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.
Development versions of BLFS may not build or run some packages properly if LFS or dependencies have been updated since the most recent stable versions of the books.

yasm-1.3.0 (or NASM-2.16.01)
An Internet connection is needed for some tests of this package.
Install libaom by running the following commands:
mkdir aom-build && cd aom-build && cmake -DCMAKE_INSTALL_PREFIX=/usr \ -DCMAKE_BUILD_TYPE=Release \ -DBUILD_SHARED_LIBS=1 \ -DENABLE_DOCS=no \ -G Ninja .. && ninja
To test the results, issue: 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
-DBUILD_SHARED_LIBS=1
: This switch builds shared versions of the libraries.
-DENABLE_DOCS=no
: This switch disables building the documentation because it fails due to an incompatibility with the latest version of Doxygen-1.10.0.
-DENABLE_NASM=yes
: Use this switch if you have both yasm-1.3.0 and NASM-2.16.01 installed and wish to use nasm instead of yasm.
