoder and encoder
That's an AVID encode. The HEIF is confusing here, and isn't aomenc the
encoder?
libheif-plugin-x265: HEIF and AVIF file format decoder and encoder -
x265 plugin
Also sounds wrong. Why would x265 have anything to do with AVIF? And it's
also just an encoder.
It's all explained here
