Description Daniel Novomeský 2020-02-28 10:20:37 UTC
I would like that gentoo has support for AV1 Image File Format (AVIF). It is a new image format which I use already because it is much better than traditional JPG. Netflix wrote about this format too:

There is a libavif available to handle AVIF format:
I use libavif in my open-source programs (like ) and I also use gentoo (since 2005).

The git master of media-gfx/darktable already uses libavif, so adding package like media-libs/libavif will be needed sooner or later.

Would it be acceptable to add libavif to gentoo?

libavif itself is a portable C code but it has optional dependencies. It is necessary to choose at least one of them during build time. libavif can optionally use:
media-libs/libaom (but it has to be enough fresh snapshot from git at least v1.0.0-errata1-avif)
or libgav1 (not in portage yet, )

On my computer I typically configure libavif to use media-libs/libaom-9999 only (as libaom has both AV1 decoder and encoder, dav1d&libgav1 are only decoders, rav1e is only encoder). Other developers prefer to use combination of dav1d & rav1e.

I observed that after upgrading media-libs/libaom-9999 I have to rebuild libavif so my programs continue to work correctly.

I did not create any .ebuild yet

Initial version of ebuild

I started to learn how to make ebuilds, attaching first version.

improved ebuild

The new version of the ebuild provides following tools too:

dav1d, libaom
are optional use flags. At least one of them must be selected.

libaom-1.0.0 is not good for AVIF. It should be one of the newer snapshots, at least 1.0.0-errata1-avif
Comment 3 Aaron W. Swenson gentoo-dev 2020-03-31 19:47:00 UTC
Good start!

CMAKE_ECLASS=cmake doesn't have an impact on anything. Remove it.

src_install doesn't deviate from the default. So, you can exclude the function altogether.

I'd move the libaom warning to either pkg_postinst() if it's a short emerge or pkg_pretend() if it's a long emerge.

SRC_URI should make use of ${PV}. This will make it easy to version bump later.

Thank you for the feedback.
I made few edits.

Comment 7 Daniel Novomeský 2020-04-08 19:28:16 UTC
libavif can optionally use rav1e too (instead of libaom), but we need media-video/rav1e to install C API library first. See

Ebuild using rav1e's C API

media-video/rav1e now produce C API used by libavif, so this is new ebuild which is capable to optionally use the API.

Package was added to ::gentoo
