GI.Gst.Objects.DynamicTypeFactory

DynamicTypeFactory 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

C code

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

Exported types

newtype DynamicTypeFactory

Memory-managed wrapper type.
