Segmentation fault (core dumped) when setting msg2p-newapi=true

[xin.liu1]

• Hardware Platform (Jetson)
• DeepStream 7.0
• JetPack 6.0 [L4T 36.3.0]
• Model: NVIDIA Jetson AGX Orin Developer Kit

When setting msg2p-newapi=true and running service-maker/sources/apps/deepstream_test5_app, the app is Segmentation fault (core dumped).

• settings:

  - type: nvmsgconv
    name: msgconv
    properties:
      payload-type: 1
      msg2p-newapi: true

• command:

/opt/nvidia/deepstream/deepstream-7.0/service-maker/sources/apps/deepstream_test5_app/build/deepstream-test5-app -s /ds-config-files/pn26/service-maker/source-list-0_agx.yaml -c /ds-config-files/pn26/service-maker/ds-config-0_agx.yaml -l /ds-config-files/pn26/labels.txt

• errors:

.....
Added stream : sub-batch = 0     seq index = 0   pad index = 0
Segmentation fault (core dumped)

How to resolve?

1. if using msg2p-newapi: false, can the app run well?
2. could you use gdb to get a crash stack? Thanks!

I am not able to reproduce this issue on Orin with DS7.0. Here are the log and configuration files.
log.txt (129.8 KB)
source_list_static.yaml (1.1 KB)
test5_b2.yaml (3.7 KB)

1. if using msg2p-newapi: false, the app runs well。
2. gdb tracking:
   
   
3. It is ok when using source_list_static.yaml with test5_b2.yaml.

1. Thanks for the sharing! could you share your custom configuration files ds-config-0_agx.yaml /ds-config-files/pn26/service-maker/ds-config-0_agx.yaml and /ds-config-files/pn26/labels.txt? Thanks!
2. From the stack, it crashed in generate_dsmeta_message_minimal of opt\nvidia\deepstream\deepstream-7.0\sources\libs\nvmsgconv\deepstream_schema\dsmeta_payload.cpp, which is opensource. you can add log to check which line cause the crash.

1. The configuration files ds-config-0_agx.yaml, source-list-0_agx.yaml and labels.txt are in attachment.
   service-maker-test5-app.zip (2.7 KB)
2. The reason is that privData is NULL in function generate_dsmeta_message_minimal(void privData, void frameMeta)**. If privData is NULL，how to get sensorId in generate_dsmeta_message_minimal?

I will check, then get back to you.

[fanzh]

from your configuration file, you did set config for nvmsgconv. you can add log in opt\nvidia\deepstream\deepstream-7.0\sources\libs\nvmsgconv_audio\nvmsgconv.cpp to check.

Thank you.

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

[xin.liu1]

Thank you, it is solved by setting config for nvmsgconv.
