Communication with secondary app on Jetson

Please provide complete information as applicable to your setup.

• Hardware Platform (Jetson / GPU) Jetson AGX orin

This is more of a general question. What we would like to do is to run a Deepstream application (c++) in parallel with a secondary python application. The secondary application will use the generated data from the Deepstream application (object id, object bbox position, class id, etc). Currently we are able to run the Deepstream test 4 example (AMQP) with rabbitmq. We can then access the data by connecting to the server with the secondary application and extract the information since it is in json format. My question is : Would it be possible to simply send the data in JSON format via a simple socket to the secondary app via the nvmsgbroker (without a server) ? I think it supports payload in JSON format but there is no example of how to implement this and it is not clear on how to achieve this. What would be the advantages of using RabbitMQ instead of a simple socket in that case ?
Thanks for your help

yes, but there is no ready sample, nvmsgbroker is opensource, you can modify code to implement, the path: opt\nvidia\deepstream\deepstream\sources\gst-plugins\gst-nvmsgbroker\gstnvmsgbroker.cpp

There is no update from you for a period, assuming this is not an issue any more.
