Can you get output from below command line ?

 readelf -W -s /opt/nvidia/deepstream/deepstream/lib/libnvdsgst_helper.so|grep gst_nvevent_new_stream_start

I think your deepstream is missing some shared libraries.

Can you upgrade to version 6.3? It’s the latest version, a lot of bugs have been fixed.

96: 00000000000046b0 89 FUNC GLOBAL DEFAULT 14 gst_nvevent_new_stream_start

Can I download something to fix it so I can buy some time and upgrade to 6.3?

There is no update from you for a period, assuming this is not an issue anymore. Hence we are closing this topic. If need further support, please open a new one. Thanks

try install.sh in /opt/nvidia/deepstream/deepstream . Or you can try docker.
