Python Capture Frame without stopping VideoStream

Question

Video Stream

Video Frame Capture

Is there any way to get these both to run simultaneously? Like making the video stream run in the bg or something.

Video Stream:

def gen(camera):
    while True:
        frame = camera.get_frame()
        yield frame


@eel.expose
def video_feed():
    x = VideoCamera()
    y = gen(x)
    for each in y:
        # Convert bytes to base64 encoded str, as we can only pass json to frontend
        blob = base64.b64encode(each)
        blob = blob.decode("utf-8")
        eel.updateImageSrc(blob, 'output')

Frame Capture:

@eel.expose
def CamDetection():
    cap = cv2.VideoCapture(1)
    img_counter = 0

    if True:
        ret, frame = cap.read()
        if not (cap.isOpened()):
            print("failed to grab frame")
            # break
        # cv2.imshow("test", frame)

        # k = cv2.waitKey(1)
        # if k%256 == 27:
        #     # ESC pressed
        #     print("Escape hit, closing...")
        #     break
        # if k%256 == 32:
        #     # SPACE pressed
        img_name = "SKH_frame.png".format(img_counter)
        path = 'F:\Tensorflow\yolov5\webcamimage'
        cv2.imwrite(os.path.join(path, img_name), frame)
        print("{} written!".format(img_name))
        img_counter += 1

    cap.release()
