Note

Development versions of BLFS may not build or run some packages properly if dependencies have been updated since the most recent stable versions of the book.

Package Information

Pipewire Dependencies

Recommended

Optional

FFmpeg-5.1, Valgrind-3.19.0, Doxygen-1.9.4 and Graphviz-5.0.0 (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.

Short Descriptions

pipewire

is a service that allows access to multimedia devices and allows sharing of multimedia files between applications

pipewire-media-session

is a service that allows a desktop environment to know when media files are being played through pipewire

pipewire-pulse

starts a Pulseaudio-compatible version of the pipewire service

pw-cat

allows you to play or record media using a pipewire instance

pw-cli

allows you to interact with a pipewire instance

pw-dot

lists all of the daemons and objects in use by pipewire
