The libplacebo package contains a library for processing image and video primitives and shaders. It also includes a high quality rendering pipeline that supports OpenGL and Vulkan.
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.

First, fix a build failure that occurs with glslang-15.0.0:
sed -e "20s/$/,/" \ -e "21i cxx.find_library('glslang', required: false)" \ -i src/glsl/meson.build
Install libplacebo by running the following commands:
mkdir build && cd build && meson setup .. \ --prefix=/usr \ --buildtype=release \ -D tests=true \ -D demos=false && ninja
To test the results, issue: ninja test. One test, opengl_surfaceless.c, is known to fail.
Now, as the root
user:
ninja install
--buildtype=release
:
Specify a buildtype suitable for stable releases of the package, as
the default may produce unoptimized binaries.
-D demos=false
: This switch
disables building the demo programs because building plplay is currently broken.
-D tests=true
: This switch
enables building the code necessary to run the tests.
