SYNOPSIS

pw-metadata [options] [id] [key] [value] [type]

pw-metadata monitors, sets, and deletes metadata on PipeWire objects. Metadata provides key-value pairs associated with PipeWire graph objects, used for configuration and runtime state management.
The tool can operate on different metadata namespaces including "default" for general metadata and "settings" for PipeWire configuration values like log levels.

PARAMETERS

-n, --name name

Metadata name to operate on (default: "default")

-l, --list

List all available metadata objects

-m, --monitor

Monitor metadata changes continuously

-d, --delete

Delete metadata entries

-h, --help

Display help message

CAVEATS

Modifying metadata in the "settings" namespace can affect PipeWire behavior immediately. Use caution when deleting metadata as it may reset configuration to defaults.

HISTORY
