DESCRIPTION
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.

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