title: Write text in streaming video in node js
body: <p>I'm looking for some solution to stream recorded videos safely to stop privacy making a streaming like website for a school for streaming I'm following this tutorial <a href="https://github.com/Abdisalan/blog-code-examples/tree/master/http-video-stream" rel="nofollow noreferrer">https://github.com/Abdisalan/blog-code-examples/tree/master/http-video-stream</a> which works fine for me but can someone download video with this technique? if yes then any way or keywords which i can search for if user can't download video then stop the screen recording how can I print the particular text on random places in entirely video which can be the username or email of the student.
  Thanks a lot.</p>
