public class DeviceProviderFactory
extends GstObject

A factory for DeviceProvider

See upstream documentation at https://gstreamer.freedesktop.org/data/doc/gstreamer/stable/gstreamer/html/GstDeviceProviderFactory.html

DeviceProviderFactory is used to create instances of device providers. A DeviceProviderfactory can be added to a Plugin as it is also a PluginFeature. Use the #find(java.lang.String) and {@link #get() } functions to create device provider instances or use {@link #getByName(java.lang.String) } as a convenient shortcut.

Returns the DeviceProvider of the type defined by the given device provider factory.

Returns:

DeviceProvider or NULL if the device provider couldn't be created.

getMetadata

public String getMetadata(String key)

Get the metadata on factory with key.

Parameters:

key -

the metadata with key on factory or null when there was no metadata with the given key .

hasClasses

public boolean hasClasses(String classes)

Check if factory matches all of the given classes

Parameters:

classes - a "/" separate list of classes to match, only match if all classes are matched.

Returns:

true if factory matches

Search for an device provider factory of the given name.

Parameters:

name - name of factory to find

Returns:

DeviceProviderFactory if found, or null
