[Python] How to read ip camera(rtsp) frames with python smoothly and without and delay and...

I am working on a client project to count cement bags on a trolley. The setup is as follows: Cement bags are placed on a trolley, which is then loaded into a wagon. During this process, I need to count how many bags are loaded. For this task, I am using the YOLOv11n-seg model.

To capture the video feed, I am reading an IP camera stream via an RTSP link. However, during detection and counting, the frames often lag or delay, disrupting smooth processing. Initially, I tried OpenCV for camera streaming, but it had performance issues. Then, I switched to GStreamer, but the problem persisted. Finally, I attempted FFmpeg, but it still didn’t resolve the latency issue

"As of now, I've tried multiple approaches to read an IP camera's RTSP stream, but I still face delays and lagging issues. I've used GStreamer, FFmpeg packages, and OpenCV, but none of them provide smooth camera reading. On the other hand, VLC and other media players stream very smoothly. Why is this happening?"
