How to upload video from the camera to the site?

Question

HTML

There is a camera, you need to add a video to the site. I do not consider third-party services, because over time, access to the Internet will be disconnected from the server. VLC plays video from the camera, but attempts to add to the site are unsuccessful. Browser only fox and chrome. Ideally, it will be if the video is without plugins, that is, it is turned on and working. 1-2 people will be watching.
