Description [src]
final class Pwg.Device : GObject.Object
{
/* No available fields */
}Live PipeWire device proxy for parameter inspection and limited parameter updates.
Device objects bind a discovered device global and expose copied parameter info and enumeration results. They can queue copied parameter updates built by this library, but they do not expose raw PipeWire proxy ownership to language bindings.
Device route parameters can be inspected and observed with this class, but route policy and default-device decisions remain the responsibility of the host session manager.
Stability: Unstable

Constructors
pwg_device_new
Creates a live device proxy wrapper for parameter inspection and limited copied parameter updates.
since: 0.1
Instance methods
pwg_device_enum_all_params
Requests read-only enumeration of all available device parameter ids.
since: 0.1
pwg_device_enum_params
Requests read-only enumeration of device parameters for id. Results are
appended to pwg_device_get_params() and emitted through the
PwgDevice::param signal.
since: 0.1
pwg_device_get_param_infos
Gets the live model of PwgParamInfo descriptors advertised by
device info events.
since: 0.1
pwg_device_get_params
Gets the live model of PwgParam values from the most recent
enumeration request.
since: 0.1
pwg_device_set_param
Queues a parameter update on the bound device. A successful return means PipeWire accepted the request for dispatch; it does not confirm that the target applied the new value. Observe later device state or parameter events when application logic needs confirmation.
since: 0.1
pwg_device_start
Binds the device proxy. If the core is not connected, this method connects it first.
since: 0.1
pwg_device_subscribe_params
Replaces the device’s active parameter subscription set with the ids in ids.
PipeWire emits copied PwgParam values through
PwgDevice::param for current subscribed values and later updates.
Passing an empty au variant clears the subscription.

Properties
Pwg.Device:params
A GListModel of PwgParam objects from the most recent
enumeration request.
since: 0.1
Signals
Pwg.Device::param
Emitted from the object’s construction thread-default main context when a device parameter enumeration result or subscribed update arrives.
since: 0.1
Signals inherited from GObject (1)
GObject::notify
The notify signal is emitted on an object when one of its properties has its value set through g_object_set_property(), g_object_set(), et al.
