Setting up a live internet video feed from a home webcam

I’m trying to help someone set up a 24/7 broadcast of a live video feed, from his home webcam,
that can be viewed in a video player (specifically JW Player) on his personal website.

There won’t be more than just a few people at a time viewing the live feed on his website.

JW Player supports live streams, and I think I can figure out what needs to be done with that.
But how can this be set up from his home? Is there a program he can download on his PC that
will assign his webcam’s feed an IP address of sort?

If someone could just point me in the right direction here, it would be much appreciated. Thanks.
