public class DeviceProviderFactory extends PluginFeature
#GstDeviceProviderFactory is used to create instances of device providers. A
GstDeviceProviderfactory can be added to a #GstPlugin as it is also a
#GstPluginFeature.

Use the gst_device_provider_factory_find() and
gst_device_provider_factory_get() functions to create device
provider instances or use gst_device_provider_factory_get_by_name() as a
convenient shortcut.
