Video frame issues with Theta V

Hi,

I want to transfer Theta V camera frames to computer, so I connected them via USB and tried to show frames using python.

I used live-streaming mode on Theta V to transfer frames.

Here is my code:

import cv2

def imgShow():
    cap = cv2.VideoCapture(0)
    tm = cv2.TickMeter()
    tm.start()

    count = 0
    max_count = 10
    fps = 0
    while 1:

        ret, frame = cap.read()

        if count == max_count:
            tm.stop()
            fps = max_count / tm.getTimeSec()
            tm.reset()
            tm.start()
            count = 0

        cv2.putText(frame, 'FPS: {:.2f}'.format(fps),
                    (10, 30), cv2.FONT_HERSHEY_SIMPLEX, 1.0, (0, 255, 0), thickness=2)
        cv2.imshow("teste", frame)
        count += 1

        if cv2.waitKey(1) & 0xFF == ord('q'):
            break

def main():
    imgShow()


if __name__ == "__main__":
    main()

Camera frames were displayed correctly on the computer, but the frame rate was only about 10 fps.

I know Theta V is an older camera, but is it not possible to get 30 fps frames? Or are there any solutions?

Any help would be greatly appreciated.
