Components included:

• Codec: A HW accerlated encode/decode library
• Graphic: A HW based cross-api graphic library (Still in-developement)

1. CMake >= 3.14.0
2. Intel Graphic Driver (For Media SDK)
3. GoogleTest >= 1.8.0 (Optional, for unit tests)
4. Python 3.6 (Optional, for coding style scripts)

Set environment GTEST_ROOT or GTEST_DIR.

set GTEST_ROOT=X:/GoogleTest/include

Check CMAKE options by:

mkdir build && pushd build
cmake .. -A x64 -DCMAKE_INSTALL_PREFIX=install -L

Select the components want to build:

cmake .. -DLL_BUILD_CODEC=ON -DLL_BUILD_GFX=ON
cmake --build . --config release --target install
popd

Not tested yet.

cd build
cmake --build . --config release --target ALL_BUILD
ctest -c release -j 8 --progress

Typically, there are 2 ways to reuse a C++ project:

Build & install lltech project. This will generate a ll-config.cmake file under installation root. You can add the directory of ll-config.cmake to LL_DIR and use find_package(LL) in your cmake scripts, which will add cmake targets LL::Codec, LL::Graphic.

set(LL_DIR /path/install/lltech)
find_package(LL QUIET)
if(LL_CODEC_FOUND)
  # ...
  target_link_libraries(... PRIVATE LL::Codec)
endif()
if(LL_GFX_FOUND)
  # ...
  target_link_libraries(... PRIVATE LL::Graphic)
endif()

You can add cm4nn as a git submodule of your project, and use add_subdirectory(${LL_DIR}) to include lltech, which will add cmake targets ixr_codec, ixr_engine.

set(LL_DIR /path/source/lltech)
add_subdirectory(${LL_DIR})
target_link_libraries(... PRIVATE ixr_codec)
target_link_libraries(... PRIVATE ixr_engine)
