/** \page page_overview Overview
|
|
|
|
PipeWire is a new low-level multimedia framework designed from scratch that
|
|
aims to provide:
|
|
|
|
- Graph based processing.
|
|
- Support for out-of-process processing graphs with minimal overhead.
|
|
- Flexible and extensible media format negotiation and buffer allocation.
|
|
- Hard real-time capable plugins.
|
|
- Achieve very low-latency for both audio and video processing.
|
|
|
|
The framework is used to build a modular daemon that can be configured to:
|
|
|
|
- Be a low-latency audio server with features like PulseAudio and/or JACK.
|
|
- A video capture server that can manage hardware video capture devices and
|
|
provide access to them.
|
|
- A central hub where video can be made available for other applications
|
|
such as the gnome-shell screencast API.
|
|

# Motivation
|
|
|
|
Linux has no unified framework for exchanging multimedia content between
|
|
applications or even devices. In most cases, developers realized that
|
|
a user-space daemon is needed to make this possible:
|
|
|
|
- For video content, we typically rely on the compositor to render our
|
|
data.
|
|
- For video capture, we usually go directly to the hardware devices, with
|
|
all security implications and inflexible routing that this brings.
|
|
- For consumer audio, we use PulseAudio to manage and mix multiple streams
|
|
from clients.
|
|
- For Pro audio, we use JACK to manage the graph of nodes.
|
|
|
|
None of these solutions (except perhaps to some extent Wayland) however
|
|
were designed to support the security features that are required when
|
|
dealing with flatpaks or other containerized applications. PipeWire
|
|
aims to solve this problem and provides a unified framework to run both
|
|
consumer and pro audio as well as video capture and processing in a
|
|
secure way.
