History
Belgian software engineer Wim Taymans author of PipeWire at Red Hat in 2015

In 2015, Taymans started work on PipeWire. It was based on ideas from a couple of projects, including one called PulseVideo by William Manley.[8][9][10][11]

Christian Schaller stated "it draws many of its ideas from an early prototype by William Manley called PulseVideo and builds upon some of the code that was merged into GStreamer due to that effort."[5]

A goal was to improve handling of video on Linux the same way PulseAudio improved handling of audio.[2]

Although a separate project Taymans initially considered using name PulseVideo for the new project.[2] By June 2015, the name Pinos was being used (named after a city Wim has lived in, Pinos de Alhaurin in Spain).[5]

Initially, PipeWire only handled video streams. By early 2017, Taymans had started working on integrating audio streams. He wanted the project to support for both consumer and professional audio use cases. For advice on professional audio implementation he consulted Paul Davis and Robin Gareus. At this time the name PipeWire was adopted for the project.[8]

In November 2018, PipeWire was re-licensed from the LGPL to the MIT License.[12][13]

In April 2021, Fedora became the first Linux distribution to ship PipeWire for audio by default through its release 34.[14][15][16]

Features

The project aims include:

Reception

PipeWire has received much praise, especially among some GNOME and Arch Linux[20][21] communities. Particularly as it fixes problems that some PulseAudio users had experienced, including high CPU usage,[22] Bluetooth connection issues,[23][24] and JACK backend issues.[25]
