slackbuilds/libraries/libavif

This library aims to be a portable C implementation of
AV1 image file format.It can encode and decode all AOM
supported YUV formats and bit depths.

It builds an decoder avifdec and encoder avifenc.
avifdec can convert from avif to jpeg or png image.
avifenc can encode jpeg or png to avif image.

usage:
-------

avifdec [-options] input.avif output.jpeg|jpeg|png|y4m

avifdec -h  will show help

avifenc [-options] input.jpg|jpeg|png|y4m  output.avif

avifenc -h  will show help

Note For 32-bit users:

Pandoc is an optional dependency since man pages
are disabled by default for 32-bit users.
