Error when deleting rtsp sources

• Hardware Platform (Jetson / GPU): GPU
• DeepStream Version:
Hi, I modify in deepstream_python_apps to add and delete rtsp input sources. However I meet this error when I delete the rtsp source:

Error: gst-resource-error-quark: Unhandled error (9): gstrtspsrc.c(6161): gst_rtspsrc_send (): /GstPipeline:pipeline0/GstURIDecodeBin:source-bin-01/GstRTSPSrc:source:
Option not supported (551)

But when I use videos as input sources, it works fine. Could you guys help me with the mentioned issue? Thanks in advance !

Can you provide the modified code for us to reproduce the problem? (29.4 KB)

Is this still be an issue? if yes, can you share all the config files you used in the script?

Sorry for late response. Yes, I still have this issue. Here are my config files: dstest_pgie_config.txt (3.8 KB)
dsnvanalytics_tracker_config.txt (1.8 KB)

If you guys need anything else, please just let me know. Thank you very much!
