Deepstream-test5 doesnt receive mqtt message to trigger smart video recording

Accelerated Computing Intelligent Video Analytics DeepStream SDK
1

Please provide complete information as applicable to your setup.

• Hardware Platform (Jetson / GPU) GPU
• DeepStream Version 6.3
• TensorRT Version 8.6.1.6-1+cuda12.0
• NVIDIA GPU Driver Version (valid for GPU only) 535.104.12

• Issue Type( questions, new requirements, bugs) 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)

Problem Statement: When I send an MQTT topic to trigger smart video recording on the deepstream-test5 reference graph, the app works, but no video is recorded. Here’s what I have done for troubleshooting so far:

The original deepstream-test5 reference graph works on my GPU, but it uses the Kafka protocol. I want to use the MQTT protocol instead, so I made the following two changes in the graph:
Proto-lib: Path to ‘libnvds_mqtt_proto.co’
Conn-str: 127.0.0.1;1883
image

The app works without any complaints, but when the MQTT message was published to the Mosquitto broker, no video was recorded. I used the Paho MQTT client to publish messages. I confirmed that the message was sent successfully using the command mosquitto_sub -t test-topic-sr and here is the screenshot from the command::

I have also confirmed that the deepstream-test5 client is connected to the Mosquitto broker using the command journalctl -xefu mosquitto.service which returns:

Next, I used Wireshark to monitor the network connection, and I can see that the deepstream-test5 client sent a subscribe request, as shown below:

So far, everything seems to be working fine. Finally, I enabled the debug flag in the deepstream-test5 “message broker cloud2device receiver” plugin. I expected to see “Received Message Topic: ‘test-topic-sr’ Message: …” printed in the terminal, but it didn’t. My hypothesis is that, for some reason, the MQTT topic was not received by the “message broker cloud2device receiver” plugin, and I wonder why. Any help would be appreciated. Thank you.

Side notes (not sure if they matter): I installed the MQTT protocol adapter following the instruction provided, but later I upgraded Mosquitto to version 2.0.18.

Sorry for late response. We are investigating the problem. Have you tried with deepstream-test5 c/c++ sample? Can the deepstream-test5 c/c++ sample enable the smart recording by the mqtt message?

For DeepStream 6.3, the corresponding Mosquitto version is 1.6.15. Can you use the same version?

Thank you for the reply. I tried Mosquitto 1.6.15 but it didn’t solve the issue. Please find the details below:

  • I installed mosquitto-1.6.15 and copied libmosquitto* to deepstream/lib directory
    I killed the current mosquitto broker and started the new one.
    I have a paho client connected to the broker to publish topic of ‘test-topic-sr’, shown below at 1710452459.
    I have a deepstream app client connected to the broker too to subscribe to that topic, shown blow at 1710452470.
    Since it (deepstream one) subscribed but never received anything, it was kicked out by the broker eventually, shown below at 1710452561.
1710452449: mosquitto version 1.6.15 starting
1710452449: Using default config.
1710452449: Opening ipv4 listen socket on port 1883.
1710452449: Opening ipv6 listen socket on port 1883.
1710452449: mosquitto version 1.6.15 running
1710452449: New connection from 127.0.0.1 on port 1883.
1710452449: New client connected from 127.0.0.1 as mosq-QqrKKjDBhsPMPKCb16 (p2, c1, k60).
1710452459: New connection from 127.0.0.1 on port 1883.
1710452459: New client connected from 127.0.0.1 as python-mqtt-817 (p2, c1, k60).  # paho 
1710452470: New connection from 127.0.0.1 on port 1883.
1710452470: New client connected from 127.0.0.1 as uniqueID (p2, c1, k60).  # deepstream 
1710452561: Client uniqueID has exceeded timeout, disconnecting.

  • The paho client is sending ‘test-topic-sr’ confirmed by calling mosquitto_sub with the output shown below:
    test-topic-sr {"command": "start-recording", "start": "2024-03-14T21:43:19Z", "sensor": {"id": "HWY_20_AND_LOCUST__WBA__4_11_2018_4_59_59_379_AM_UTC-07_00"}}

  • When I run the graph on x84, here is the output from terminal
    I can tell the client sent CONNECT and sent SUBSCRIBE but there is no log showing it received the topic.

  • I’ve also tried deepstream-6.4 (with Ubuntu 22.04, GStreamer 1.20.3, Nvidia driver 535, CUDA 12.2, TensorRT 8.6.1.6, mosquitto 2.0.15, reference_graph-6.4, graph composer-3.1.0) but the issue remained the same
6

Have you tried with deepstream-test5 c/c++ sample? Can the deepstream-test5 c/c++ sample enable the smart recording by the mqtt message?

7

Yeah I did it too but I found more issues. Here are the details:

  • I created rtsp stream from files using the following commands:
cvlc --loop sample_push.mov ":sout=#gather:rtp{sdp=rtsp://:8654/push}" :network-caching=1500 :sout-all :sout-keep
VLC media player 3.0.9.2 Vetinari (revision 3.0.9.2-0-gd4c1aefe4d)
[00005647d8c30620] dummy interface: using the dummy interface module...

  • I confirmed that the uri is valid by playing the stream with vlc.

  • Then I updated the uri in sources_rtsp.csv file, attached here:
    sources_rtsp.txt (127 Bytes)

  • Then I run the deepstream-test5 c/c++ app and I am seeing two issues:

  1. “No supported stream was found”
  2. Client doesn’t even send SUBSCRIBE (it only sends CONNECT)

The full terminal output is attached below:

  • I also tried a different config file: test5_config_file_src_infer.yml. It uses .mp4 files as input so I can focus on the mqtt side. But I am seeing the same issue:
  1. Client doesn’t even send SUBSCRIBE (it only sends CONNECT)

Again the full terminal output is attached below:

What I changed in the config files?

  • sink1: msg-broker-proto-lib, msg-broker-conn-str
  • message-consumer0: proto-lib, conn-str, config-file

Please find the modified config files attached here:
test5_config_file_src_infer.txt (6.6 KB)
test5_dec_infer-resnet_tracker_sgie_tiled_display_int8.txt (8.4 KB)

I also attached the Wireshark log during my test with test5_config_file_src_infer.yml. It is confirmed that the deepstream-test5 client didn’t send SUBSCRIBE and test-topic-sr was not received by any clients.
dstest5_c_start_while_publisher_py_run.txt (835.8 KB)

For vlc issue, please refer to windows - Rtsp h264 missing plugin - Stack Overflow

For the c/c++ deepstream-test5, the subscribe is configured by message-consumer group : DeepStream Reference Application - deepstream-app — DeepStream documentation 6.4 documentation, please enable message-consumer group.

And the smart recording instruction is Smart Video Record — DeepStream documentation 6.4 documentation

The GXF extension is nvidia::deepstream::NvDsMsgRelayReceiver

Thank you again for your reply.

Regarding the vlc issue, I run
GST_DEBUG=3 gst-launch-1.0 rtspsrc location="rtsp://127.0.0.1:8654/push" latency=100 ! rtph264depay ! avdec_h264 ! autovideosink
and I didn’t get any issue. I can view the streaming video just fine though it outputs a few warning. Here is the complete output.

I have decided to no longer investigate the VLC issue. Instead, I have successfully created a deepstream framework that takes a v4l2 camera as input and outputs an RTSP stream effortlessly. Now, I can view the stream on the deepstream-test5 C/C++ application without any problems.

Regarding the second and third points, I have made the necessary corrections. You can find my updated configuration file here:
sources_rtsp.txt (346 Bytes)
test5_dec_infer-resnet_tracker_sgie_tiled_display_int8.txt (8.4 KB)

However, the issue of the test-topic-sr not being received by the client still persists. This issue is evident in the terminal output (pasted below) and can also be seen in Wireshark. The good news is that this issue is not limited to the graph composer but is also present in the C/C++ application.

Next, I will attempt to use NvDsMsgRelayReceiver to address this issue.

Have you tried to run the mosquitto_sub in the same environment of the deepstream-test5-app to make sure the subscribe can be done in the environment?

12

Thank you for your comments. I am able to subscribe to the test-topic-sr by using the command mosquitto_sub -t test-topic-sr . Here is a screenshot of my setup (I also use MQTT Explore to monitor the publishing of topics):

mosquitto_sub+mqtt explorer
mosquitto_sub+mqtt explorer1022×1245 252 KB

However the c/c++ app running at the same time doesn’t log any mqtt topic received in terminal:

Currently the cloud message subscription is supported by Kafka only. Smart Video Record — DeepStream documentation 6.4 documentation

Can you change to Kafka cloud service?

15

The MQTT protocol is currently being used as a standard in our system. As a temporary solution, I can definitely just convert each MQTT topic to a Kafka topic. I am more interested to know if there are any plans to extend the cloud message subscription to include MQTT in the future, given that MQTT is already supported for certain other applications. Thank you.

16

We have added MQTT subcribe message into our roadmap.
