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.
Install SVT-AV1 by running the following commands:
mkdir build &&
cd build &&
cmake -D CMAKE_INSTALL_PREFIX=/usr \
-D CMAKE_BUILD_TYPE=Release \
-D CMAKE_SKIP_INSTALL_RPATH=ON \
-D BUILD_SHARED_LIBS=ON \
-W no-dev -G Ninja .. &&
ninja
The test suite is very long and doesn't provide meaningful results. If you want to test the results anyway, issue:
cmake .. -D BUILD_TESTING=ON && ninja && ninja TestVectors && SVT_AV1_TEST_VECTOR_PATH=$PWD/../test/vectors \ ctest -V -O testlog.txt --timeout 10800
On a relatively slow system it's needed to increase the timeout
(see the SBU value for tests on top of the page). In the
SvtAv1ApiTests test, 12 run_paramter_check subtests are known to fail. The
test harness will download a copy of libaom (even if libaom-3.12.1
is already installed the test harness is still incapable to use the
system installation) and some videos as test inputs.
Now, as the root user:
ninja install
-D BUILD_SHARED_LIBS=ON:
This parameter forces building shared versions of the libraries.
-D
CMAKE_SKIP_INSTALL_RPATH=ON: This switch makes
cmake remove
hardcoded library search paths (rpath) when installing a binary
executable file or a shared library. This package does not need
rpath once it's installed into the standard location, and rpath may
sometimes cause unwanted effects or even security issues.
-D BUILD_TESTING=ON: This option
enables building the unit tests.
