Display date and time in videos

It sometimes becomes necessary to display date and time on videos when we are processing videos of live feed or videos which are of a large duration. Time and date will be helpful to know and analyze any anomaly detected in the video with reference to its time and date. To display date and time on videos we do the following.

# Import libraries
import numpy
import cv2
import datetime
  
# open the video
vid = cv2.VideoCapture('sample.mp4')
  
# Process untill end.
while(vid.isOpened()):
    ret, frame = vid.read()
  
    if ret:
        # describe the type of 
        # font you want to display
        font = cv2.FONT_HERSHEY_SCRIPT_COMPLEX
  
        # Get date and time and 
        # save it inside a variable
        dt = str(datetime.datetime.now())
  
        # put the dt variable over the
        # video frame
        frame = cv2.putText(frame, dt,
                            (10, 100),
                            font, 1,
                            (210, 155, 155), 
                            4, cv2.LINE_8)
          
        # show the video
        cv2.imshow('frame', frame)
  
        key = cv2.waitKey(1)
          
        # define the key to
        # close the window
        if key == 'q' or key == 27:
            break
    else:
          
        break
          
          
# release the vid object
vid.release()
  
# close all the opened windows.
cv2.destroyAllWindows()
