 ## Conclusion
 ESP FOURCC provides a unified and efficient way to identify multimedia data formats across embedded systems, addressing common challenges such as inconsistent identifiers, high conversion overhead, and debugging complexity. By leveraging the compact and expressive FOURCC encoding method, the ESP-GMF framework ensures standardized communication between modules while optimizing for performance and maintainability.
 
-Through clear macro definitions, helper utilities, and an extensible set of format codes, ESP FOURCC enables developers to build scalable and interoperable multimedia applications with ease. Whether working with audio, video, images, or pixel data, ESP FOURCC lays a solid foundation for future-proof, modular embedded multimedia development.
