Class Details¶

class Gst.MetaFactory(**kwargs)¶

Bases:: Gst.PluginFeature
Abstract:: No
Structure:: Gst.MetaFactoryClass

Register a Gst.MetaInfo that can be automatically loaded the first time it is used.

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