Config deepstream parallel consumer topic

Please provide complete information as applicable to your setup.

• Hardware Platform (Jetson / GPU) 4090

• JetPack Version (valid for Jetson only)
• TensorRT Version
• NVIDIA GPU Driver Version (valid for GPU only)
• Issue Type( questions, new requirements, bugs)
• How to reproduce the issue ? (This is for bugs. Including which sample app is using, the configuration files content, the command line used and other details for reproducing)
• Requirement details( This is for new requirement. Including the module name-for which plugin or for which sample application, the function description)

When testing with the sample tritonclient/sample/configs/apps/vehicle_lpr_analytic from this repository, I encountered the following issues:

I have four video sources, which are processed in three branches:

  • Branch 1: Sources 0, 1, 2
  • Branch 2: Sources 1, 2, 3
  • Branch 3: Sources 1, 2, 3

How can I configure config_metamux0.txt, msg-broker-comp-id, and msg-conv-comp-id so that each branch publishes messages to a separate Kafka topic?
I try to use one sink, it can use msg-conv-comp-id to filter but it only works for one topic, when I scale to 3 topics (3 sink type 6), it doesn’t work.

Expected Behavior:

  • Topic 1Branch 1 (Receives messages only from sources 0, 1, 2) (inference result with model in branch 1)
  • Topic 2Branch 2 (Receives messages only from sources 1, 2, 3)
  • Topic 3Branch 3 (Receives messages only from sources 1, 2, 3)

In other words, each topic should receive messages only from the sources within its corresponding branch when inferencing with that branch.

Current NVIDIA-AI-IOT/deepstream_parallel_inference_app: A project demonstrating how to use nvmetamux to run multiple models in parallel. sample does not support multiple msgconv+msgbroker. You can modify the code to support it. The sample is in /opt/nvidia/deepstream/deepstream/sources/apps/apps-common/src/deepstream-yaml/deepstream_sink_yaml.cpp and /opt/nvidia/deepstream/deepstream/sources/apps/apps-common/src/deepstream_sink_bin.c

There is no update from you for a period, assuming this is not an issue anymore. Hence we are closing this topic. If need further support, please open a new one. Thanks
