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.DeviceProviderFactory.find and gst.device_provider_factory.DeviceProviderFactory.get functions to create device provider instances or use gst.device_provider_factory.DeviceProviderFactory.getByName as a convenient shortcut.

class DeviceProviderFactory : PluginFeature {

static gst.device_provider_factory.DeviceProviderFactory find(string name);

static gst.device_provider.DeviceProvider getByName(string factoryname);

static gst.device_provider_factory.DeviceProviderFactory[] listGetDeviceProviders(gst.types.Rank minrank);

gst.device_provider.DeviceProvider get();

gobject.types.GType getDeviceProviderType();

string getMetadata(string key);

string[] getMetadataKeys();

bool hasClasses(string classes);

bool hasClassesv(string[] classes);

}

Functions

get gst.device_provider.DeviceProvider get(): Returns the device provider of the type defined by the given device providerfactory.
getDeviceProviderType gobject.types.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.PluginFeature.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.
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 gst.device_provider_factory.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 gst.device_provider.DeviceProvider getByName(string factoryname): Returns the device provider of the type defined by the given device provider factory.
listGetDeviceProviders gst.device_provider_factory.DeviceProviderFactory[] listGetDeviceProviders(gst.types.Rank minrank): Get a list of factories with a rank greater or equal to minrank. The list of factories is returned by decreasing rank.

Inherited Members

From PluginFeature

listCopy gst.plugin_feature.PluginFeature[] listCopy(gst.plugin_feature.PluginFeature[] list): Copies the list of features. Caller should call gst_plugin_feature_list_free when done with the list.
listDebug void listDebug(gst.plugin_feature.PluginFeature[] list): Debug the plugin feature names in list.
rankCompareFunc int rankCompareFunc(const(void)* p1, const(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 gst.plugin.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 gst.plugin_feature.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.
