I have set the msg2p-newapi=1 in the nvmsgconv, so that the payload has to be generated from object meta and frame meta. I’m able to receive the payload at the kafka broker. But I wanted to access the payload after nvmsgconv to manipulate it. I’ve added a probe function at the srcpad of nvmsgconv and attached here for reference. I heard from another topic that the generated payload will be attached as user meta data from frame meta. But I’m unable to access it within my probe function.
Note: I’m using PAYLOAD_CUSTOM. I’ve built the nvmsgconv library with required fields.

Need help in accessing the payload fields within my probe function.

nvmsgconv is opensource, you can add logs to debug.
