/** \page page_overview PipeWire 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.
