Hello
Please I am working on this project “https://on24static.akamaized.net/event/25/37/22/4/rt/1/documents/resourceList1598389152860/dstltwebinarmonikav31598389151693.pdf” , in the ADD CUSTUM CODE part, I made the modifications mentioned, I got an error

Hi Sylia,

Please share your configuration files.
Could you please also do export GST_DEBUG=3 and then run the deepstream-app? This will print more Errors and warning that can help to understand the issue.

Hello,
thank you for your reply, so my configuration files: config_infer_primary_peoplenet.txt (1.9 KB) , test5_config_file_src_infer.txt (6.5 KB)

When i do “deepstream-test5-app -c configs/test5_config_file_src_infer.txt GST_DEBUG=3”

deepstream-test5-app -c configs/test5_config_file_src_infer.txt export GST_DEBUG=3

If you disable [sink1] then are you able to run the application?
Also, are you able to run test5 application without analytics plugin?
