Hello, can MarkersPlugin be used to drag and drop the marked plugin to change its position?

Hi dev team, I want to display src from flask src: Normally, a flask video feed will be like this:

To establish the flask/opencv connection you do something like the following. In your flask you setup a function:

def webcam():
    camera = cv2.VideoCapture(0)

    while True:
        success, frame = camera.read()
        if success:

            ret, buffer = cv2.imencode('.jpg', frame)
            frame = buffer.tobytes()
            yield (b'--frame\r\n'
                   b'Content-Type: image/jpeg\r\n\r\n' + frame + b'\r\n')
        else:
            camera.release()

And you setup an API endpoint

@app.route('/webcam')
def webcam_display():
    return Response(webcam(), mimetype='multipart/x-mixed-replace; 
                    boundary=frame')

And in your frontend to display the stream, you just call the api endpoint in the image source.

  <img src={url} alt="webcam" />

If there are multiple cameras you could maybe set up multiple endpoints and then via frontend connect to whatever endpoint you need via state at the time.

Then, how do I feed this kind of src?
