The libavif package contains a library used for encoding and decoding AVIF files.

This version of BLFS may not build or run some packages properly if LFS or dependencies have been updated since the most recent stable version of the System V books.

dav1d-1.5.3 and SVT-AV1-4.0.1 (only supports YUV420)
libaom-3.13.1 (for chroma subsampling outside YUV420)
gdk-pixbuf-2.44.5, gtest, libyuv, and rav1e
An Internet connection is needed for some tests of this package. The system certificate store may need to be set up with make-ca-1.16.1 before testing this package.
Fix a build failure with SVT-AV1-4.0.0 or newer:
sed 's/enable_adaptive_quantization/aq_mode/' -i src/codec_svt.c
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_CODEC_DAV1D=SYSTEM \
-D AVIF_CODEC_SVT=SYSTEM \
-D AVIF_BUILD_GDK_PIXBUF=OFF \
-D AVIF_LIBYUV=OFF \
-G Ninja .. &&
ninja
To test the package (note that it will cause the build 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
-D
AVIF_CODEC_{AOM,DAV1D,SVT}=SYSTEM: These switches
enable using the AV1 codec via dav1d, libaom, and SVT-AV1. This
package is useless without an AV1 encoder and decoder.
-D
AVIF_BUILD_GDK_PIXBUF=OFF: This switch disables
building the AVIF loader for applications which use gdk-pixbuf. The
loader is useless when gdk-pixbuf is built with its recommended
dependency glycin.
-D AVIF_LIBYUV=OFF: Use this switch if
you have not installed libyuv.
-D AVIF_CODEC_RAV1E=SYSTEM: Use this
switch if you have installed rav1e and wish to use it as a
codec.
