Posts a message on the provider's #GstBus to inform applications that a new device has been added.
This function is used when changed_device was modified into its new form device. This will post a DEVICE_CHANGED message on the bus to let the application know that the device was modified. #GstDevice is immutable for MT. safety purposes so this is an "atomic" way of letting the application know when a device was modified.
Posts a message on the provider's #GstBus to inform applications that a device has been removed.
Gets the #GstBus of this #GstDeviceProvider
Gets a list of devices that this provider understands. This may actually probe the hardware if the provider is not currently started.
Retrieves the factory that was used to create this device provider.
Get the provider factory names of the #GstDeviceProvider instances that are hidden by provider.
Get metadata with key in provider.
Make provider hide the devices from the factory with name.
This function can be used to know if the provider was successfully started.
Starts providering the devices. This will cause #GST_MESSAGE_DEVICE_ADDED and #GST_MESSAGE_DEVICE_REMOVED messages to be posted on the provider's bus when devices are added or removed from the system.
Decreases the use-count by one. If the use count reaches zero, this #GstDeviceProvider will stop providering the devices. This needs to be called the same number of times that gst.device_provider.DeviceProvider.start was called.
Make provider unhide the devices from factory name.
Create a new device providerfactory capable of instantiating objects of the type and add the factory to plugin.
Checks to see if there is any object named name in list. This function does not do any locking of any kind. You might want to protect the provided list with the lock of the owner of the list. This function will lock each #GstObject in the list to compare the name, so be careful when passing a list with a locked object.
A default deep_notify signal callback for an object. The user data should contain a pointer to an array of strings that should be excluded from the notify. The default handler will print the new value of the property using g_print.
Atomically modifies a pointer to point to a new object. The reference count of oldobj is decreased and the reference count of newobj is increased.
Attach the #GstControlBinding to the object. If there already was a #GstControlBinding for this property it will be replaced.
A default error function that uses glib.global.printerr to display the error message and the optional debug string..
Gets the corresponding #GstControlBinding for the property. This should be unreferenced again after use.
Obtain the control-rate for this object. Audio processing #GstElement objects will use this rate to sub-divide their processing loop and call gst.object.ObjectGst.syncValues in between. The length of the processing segment should be up to control-rate nanoseconds.
Gets a number of #GValues for the given controlled property starting at the requested time. The array values need to hold enough space for n_values of #GValue.
Returns a copy of the name of object. Caller should glib.global.gfree the return value after usage. For a nameless object, this returns null, which you can safely glib.global.gfree as well.
Returns the parent of object. This function increases the refcount of the parent object so you should gst.object.ObjectGst.unref it after usage.
Generates a string describing the path of object in the object hierarchy. Only useful (or used) for debugging.
Gets the value for the given controlled property at the requested time.
Check if the object has active controlled properties.
Check if object has an ancestor ancestor somewhere up in the hierarchy. One can e.g. check if a #GstElement is inside a #GstPipeline.
Check if object has an ancestor ancestor somewhere up in the hierarchy. One can e.g. check if a #GstElement is inside a #GstPipeline.
Check if parent is the parent of object. E.g. a #GstElement can check if it owns a given #GstPad.
Removes the corresponding #GstControlBinding. If it was the last ref of the binding, it will be disposed.
This function is used to disable the control bindings on a property for some time, i.e. gst.object.ObjectGst.syncValues will do nothing for the property.
This function is used to disable all controlled properties of the object for some time, i.e. gst.object.ObjectGst.syncValues will do nothing.
Change the control-rate for this object. Audio processing #GstElement objects will use this rate to sub-divide their processing loop and call gst.object.ObjectGst.syncValues in between. The length of the processing segment should be up to control-rate nanoseconds.
Sets the name of object, or gives object a guaranteed unique name (if name is null). This function makes a copy of the provided name, so the caller retains ownership of the name it sent.
Sets the parent of object to parent. The object's reference count will be incremented, and any floating reference will be removed (see gst.object.ObjectGst.refSink).
Returns a suggestion for timestamps where buffers should be split to get best controller results.
Sets the properties of the object, according to the #GstControlSources that (maybe) handle them and for the given timestamp.
Clear the parent of object, removing the associated reference. This function decreases the refcount of object.

A #GstDeviceProvider subclass is provided by a plugin that handles devices if there is a way to programmatically list connected devices. It can also optionally provide updates to the list of connected devices.
Each #GstDeviceProvider subclass is a singleton, a plugin should normally provide a single subclass for all devices.
Applications would normally use a #GstDeviceMonitor to monitor devices from all relevant providers.
