Package Information

libavif Dependencies

Required

libaom-3.9.1

Recommended

Optional

gtest, libdav1d, libyuv, rav1e, and svt-av1

[Note]

Note

An Internet connection is needed for some tests of this package.

Installation of libavif

Install libavif by running the following commands: 

mkdir build &&
cd    build &&

cmake -D CMAKE_INSTALL_PREFIX=/usr \
      -D CMAKE_BUILD_TYPE=Release  \
      -D AVIF_CODEC_AOM=SYSTEM     \
      -D AVIF_BUILD_GDK_PIXBUF=ON  \
      -D AVIF_LIBYUV=OFF           \
      -G Ninja .. &&
ninja

To test the package (note that it will cause the building system to download a copy of gtest and build the test suite with the copy), issue: 

cmake .. -D AVIF_GTEST=LOCAL -D AVIF_BUILD_TESTS=ON &&
ninja && ninja test

Now, as the root user: 

ninja install

The AV1 format needs to be added to the loaders cache. As the root user: 

gdk-pixbuf-query-loaders --update-cache

Command Explanations

-D AVIF_CODEC_AOM=SYSTEM: This switch enables using the AOM codec. This package is useless without at least one codec built in.

-D AVIF_BUILD_GDK_PIXBUF=ON: This switch builds the AVIF loader for applications which use gdk-pixbuf. Remove it if you have not installed gdk-pixbuf-2.42.12.

-D AVIF_LIBYUV=OFF: Use this switch if you have not installed libyuv.

-D AVIF_CODEC_DAV1D=SYSTEM: Use this switch if you have installed libdav1d and wish to use it as a codec.

-D AVIF_CODEC_RAV1E=SYSTEM: Use this switch if you have installed rav1e and wish to use it as a codec.

-D AVIF_CODEC_SVT=SYSTEM: Use this switch if you have installed svt-av1 and wish to use it as a codec.
