DeviceProviderFactory

#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.

class DeviceProviderFactory : PluginFeature {

protected

GstDeviceProviderFactory* gstDeviceProviderFactory;

GstDeviceProviderFactory* getDeviceProviderFactoryStruct(bool transferOwnership);

void* getStruct();

this(GstDeviceProviderFactory* gstDeviceProviderFactory, bool ownedRef);

static GType getType();

static DeviceProviderFactory find(string name);

static DeviceProvider getByName(string factoryname);

static ListG listGetDeviceProviders(GstRank minrank);

DeviceProvider get();

GType getDeviceProviderType();

string getMetadata(string key);

string[] getMetadataKeys();

bool hasClasses(string classes);

bool hasClassesv(string[] classes);

}

Constructors

this this(GstDeviceProviderFactory* gstDeviceProviderFactory, bool ownedRef): Sets our main struct and passes it to the parent class.

Functions

get DeviceProvider get(): Returns the device provider of the type defined by the given device providerfactory.
getDeviceProviderFactoryStruct GstDeviceProviderFactory* getDeviceProviderFactoryStruct(bool transferOwnership): Get the main Gtk struct
getDeviceProviderType GType getDeviceProviderType(): Get the #GType for device providers managed by this factory. The type can only be retrieved if the device provider factory is loaded, which can be assured with gst_plugin_feature_load().
getMetadata string getMetadata(string key): Get the metadata on @factory with @key.
getMetadataKeys string[] getMetadataKeys(): Get the available keys for the metadata on @factory.
getStruct void* getStruct(): the main Gtk struct as a void*
hasClasses bool hasClasses(string classes): Check if @factory matches all of the given @classes
hasClassesv bool hasClassesv(string[] classes): Check if @factory matches all of the given classes

Static functions

find DeviceProviderFactory find(string name): Search for an device provider factory of the given name. Refs the returned device provider factory; caller is responsible for unreffing.
getByName DeviceProvider getByName(string factoryname): Returns the device provider of the type defined by the given device provider factory.
getType GType getType()
listGetDeviceProviders ListG listGetDeviceProviders(GstRank minrank): Get a list of factories with a rank greater or equal to @minrank. The list of factories is returned by decreasing rank.

Variables

gstDeviceProviderFactory GstDeviceProviderFactory* gstDeviceProviderFactory;: the main Gtk struct

Inherited Members

From PluginFeature

gstPluginFeature GstPluginFeature* gstPluginFeature;: the main Gtk struct
getPluginFeatureStruct GstPluginFeature* getPluginFeatureStruct(bool transferOwnership): Get the main Gtk struct
getStruct void* getStruct(): the main Gtk struct as a void*
getType GType getType()
listCopy ListG listCopy(ListG list): Copies the list of features. Caller should call @gst_plugin_feature_list_free when done with the list.
listDebug void listDebug(ListG list): Debug the plugin feature names in @list.
listFree void listFree(ListG list): Unrefs each member of @list, then frees the list.
rankCompareFunc int rankCompareFunc(void* p1, void* p2): Compares the two given #GstPluginFeature instances. This function can be used as a #GCompareFunc when sorting by rank and then by name.
checkVersion bool checkVersion(uint minMajor, uint minMinor, uint minMicro): Checks whether the given plugin feature is at least the required version
getPlugin Plugin getPlugin(): Get the plugin that provides this feature.
getPluginName string getPluginName(): Get the name of the plugin that provides this feature.
getRank uint getRank(): Gets the rank of a plugin feature.
load PluginFeature load(): Loads the plugin containing @feature if it's not already loaded. @feature is unaffected; use the return value instead.
setRank void setRank(uint rank): Specifies a rank for a plugin feature, so that autoplugging uses the most appropriate feature.
