GstDynamicTypeFactory
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.
