The libaom package contains a reference version of the Alliance for Open Media video codec. This codec is a patent free alternative to H.265, and is starting to be used throughout the internet.
![[Note]](../images/note.png)
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 before testing this package.
This may take a while to build. Feel free to do something else while this is building.

Install libaom by running the following commands:
mkdir aom-build &&
cd aom-build &&
cmake -D CMAKE_INSTALL_PREFIX=/usr \
-D CMAKE_BUILD_TYPE=Release \
-D BUILD_SHARED_LIBS=1 \
-D ENABLE_DOCS=no \
-G Ninja .. &&
ninja
To test the results, issue: ninja testdata && ninja runtests. Note that the tests take an extremely long time to run.
Now, as the root user:
ninja install && rm -v /usr/lib/libaom.a
Install lib32-libaom by running the following commands:
rm -rf * &&
CC="gcc -m32" CXX="g++ -m32" \
PKG_CONFIG_PATH=/usr/lib32/pkgconfig \
cmake -D CMAKE_INSTALL_PREFIX=/usr \
-D CMAKE_INSTALL_LIBDIR=lib32 \
-D CMAKE_BUILD_TYPE=Release \
-D BUILD_SHARED_LIBS=1 \
-D ENABLE_DOCS=no \
-G Ninja .. &&
ninja
Now, as the root user:
DESTDIR=$PWD/DESTDIR ninja install && cp -vR DESTDIR/usr/lib32/* /usr/lib32 && rm -v /usr/lib32/libaom.a && rm -rf DESTDIR && ldconfig
Inspect CMakeLists.txt and other
CMake related files for a full
list of options.
-D BUILD_SHARED_LIBS=1:
This switch builds shared versions of the libraries.
-D ENABLE_DOCS=no: This
switch disables building the documentation because doxygen is not installed.
