+- The user enters :
+    - write the Path of the video with proper video extension and press Enter.
+    - enter the text that you want to mark on the video, press Enter.
+    - give two space seprated coordinate value(location where you want to mark the text).
+    - give 3 space seprated value for text colour(RGB, Ex- 155 168 158) press Enter.
