Unable to connect to broker library ( Deepstream-test5-app)

Accelerated Computing Intelligent Video Analytics DeepStream SDK

I am trying to run the DeepStream Test 5 sample app with local RTSP feed coming from an IP camera. I am getting this error.

deepstream-test5-app -c configs/test5_dec_infer-resnet_tracker_sgie_tiled_display_int8.txt

Kafka Client is installed.

sudo apt install librdkafka-dev
librdkafka-dev is already the newest version (0.11.3-1build1).

Path to msg-broker-proto-lib is verified and correct.

arko@arko-jetson-01:$ ls -l /opt/nvidia/deepstream/deepstream-4.0/lib/libnvds_kafka_proto.so
-rw-r--r-- 1 root root 18496 Sep 11 15:45 /opt/nvidia/deepstream/deepstream-4.0/lib/libnvds_kafka_proto.so

So far, I can conclude that its a problem with the finding of Kafka library. But I have no idea, how to proceed the troubleshooting from this point due to my limited knowledge of Deepstream and Gstreamer.

The configuration looks right. I was using the wrong port number for the broker service connection string

msg-broker-conn-str=ec2-11-239-30-175.compute-1.amazonaws.com;9002;DetectionEntry

should be 9092 instead of 9002.

I am also getting the same error when i run this inside docker.

I have installed kafka outside the docker and it’s running properly. Still the above error is coming. Do i need to install kafka inside docker?
Here i am attaching the config file.
