Libheif vs libheif-freeworld

Ask Fedora
1

I found out that I have both libheif-freeworld
and libheif installed.

What is the difference between these packages?
And can I remove one of them?

libheif-freeworld from RPM-Fusion probably supplements libheif with components that cannot be shipped by Fedora:

$ dnf info libheif-freeworld

This is an interesting question. Would like to know what you get “more” in the freeworld from rpmfusion.

It would make sense, yes to not to have issues with dependencies of each other. I mostly stick with Fedora as long as I not need what you get more from freeworld. Unfortunately both package descriptions point to the same git document and explain the same. Difficult to give you a clear answer.

HEVC (i.e. H.265) support needed for HEIC images. It cannot be shipped in Fedora as that codec is encumbered by patents.

libheif in Fedora provides the generic support for HEIF image containers, but only if they do not carry the HEVC payload, and use a free codec instead, like AV1 (aka AVIF image also supported by libavif), JPEG 2000, or ordinary JPEG.
