heif-convert works but convert doesn't in Ubuntu 23.10

Then ImageMagick might be the better place to report this.

If you have some images that also don't work with heif-convert from libheif v1.16.x, it might be because #1190 and you should upgrade to a v1.18.x.

[bobfriesenhahn]

The 'ldd' you did is for the 'convert' from ImageMagick. For GraphicsMagick you might consider 'ldd gm' (or if a modules build, on the installed heif.so module).

[bobfriesenhahn]

Under Ubuntu 22.04 LTS I see that the latest GraphicsMagick release is able to read HEIC files via libheif and libde265.

[bobfriesenhahn]

It is unlikely that anyone is going to spend any time on Ubuntu 23.10 since it is not an LTS release, and 24.04 LTS is available for upgrade now.

[farindk]

heif_decode_image() reports error "Unsupported feature: Unsupported codec"

This indicates that the codec (libde265 plugin) was not installed or not used.

[farindk]

@adrhc You can attach an image that does not work for you, but I am confident that it is just a broken installation.
