Struct gstreamer::DeviceProvider
source · #[repr(transparent)]pub struct DeviceProvider { /* private fields */ }
Expand description
A DeviceProvider
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 DeviceProvider
subclass is a singleton, a plugin should
normally provide a single subclass for all devices.
Applications would normally use a DeviceMonitor
to monitor devices
from all relevant providers.
This is an Abstract Base Class, you cannot instantiate it.
Signals
provider-hidden
provider-unhidden
Object
deep-notify
The deep notify signal is used to be notified of property changes. It is typically attached to the toplevel bin to receive notifications from all the elements contained in that bin.
