qpwgraph - A PipeWire Graph Qt GUI Interface

qpwgraph is a graph manager dedicated to PipeWire, using the Qt C++ framework, based and pretty much like the same of QjackCtl.

Source code repository: https://gitlab.freedesktop.org/rncbc/qpwgraph

Upstream author: Rui Nuno Capela .

Prerequisites

qpwgraph software prerequisites for building are a C++20 compiler (g++), the Qt C++ framework (qt6-qtbase-devel or qt5-qtbase-devel) and of course the PipeWire API C development libraries and headers (pipewire-devel).

Optionally on build configure time, ALSA development libraries and headers (alsa-devel) are also required if ALSA MIDI (Sequencer) support is desired (cmake -DCONFIG_ALSA_MIDI=[1|ON]...).

Building

qpwgraph uses the CMake build system, version 3.15 or newer.

On the source distribution top directory:

cmake [-DCMAKE_INSTALL_PREFIX=] -B build
cmake --build build [--parallel ]

After successful build you may test run it immediately as follows:

build/src/qpwgraph

If you may install it permanently, then run, optionally as root:

[sudo] cmake --install build

Note that the default installation path () is /usr/local .

Enjoy.
