DeviceProvider.deviceChanged

void deviceChanged(gst.device.Device device, gst.device.Device changedDevice)

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.

Parameters

`device`	the new version of changed_device
`changedDevice`	the old version of the device that has been updated
