Task: I want to view video from a camera connected to my PC from a browser.
I have a webcam that is connected to a PC. There is a node.js server on heroku.com.
Questions:
1. How to get a stream from a camera and send it to the server?
2. What programming language is better to use to receive a video stream (taking into account that OS==windows is installed on the PC)?
3. How to receive a stream on the server and play it in the browser? (server on nodejs - it will start up with it or something else is needed)
I don’t understand much in programming. With the help of this task, I want to practice and realize my Wishlist)

Thank you.
