Hi,
Please set sync=0 to appsink like:

import sys
import cv2

def read_cam():
    cap = cv2.VideoCapture("filesrc location=test.mkv ! matroskademux ! h264parse ! nvv4l2decoder enable-max-performance=1 ! nvvidconv ! video/x-raw, format=(string)BGRx ! videoconvert ! video/x-raw,format=BGR ! appsink sync=0 ")
    if cap.isOpened():
        count = 0;
        while True:
            ret_val, img = cap.read();
            if not ret_val:
                break;
            count = count + 1
            if count % 150 == 0:
                print("decoded frames:", count)
    else:
        print("rtsp open failed")

    cap.release()

if __name__ == '__main__':
    read_cam()

So that you can get decoded buffers immediately. If you need to have interval between the buffer, you can add delay while calling cap.read()
