PipeWire

Is a new low-level 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.
