Hi,
I am using the Python DeepStream SDK to create a pipeline that utilizes 20 RTSP input streams from IP cameras. My pipeline is able to add or delete sources dynamically. If I run my pipeline with a small number of cameras, it works as expected. However, if I increase the number of inputs to above 10, I encounter the following error after some runtime.

 2024-04-17 02:15:23    ERROR - Error: gst-resource-error-quark: Could not read from resource. (9): gstrtspsrc.c(5560): gst_rtspsrc_loop_interleaved (): /GstPipeline:pipeline0/GstBin:source-bin-3/GstURIDecodeBin:uri-decode-bin/GstRTSPSrc:source:
Could not receive message. (Parse error)

I have two questions:

1. What is the root cause of this issue?
2. Is there a way to delete and re-add the erroneous input or reconnect to that source?

Thanks a lot.

1. this is Gstreamer error log, which mean rtsp abnormal connection, the client can’t receive message from server.
2. please refer to this topic for rtsp reconenction in python.
