Request for Detailed Guidance on Developing and Deploying a Plugin for Nx Witness Client on Windows

Dear Network Optix Support Team,

I am currently working on developing a custom plugin for the Nx Witness Client (version 6.1.0) on Windows.
Our goal is to build a simple plugin that displays a custom “Welcome” screen or processes video metadata using the Nx Metadata SDK.

To proceed correctly, I would like to request official and detailed guidance on the following topics:

1. Development Environment Setup
   • What are the required tools, SDK versions, and dependencies for developing Nx Witness Client plugins on Windows?
     (e.g., Visual Studio version, CMake, Boost, OpenVINO, Metadata SDK, etc.)
   • Are there specific environment variables or paths that must be configured for Nx Metadata SDK or OpenVINO?
2. Plugin Build Process
   • Step-by-step instructions for building the plugin using Visual Studio or CMake on Windows.
   • How to correctly link and configure dependencies such as the Metadata SDK, Boost, and OpenVINO.
   • How to properly set metadataSdkDir, InferenceEngine_DIR, and other required variables during build.
3. Plugin Deployment
   • How to install and register the plugin so that it appears and runs in Nx Witness Client.
   • Folder structure and naming conventions for placing the compiled .dll plugin files.
   • Any configuration files or manifest files required for plugin recognition by Nx Witness.
4. Plugin Debugging and Logs
   • How to view plugin logs or debug output from the Nx Witness Client.
   • Best practices for troubleshooting issues when the plugin does not load or fails to initialize.
5. Compatibility Notes
   • Which versions of OpenVINO are officially supported for plugin development (e.g., OpenVINO 2021.4 LTS vs. newer releases like 2025.3).
   • Any known compatibility issues between newer OpenVINO versions and Nx Witness SDKs.

If available, please provide:

• Official documentation or developer guides for plugin development on Windows.
• Example projects or reference implementations that work with Nx Witness Client 6.1.0.

Thank you very much for your assistance.
I look forward to your detailed response to ensure proper setup and deployment of our custom Nx Witness plugin.
Thanks!
