Does v6+ still support Video Source Plug in?

I am interested in developing a plug in that connects to a 3rd party NVR streams live video and allows the NVRs local footage to be accessed by NX native playback and export functions. Is this possible on latest release and if so what are the best plugin samples to start from. My initial review looks like video source and image library. I have stubbed out the axis camera sample but i haven't as yet been able to get it to load successfully. I don't seem to be able to get past - ERROR: Cannot load library ... The specified procedure could not be found.

I read previous old posts that say it was possible but want to check if that's still the case, any guidance or support would be very much appreciated

  Hi jack stubbs,

  Thanks for your question. Yes, it is still available and supported by all the version of Nx mediaserver.
  We may suggest you start with Nx Gen6, i.e. the latest 6.1.0 beta and the video source SDK.

  Regarding to the error, the information is quite limited, so unfortunately there is no conclusion could be made, but I suggest you can go with the latest version and if you still have the issue, likely we will try to look into it later.

  * Gen6, 6.1.0 : https://meta.nxvms.com/download/other/betas

  *Ubuntu x64 - server_plugin_sdk_samples metavms-server_plugin_sdk_samples-6.1.0.41083-linux_x64.zip
  *Windows x64 - server_plugin_sdk_samples metavms-server_plugin_sdk_samples-6.1.0.41083-windows_x64.zip

  Thanks for your response, for a little more context I have compiled the plugin based around minimal code to verify build setup etc. I’m failing at the first hurdle. My code is completely minimal but does declare createNXPluginInstance properly, does the server need anything else to load the video source plugin? I see in the logs that the consideration is made to load the plug in and assume all linked dependencies are available.

  I’m currently on 6.0.3 is there merit in moving to the newer versions then?

  Hello Jack Stubbs ,

  Sorry for missing this thread.

  Could you expand on the issue you're dealing with please?

  1. Were you able to build one of the code samples provided with the SDK? I.e. using build_samples scripts.
  2. If so, please see the intrerfaces implementation there. Please try to implement your minimal code patch over the sample plugin(metadata_sdk/samples/sample_analytics_plugin). Whether you still see the build errors, please provide us with the errors output. My colleagues might follow up with you over the zendesk ticket undisclosed to public to troubleshoot.
  3. Any additional technical details are always appreciated.
