Can not run: deepstream-test5 while deepstream-test1/test2/test3/test4 all run OK

  1. Per README file, after make, I issued commands to run the test5 example:

./deepstream-test5-app -c configs/test5_dec_infer-resnet_tracker_sgie_tiled_display_int8.txt -p 0
./deepstream-test5-app -c configs/test5_config_file_src_infer.txt -p 1

But I got following erros:

** ERROR: main:1451: Failed to set pipeline to PAUSED
ERROR from sink_sub_bin_sink2: Could not configure supporting library.
Debug info: gstnvmsgbroker.c(388): legacy_gst_nvmsgbroker_start (): /GstPipeline:pipeline/GstBin:sink_sub_bin2/GstNvMsgBroker:sink_sub_bin_sink2:

ERROR from sink_sub_bin_sink2: GStreamer error: state change failed and some element failed to post a proper error message with the reason for the failure.

Can you please advise how to fix the problem?

Can you attach your config file?


I just uploaded the config file: test5_dec_infer-resnet_tracker_sgie_tiled_display_int8.txt.

After I have looked into that file more, I have found the problem may be related to:

  1. #Provide your msg-broker-conn-str here : missing the important information for topic/host/port

  2. missing the video: uri=rtsp:// and uri=rtsp://

I think that #1 is the main problem.

Hope that you can give me some suggestions.

you need to config kafka server ip and toppic or set enabled = 0 at sink1 group

for your reference

msg-broker-conn-str=ip;9092 // ip for broker running on host
topic=dstest //topic created

For how to setup kafka broker on your machine & create topic(s)

@armcao, thanks. Here is what I have done which can get the test5 to run:

in in the config files: test5_config_file_src_infer.txt and test5_dec_infer-resnet_tracker_sgie_tiled_display_int8.txt, I have added the information:


  1. downloaded the kafka_2.13-2.7.0 and opened the three shells and do:

bin/ config/

bin/ config/

bin/ --create --topic quickstart-events --bootstrap-server localhost:9092

  1. then run the test5

./deepstream-test5-app -c configs/test5_config_file_src_infer.txt -p 1 and
bin/ --topic quickstart-events --from-beginning --bootstrap-server localhost:9092
