Value:

        static struct ClassName##Registrar { \
                ClassName##Registrar() { \
                        MediaNode::registerNodeType(#ClassName, []() -> MediaNode * { return new ClassName(); }); \
                } \
        } __##ClassName##Registrar;

Macro to register a MediaNode subclass for runtime creation.

Place this in the .cpp file of each concrete MediaNode subclass. It registers the class at static initialization time so that MediaNode::createNode() can instantiate it by name.
