During May 2025, this developer focused on enhancing the stability of the nndeploy/nndeploy repository by addressing a critical naming inconsistency in the global Create/Decode/Encode Node Function Maps. Using C++ and Markdown, they refactored the codebase to correct map names and updated all related shared pointer references, thereby eliminating potential runtime errors during codec node creation and registration. Their work involved careful typo correction and code refactoring, which improved the reliability of the decoding and encoding pipeline. Although no new features were added, the changes reduced future regression risk and supported safer, more maintainable deployment and enhancement of the system.
