Trait containing all DeviceMonitor methods.

Implementors

DeviceMonitor

Required Methods§

source

fn bus(&self) -> Bus

Gets the Bus of this DeviceMonitor

Returns

a Bus

source

fn providers(&self) -> Vec<GString> ⓘ

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.

source

fn shows_all_devices(&self) -> bool

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

Returns

true when all devices will be shown.

source

fn set_show_all_devices(&self, show_all: bool)

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

source

fn start(&self) -> Result<(), BoolError>

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.
