I am trying to show a video on the localhost:8080 of my server. The problem is that I am able to succesfully send video frames as you can see in the following part of the code .
ret, jpg = cv2.imencode('.jpg', frame)
self.wfile.write(bytes("--jpgboundaryn", "utf8"))
self.send_header('Content-Type', 'image/jpeg')
self.send_header('Content-length', len(jpg))
self.end_headers()
self.wfile.write(jpg)
What I want now is also to send additional data in the form of html, for e.g
<ol>
<li>Person: 0</li>
<li>cars: 5</li>
</ol>
To show along on the side of the page. Can anybody point me in the right direction ? Any solutions ?
Thanks.

You generally don't... you could put the jpeg encoded as the "src" of the image element and then the rest of the content as additional data, then count the length of that combined, or, you put the image returned as a separate function with a link to the image and just return the html that indicates to the browser it should then retrieve the image from another link... that or just use a micro-framework such as flask and save yourself a huge amount of frustration...
