说明
spa-monitor is a small debugging utility shipped with PipeWire. It loads a SPA (Simple Plugin API) shared-object plugin and instantiates a device object from it so that developers can observe how the plugin enumerates hardware, advertises nodes, and emits events. The tool is not intended for end users; it exists to help plugin authors and PipeWire developers verify that a SPA plugin initializes correctly, exposes the expected interfaces, and reports devices on the system bus. Running spa-monitor against a plugin prints diagnostic output describing the devices discovered and any errors encountered during instantiation. Typical usage is pointing it at one of the plugin libraries under _/usr/lib/<triplet>/spa-0.2/_ to inspect how that plugin behaves on the current machine.
