Hi there, I am using the deepstream lpr app with 5 RTSP stream. If there is one RTSP was disconnected, the application tends to exits. How can i remove the stream without exiting the app. Besides, thinking about adding the stream, what if i have a 6th stream to be added while the application is running, is it possible for the application to add the stream and start inference without restarting?

Please refer to the sample deepstream_reference_apps/runtime_source_add_delete at master · NVIDIA-AI-IOT/deepstream_reference_apps (github.com)

I have seen this before, but this is only adding for the same RTSP stream. May i know are there any ways for the application to add a different RTSP stream.

You need to create new source element with the new RTSP stream, and the following steps(connect pads, change state,…) are the same as in the sample.
