title: ESP32-CAM stream in OpenCV Python
body: <p>I am using AI Thinker ESP32-CAM with stream url <code>http://192.168.8.100:81/stream</code>.
  I have tried this and other techniques but nothing worked for me</p>
  
  <pre><code>import numpy as np
  
  cap = cv2.VideoCapture("rtsp://192.168.8.100:81/stream")
  
  while(True):
      ret, frame = cap.read()
      cv2.imshow('frame',frame)
      if cv2.waitKey(1) &amp; 0xFF == ord('q'):
          break
  
  cap.release()
  cv2.destroyAllWindows()
  </code></pre>
  
  <p>I've tried <code>http</code> as well instead of <code>rstp</code> but no results at all</p>
