And it fails to run.

The pipeline you posted can work well in my Jetson board.

I have the same problem, with DS 4.

Actually, the pipeline I posted did work, however, when I add the MQTT pipeline in, it does not work:

We are using AWS MQTT broker, if that’s not available to you, could you provide a sample Kafka or other MQTT broker command line?

Deepstream supports Azure MQTT Protocol with nvmsgbroker. The deepstream sample is in /opt/nvidia/deepstream/deepstream-5.0/sources/apps/sample_apps/deepstream-test4. Please read the README file under the folder.

https://docs.nvidia.com/metropolis/deepstream/dev-guide/text/DS_plugin_gst-nvmsgbroker.html#

According to the docs, we can put own our library via the
‘proto-lib=’ parameter which is what we are doing. We have build our own library for AWS which works fine with testapp4, but not in this case. @Fiona.Chen are you saying Deepstream nvmsgbrooker pipeline plugin ONLY supports Azure and the proto-lib functionality is broken?

No. nvmsgbroker can support customized protocol adapter.Gst-nvmsgbroker — DeepStream 5.1 Release documentation

Since your new proto lib can work with deepstream-test4, there is no problem with the gst-launch-1.0 pipeline. The only difference between deepstream-test4 and the gst-launch pipeline is that deepstream-test4 use “osd_sink_pad_buffer_probe” probe function to generate NvDsEventMsgMetawhich is the message can be send to cloud but the gst-launch pipeline can not. The nvmsgconv must be used in a gstreamer application but not gst-launch pipeline.
