How to set up a live video broadcast from a specific location?

Question

Video

Good evening (day, night, morning)!
There is a certain conditional place of mass visits. There is an official website for this place.
It is necessary to do something like a "teleconference", online video broadcast from this place through a webcam or a regular one, but not fancy on the site.
Broadcast does not have to be in super cool quality with super cool functionality. Everything is at the level of "transmitting a picture with sound to a site from a webcam, quickly and easily."
Can you tell me the easiest way to implement this? Is it possible to do this for free? Will it be necessary to connect third-party services? I am not interested in installing cameras, but in the algorithm itself for transferring data to the site. Through what? How? How difficult?

In a primitive way, you will need nginx + nginx_rtmp + ffmpeg + flowplayer.
It's all free. The main resource is traffic. Calculate about a megabit per viewer.

I can add from myself - I personally raised it, everything works fine - cross-browser and on all platforms.
