How can I meke a custom HTML page using web_video_server?

edit

Good evening.

I need to stream two instances of a webcam on the same HTML page.

So far, I am able to:

• Send video from the webcam to the topic /usb_cam/image_raw using the usb_cam package
• Run the web_video_server node
• Access the images using the IP address on a web browser (I don't know how it gets the correct topic to subscribe to)

However, the default HTML page streams only one instance of the webcam.

Therefore, my question is: how (or where) can I make modifications in order to customize this HTML page?

Thank you.
