libplacebo-7.349.0

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 12.3 platform.

Package Information

libplacebo Dependencies

Required

FFmpeg-7.1 and Glad-2.0.8

Recommended

Glslang-15.1.0 and Vulkan-Loader-1.4.304

Optional

Little CMS-2.17 libunwind-1.8.1, dovi_tool, Nuklear, and xxHash

Installation of libplacebo

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

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.
