Different speed of two or more rtsp streams, low frame rate

Thanks for the answer, the first couple of points have already improved performance, but I have a question about the following lines

Continuing the discussion from DeepStream SDK FAQ:

I didn’t quite understand what the minimum pts\maximum pts parameters are. This is the Presentation Time Stamp, - this is a timestamp, that is, in fact, minimum pts is the initial timestamp and maximum pts is the final one. That is, I start the stream and take the very initial label and it will always be the minimum, the maximum label will always be the current one, isn’t it? Or do I need to recalculate to these values within some time interval
