# GstMetaFactory

Register a GstMetaInfo 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.

## Registering a meta for dynamic loading

     static gboolean
     plugin_init (GstPlugin * plugin)
     {
       return gst_meta_factory_register (plugin, my_meta_get_info());
     }
