Introduction to Pipewire

The pipewire package contains a server and user-space API to handle multimedia pipelines. This includes a universal API to connect to multimedia devices, as well as sharing multimedia files between applications.

This package is known to build and work properly using an LFS-11.2 platform.

Package Information

Pipewire Dependencies

Recommended

Optional

FFmpeg-5.1, Valgrind-3.19.0, Doxygen-1.9.4 and Graphviz-5.0.1 (for documentation), JACK, ldacBT, libcamera, Vulkan, WirePlumber (runtime, for running Pipewire daemon), and xmltoman

Installation of Pipewire

Install pipewire by running the following commands:

mkdir build &&
cd    build &&

meson --prefix=/usr --buildtype=release -Dsession-managers= .. &&
ninja

To test the result, issue: ninja test.

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.

-Dsession-managers=: This switch prevents automatic downloading external dependencies.

-Ddocs=true: This switch enables the generation of HTML documentation. The optional dependencies for documentation need to be installed for this to work.

-Dman=true: This switch enables the generation of manual pages. The optional dependencies for documentation need to be installed for this to work.

-Dffmpeg=enabled: This switch enables using ffmpeg for audio conversion as a SPA backend.
