I want to use the C++ SDK to load the plugin for time event push on the server side. However, when using the plugin to push the pushMetadataPacket object metadata packet, it can succeed, but when pushing the event type, the event does not display on the client side. Even using the sample event plugin does not work. What could be the reason? The software version is the latest one.

  Hello!
  Please specify what exactly do you mean by the event does not display on the client side?

  We would like to understand your expectations. Ideally it would be great to get any sort of the screenshots with what you expect to happen.

  Hi,

  The information provided so far is quite limited. Could you please share the following so we can better understand the issue?

  • Screenshots from the Desktop Client (for  "the event does not display on the client side")
  • The exact manifest file, maybe your device agent as well.
  • A sample of your implementation code

   

  If you are using the “sample stub event plugin” without any modifications, please make sure that:

  • The plugin is installed in the correct folder
  • The Mediaserver has been restarted after installation

   

  We have verified that the sample plugin works properly on Nx Witness / Nx Meta instances. Therefore, it would be helpful if you could provide more detailed information about the issue you are experiencing so that we can investigate further.

   

  Thank you.

  Hello,

  > the event does not display on the client side
  They might be several reasons for that.

  - Event types are not declared in the plugin and the Server knows nothing about them.

  - Event metadata packet sent to the Server is not properly prepared

  - Event processing rule is not configured in the Camera Rules…
  So, as my colleagues said, we need much more details to be able to help you specifically.

  I understand that I haven't configured the event rule on the client side
