Enhance Codec Implementation to Support Singleton Pattern

[jchrys]

Background

In the current state of the project, the Codec implementation is not designed as a singleton, which means that each time a new instance is required, a new object is created. This approach may lead to increased memory usage and unnecessary object creation overhead, especially in situations where a single instance of the Codec is sufficient for the entire application.

Proposal

To address this issue, it is recommended to modify the Codec implementation to follow the singleton pattern. This would ensure that only one instance of the Codec exists throughout the application's lifecycle, providing benefits such as reduced memory consumption and improved performance.
