libplacebo-7.351.0

Introduction to libplacebo

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.

This package is known to build and work properly using an LFS 12.4 platform.

Package Information

libplacebo Dependencies

Required

Glad-2.0.8

Recommended

Glslang-15.4.0 and Vulkan-Loader-1.4.321

Optional

Little CMS-2.17 libunwind-1.8.2, dovi_tool, Nuklear, and xxHash

Installation of libplacebo

First, fix an incompatibility with Python-3.13.6 and later: 

sed -e '204a\    tree = ET.parse(xmlfile)'                 \
    -e 's/VkXML(ET.parse(xmlfile))/VkXML(tree.getroot())/' \
    -i src/vulkan/utils_gen.py

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

Command Explanations

--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.
