title: display video on python without opencv?
body: <p>I am using openCv for making video processing. What I do is reading a video frame by frame, then applying some processing on each frame and then displaying the new modified frame. My code looks like that :</p>
  
  <pre><code>video_capture = cv2.VideoCapture('video.mp4')
  
  
  while True:
  # Capture frame-by-frame
    ret, frame = video_capture.read()
  
  # Applying some processing to frame
                   .
                   .
                   .
  # Displaying the new frame with processing
    img=cv2.imshow('title', frame)
  
    if cv2.waitKey(1) &amp; 0xFF == ord('q'):
        break
  </code></pre>
  
  <p>This way I can display instantaneously the processed video. The problem is the display is lagging much due to the presence of the 'waitkey'. Is there another way for display images in real time to form a video, but with another module than cv2?</p>
  
  <p>Thank you</p>
