How to broadcast from a webcam to a stream?

Question

Video broadcast

There is a machine to which N cameras are connected, is there any way to send their output to the network in order to catch it in the browser using the same HTML5 (or other available alternatives)?
I tried Yawcam - the goal was achieved by accessing the file at a rate of 30 requests per second, but for several cameras a sufficiently large load on the processor comes out + also depends on the number of clients.
VLC also solved this issue, but with long delays - from 5 seconds.
