Trait containing all DeviceMonitor methods.

Implementors

DeviceMonitor

Required methods

Gets the Bus of this DeviceMonitor

Returns

a Bus

Gets a list of devices from all of the relevant monitors. This may actually probe the hardware if the monitor is not currently started.

Returns

a GList of Device

Get a list of the currently selected device provider factories.

This

Returns

A list of device provider factory names that are currently being monitored by self or None when nothing is being monitored.

Get if self is currently showing all devices, even those from hidden providers.

Returns

true when all devices will be shown.

Set if all devices should be visible, even those devices from hidden providers. Setting show_all to true might show some devices multiple times.

show_all

show all devices

Starts monitoring the devices, one this has succeeded, the GST_MESSAGE_DEVICE_ADDED and GST_MESSAGE_DEVICE_REMOVED messages will be emitted on the bus when the list of devices changes.

Returns
