Struct gstreamer::DeviceProvider

pub struct DeviceProvider(_, _);

A DeviceProvider subclass is provided by a plugin that handles devices if there is a way to programatically 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.

Methods

impl DeviceProvider

pub fn register<'a, P: Into<Option<&'a Plugin>>>(     plugin: P,     name: &str,     rank: u32,     type_: Type ) -> bool

Create a new device providerfactory capable of instantiating objects of the type_ and add the factory to plugin.

plugin

Plugin to register the device provider with, or None for a static device provider.

name

name of device providers of this type

rank

rank of device provider (higher rank means more importance when autoplugging)

type_

GType of device provider to register

Returns

true, if the registering succeeded, false on error
