NvmsgBroker

NvmsgBroker not working in deepstreamtest-4

ERROR from element nvmsg-broker: Could not initialize supporting library.
Error details: gstnvmsgbroker.c(296): gst_nvmsgbroker_start (): /GstPipeline:dstest4-pipeline/GstNvMsgBroker:nvmsg-broker:
unable to open shared library
Returned, stopping playback
Deleting pipeline

could you help to set GST_DEBUG=4 and rerun the sample to get more details?
Also pls provide the DS version and platform which you used.

I have the same problem. Where do I set the GST_DEBUG?

Did you get your problem solved?

unable to open shared library
It seems it can’t find someone lib. Can you check which lib?

It seems like msgnvbroker is the lib

libnvdsgst_msgbroker.so is in

/usr/lib/aarch64-linux-gnu/gstreamer-1.0 or
/usr/lib/x86_64-linux-gnu/gstreamer-1.0

You can also build your own libnvdsgst_msgbroker.so in sources/gst-plugins/gst-nvmsgbroker

The command line is like this:
$ deepstream-test4-app -i -p --conn-str= -s <0/1>

Did you set “Proto adaptor library” ?

Yes, this works for me. Thank you Chris! I am now trying to add the whole frame data inside the meta data. Inside function “osd_sink_pad_buffer_probe”, the frame information is already in the format of metadata. Do you have any suggestions on how I can add the whole frame information into metadata?

Hi ChrisDing / qsu,

I am trying to run deepstream-test4-app using rabbitmq message broker. I have followed all the instructions in Readme and the advise given above. I have also ensured that I have a local RabbitMQ server running on localhost. However, I am not able to get the application to work.

Following is the error I am constantly getting:

Using winsys: x11 
Running...
ERROR from element nvmsg-broker: Could not configure supporting library.
Error details: /dvs/git/dirty/git-master_linux/deepstream/sdk/src/gst-plugins/gst-nvmsgbroker/gstnvmsgbroker.c(332): gst_nvmsgbroker_start (): /GstPipeline:dstest4-pipeline/GstNvMsgBroker:nvmsg-broker:
unable to connect to broker library
Returned, stopping playback
Deleting pipeline

I have not edited “cfg_amqp.txt”. It is as follows:

[message-broker]
password = guest
#optional
hostname = localhost
username = guest
port = 5672
exchange = amq.topic
topic = topicname

My command-line looks like the following:

./deepstream-test4-app -i /home/jetson/deepstream_sdk_v4.0_jetson/samples/streams/sample_720p.h264 -p /opt/nvidia/deepstream/deepstream-4.0/lib/libnvds_amqp_proto.so --conn-str="localhost;5672;guest" -s 0

When I am trying out the basic send/receive tutorial from https://github.com/rabbitmq/rabbitmq-tutorials, it seems to work.

Kindly let me know where I am going wrong. Please help me out.

Thanks.

deepstream-test4-app -i ../../../../samples/streams/sample_720p.h264 -p /opt/nvidia/deepstream/deepstream-4.0/lib/libnvds_azure_proto.so -c cfg_azure.txt -s 0 --no-display

I am trying to run deepstream-test4 but it throws the below error:

if you carefully see line 9, the path /dvs/git/dirty/git-master_linux/deepstream/sdk/src/gst-plugins/gst-nvmsgbroker/

doesn’t exists, how to fix this.

Hi, I have the same issue. Did you manage to solve the problem?

Not yet, i have been trying to run deepstream-test4-app, from so many days there isn’t any proper explaination. I followed all the instructions on provided Readme, But that doesn’t seems to be helpful.
Is there any way to test message broker locally i.e., without having an Azure Iot account. I tried with rabbit mqtt local server but it wasn’t working.
I have tried everything from my side but still i am having issues.

:( Today in my despair, I have published this post clearly detailing the steps I am following.


I hope someone can guide us. Regards

I had the same error until I released I had not compiled and installed the client side of the rabbitmq C lib for the test4 app to use.

See the README in the test4 app.

Which points you to:
