Overview
--------

libva-utils is a collection of tests to exercise VA-API in accordance
with the libva project. A driver implementation is necessary to properly
operate.

Requirements
------------

libva API >= 0.39.4

Google Test Framework Integration
---------------------------------

Google Test recommends it be custom compiled for each project that uses it.
Therefore, the libva-utils project tracks a subset copy of the Google
Test Framework source code at release 1.8.0 (initially) in a test/gtest/
subdirectory of the project source tree.  The libva-utils copy of gtest
will only be updated to new upstream releases (or critical upstream fixes) of
gtest, only if it is necessary.  As of this writing, the last release (1.8.0)
was August 2016, about three years after its previous release.  Thus, there
should be minimal need to update or maintain gtest within the libva-utils
project.

Building Google Test Framework Library
--------------------------------------

The Google Test Framework is compiled as a convenience library (libgtest.la)
within the libva-utils source tree.  The rules to build libgtest.la are
maintained in a custom makefile in the libva-intel-driver project tree
(see test/Makefile.am).  The libgtest.la library will be automatically compiled
if the tests are enabled by configuration.


Building Driver Tests
---------------------

The --enable-gtests=[yes|no] configuration option is defined in configure.ac to
enable or disable compilation of libgtest.la and the test_va_api test executable.
The default is disabled.  When the tests are enabled during configuration, the
make command will compile the VA-API gtests and link to libgtest.la and output/install
a single test/test_va_api or ${prefix}/bin/test_va_api executable.  Hence...

    "./autogen.sh --enable-gtests && make"

...is a minimal example of how one might build the driver and its tests.

Since all this project contains only tests, it is configurable to compile the GTest
framework and the corresponding tests.  Notice the difference when enabling
tests on other related projects, e.g. libva-intel-driver.

On the summary section after configuration something like this should be seen

libva-utils - ${LIBVA_UTILS_VERSION}

Libva VA-API version ............. : ${LIBVA_API_VERSION}
Installation prefix .............. : ${prefix}
Default driver path .............. : ${exec_prefix}/lib/dri
Extra window systems ............. : drm x11
Enable Gtests .................... : yes
