PipeWire is a new multimedia framework designed from scratch that aims to provide

• graph based processing with support for feedback loops and atomic graph updates
• flexible and extensible media format negotiation and buffer allocation
• support for out-of-process processing graphs with minimal overhead
• 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.
