Msgbroker - Deepstream

vishakraj · March 21, 2025, 12:27pm

Please provide complete information as applicable to your setup.

• Hardware Platform (Jetson / GPU) - Jetson Development Nano
• DeepStream Version - 6.0.1
• JetPack Version (valid for Jetson only) - 4.6.1
• TensorRT Version - 8.2.1.9
• Issue Type( questions, new requirements, bugs) - questions

Hi, I downloaded the deepstream sdk-6.0.1 from the docker image nvcr.io/nvidia/deepstream-l4t:6.0.1-samples

and tried deepstream_yolo with yoloV8 model

with Redis, where Redis is running in separate docker, and from inside the deepstream sdk container, I can able to send the data through redis

In deepstream_app_config.txt file,


[source0]
enable=1
type=4
uri=rtsp://admin:admin123_@192.168.20.95:554
num-sources=1
gpu-id=0
cudadec-memtype=0

[sink0]
enable=1
type=6
sync=0
gpu-id=0
nvbuf-memory-type=0
msg-conv-payload-type=0
msg-conv-frame-interval=1
new-api=0
msg-broker-proto-lib=/opt/nvidia/deepstream/deepstream-6.0/lib/libhiredis.so
topic=deepstream_topic
msg-broker-conn-str=0.0.0.0;6379

and when starting the inference deepstream-app -c deepstream_app_config.txt

I got this error -

** ERROR: <main:707>: Failed to set pipeline to PAUSED

ERROR from sink_sub_bin_sink1: GStreamer encountered a general supporting library error.

one error on gstreamer and another is from gstnvmsgbroker showing undefined symbol: nvds_msgapi_do_work

could you please share what is this error and how to solve this, thanks

UPDATE:

If I use msg-broker-proto-lib=/opt/nvidia/deepstream/deepstream-6.0/lib/libnvds_redis_proto.so, then this error occurs -

Hello,

I don’t know if it will help.

I can use it using mqtt and my sink is configured like :

[sink4]
enable = 0
type = 6
msg-conv-config = /path/msgconv_config.txt
msg-conv-payload-type = 257
msg-broker-proto-lib = /opt/nvidia/deepstream/deepstream/lib/libnvds_mqtt_proto.so
msg-broker-conn-str = 192.168.8.210;1883;deepstream
msg-conv-msg2p-new-api = 1
msg-conv-frame-interval = 20

Have you tried specifying msg-conv-config config file path ?

vishakraj · March 21, 2025, 5:17pm

Hi, @henri , thanks for writing back

I used this parameter msg-conv-config=dstest5_msgconv_sample_config.txt

and got the same error, and then i tried with export GST_DEBUG=4

then got this error -

** Message: 22:43:19.030: Failed to load file: No such file or directory
Error in creating instance
0:00:00.227224058  2857      0x70ec600 ERROR              nvmsgconv gstnvmsgconv.c:442:gst_nvmsgconv_start:<sink_sub_bin_transform1> unable to create instance

could you please share me what to define in this file = dstest5_msgconv_sample_config.txt, for now i tried with just adding this line in the config file

thanks

vishakraj · March 21, 2025, 5:22pm

Hi, I shared the logs when running this command - deepstream-app -c deepstream_app_config.txt with GST_DEBUG=4 env parameter

log.txt (159.4 KB)

I thought to share this might help to finding the issue, thanks

vishakraj · March 21, 2025, 6:12pm

I have created an emtpy file dstest5_msgconv_sample_config.txt and started the inference deepstream-app -c deepstream_app_config.txt
normally, the inference started but didnt received any output

When given the GST_DEBUG=4 env parameter, got this error -

0:01:25.576676239  3734   0x7efc0b3370 ERROR        rtpjitterbuffer gstrtpjitterbuffer.c:1419:gst_jitter_buffer_sink_parse_caps:<rtpjitterbuffer0> Got caps with wrong payload type (got 50, expected 108)

what this error means, please let me know, thanks

please refer to this topic for deepstream-app can’t send broker data when conv-msg2p-new-api=0.

vishakraj · March 24, 2025, 12:34pm

@fanzh , I modified conv-msg2p-new-api=1, and followed the shared link,

now, the inference is executed successfully, but didnt receive the data

and then I tried with the deepstream-test5 provided sample just changed the model path and tried agian, that time also, the inference is ok, but didnt receive the output in redis

I tried installing the redis dependencies - Gst-nvmsgbroker — DeepStream documentation

then I got the same error -

Hello @vishakraj,

In my case, the msgconv_config.txt file contains :
[sensor0]
enable = 0
type = Camera
id = Camera 1

[sensor1]
enable = 0
type = Camera
id = Camera 2

[sensor2]
enable = 0
type = Camera
id = Camera 3

[sensor3]
enable = 0
type = Camera
id = Camera 4

Which is not used but is added to the data anyway

fanzh · March 26, 2025, 8:00am

nvmsgbroker is opensource. from the log, dlopen can’t open the so. could you share the log of “ldd /opt/nvidia/deepstream/deepstream/lib/libnvds_mqtt_proto.so”?

vishakraj · March 27, 2025, 9:23am

@fanzh , thanks for writing back,

I am using redis, for that this is the output,
Here, libhiredis.so.1.0.0 is not found, is this the issue?, if so, could you please explain how to install that,
please help to find this issue, thanks

vishakraj · March 27, 2025, 9:24am

@henri , thanks for writing back, could you please share what is these sensors, why it is used

fanzh · March 27, 2025, 3:01pm

please refer to \opt\nvidia\deepstream\deepstream\sources\libs\redis_protocol_adaptor\README for how to install libhiredis.

henri · March 28, 2025, 12:58pm

Hey,

I didn’t remember exactly but i think it was for information on the exchanged JSON

fanzh · March 31, 2025, 2:40am

Sorry for the late reply, Is this still an DeepStream issue to support? Thanks!

vishakraj · April 1, 2025, 10:25am

@fanzh, it is worked that the .so file is missing,

@fanzh , @henri , thanks for helping me to solve this issue
