There is a warning when I send msg through msgbroker, and I can not recive msg.

I try to modify ‘max-size-buffers’ but the warning also exist.

The gst_nvmsgbroker_render() function send message, but I find the deepstream-app did not call this function.

1. are you testing deepstream-app? please refer to “2) I see the following WARNING:” of opt\nvidia\deepstream\deepstream-7.0\sources\apps\sample_apps\deepstream-test5\README for how to modify max-size-buffers.could you share a whole log and deepstream-app configuration file?
2. if you add log in gst_nvmsgbroker_render, will the log be printed? especially you need to rebuild and replace the so after modifying the code.

1. How to set ‘max-size-buffers’? I set it to 4000 or 5, but the issue did not disappear.
2. No, There is no print log when I add it to gst_nvmsgbroker_render() function.
   
   

The “1111111” did not appear in log.

I found gst_nvmsgconv_transform_ip() function in gst-nvmsgconv only call once when deepstream-app start.

1. if you are using kafka, you can use this tool /opt/nvidia/deepstream/deepstream/sources/libs/kafka_protocol_adaptor to test kafka sending first.
2. if gst_nvmsgbroker_render is not entered, it is abnormal because all data will go to the last element sink. you can execute “export GST_DEBUG=3,nvmsgbroker:6”, then run the app. there will be nvmsgbroker’s log. for exmaple,

 0x7fa310001110 DEBUG            nvmsgbroker gstnvmsgbroker.cpp:513:legacy_gst_nvmsgbroker_render:<nvmsg-broker> render

3. did you modify the deeepstram-app code? without code modifications, will the issue can be reproduced? if so, could you share a whole log? wondering if there is any abnormal log.

@huihui308

I found gst_nvmsgconv_transform_ip() function in gst-nvmsgconv only call once when deepstream-app start.

The code run well on one device with ubuntu18.04, but this issue appear when I change a device but the system is also ubuntu18.04.

The log is as following.
log.txt (16.1 KB)

[fanzh]

1. what kind of broker are you using? kafka? is create_jpegsink_bin your custom code? to narrow down the issue, without code modifications, will the issue can be reproduced?
2. from the log, gst_nvmsgconv_transform_ip was not called. you can add log in gst_nvmsgconv_transform_ip_video_audio to check if the app hung in this function.

OK, I have solved this issue.
I send redis message in nvmsgconv plugin, but the redis server did not run well, So deepstream-app stuck in nvmsgconv plugin.
Thank you for reply.
