Can I change or switch video source at run time using deepstream

Hi,

I am using deepstream4.0 on Xavier platform.
Can I add a video source or reduced the no of sources when my deepstream pipeline is already running?

pipeline:
nvstreammux -> nvinfer -> nvtracker -> customPlugin -> nvvidconv -> nvdsosd -> nvmultistreamtiler -> nveglglessink

Hi,
I am also looking for the same. I have multiple source of rtsp streams, but i want to round-robin the rtsp source each at a time. (ie)can i iterate the rtsp uri in deepstream?
