In journalctl -xe, I spotted:

 

Oct 14 03:50:35 xav1 mediaserver[4214]: [plugin] Created axis_analytics_plugin[0x7f48068470]
Oct 14 03:50:35 xav1 mediaserver[4214]: [plugin] Created dahua_analytics_plugin[0x7f48064a50]

Oct 14 03:50:35 xav1 mediaserver[4214]: [plugin] Created vca_analytics_plugin[0x7f48e14840]

 

I guess unnamed_lib_context is my new plugin.

How to turn this template name into my own name (ex. my_app_plugin) ?

 

Here's my Engine manifest string:

R"json(
{
    "id": "com.myapp.nxplugin",
    "name": "My App plugin",
    "description": "A plugin for AI modules developed by us",
    "version": "0.5",
    "vendor": "AI Champion"
})json"

  Can you please check how NX_PLUGIN_API macro is defined in your plugin?

  Here are places containing NX_PLUGIN_API word:

   

  In CMakeLists.txt:

  target_compile_definitions(nx_sdk PRIVATE NX_PLUGIN_API="")
  
  

  target_compile_definitions(df_plugin
      PRIVATE NX_PLUGIN_API=${API_EXPORT_MACRO}
      INTERFACE NX_PLUGIN_API=${API_IMPORT_MACRO} #< Needed to link unit tests exe to plugin lib.
  )

   

  In Engine.cpp:

  extern "C" NX_PLUGIN_API nx::sdk::IPlugin* createNxPlugin() {
  
    return new nx::sdk::analytics::Plugin(
        kPluginManifest,
        [](nx::sdk::analytics::Plugin* plugin)
        {
          return new DFNxEngine(plugin);
        });
  }

  Most of the code sniplets are copied from stub_analytics_plugin sample

  In addition to previous comments:

   

  if(WIN32)
      set(API_IMPORT_MACRO "__declspec(dllimport)")
      set(API_EXPORT_MACRO "__declspec(dllexport)")
  else()
      set(API_IMPORT_MACRO "")
      set(API_EXPORT_MACRO "__attribute__((visibility(\"default\")))")
  endif()

  Hi Plain Wu,

  I suggest that you check the following:

   

  1. The file lib_context.cpp from the SDK is compiled as part of your plugin project.
  
  2. The following function defined in your plugin is actually being called by the Server (e.g. set a breakpoint):

  lib_contrext.cpp: /*extern "C"*/ ILibContext* nxLibContext()

  For details about how lib_context mechanism works, please see the comments in `lib_context.h`.

  Great! this works!

   

  I added instance.setName() in LibContext& libContext();

   

  Thank you!
