DynamicTypeFactory

#GstDynamicTypeFactory is used to represent a type that can be automatically loaded the first time it is used. For example, a non-standard type for use in caps fields.

In general, applications and plugins don't need to use the factory beyond registering the type in a plugin init function. Once that is done, the type is stored in the registry, and ready as soon as the registry is loaded.

Registering a type for dynamic loading

static gboolean
plugin_init (GstPlugin * plugin)
{
  return gst_dynamic_type_register (plugin, GST_TYPE_CUSTOM_CAPS_FIELD);
}

class DynamicTypeFactory : PluginFeature {

static gobject.types.GType load(string factoryname);

}

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.
