Using the DeepStream framework with nvstreammux enabled (new mode),
when dynamically adding a video stream via nvmultiurisrcbin,
it takes about 7 seconds from calling the add interface to detecting the first frame in the pad probe.
The same behavior can be observed in the example mentioned in the following post through the logs:

What kind of sources did you test? Local video file, rtsp stream or others? How did you measure the time " from calling the add interface to detecting the first frame in the pad probe ."?

I used an RTSP stream as the input source. The time was measured from when the add interface was called until the first frame was detected in the pad probe.

What is the IDR frame interval of your RTSP stream?
