Streaming live video to a web site

I've received a request asking if it's possible to开发者_Go百科 stream live video to a web site. The person requesting this has a notebook running MacOS, a professional camera that can be connected up using Firewire and a web site with PHP/MySQL.

What solutions exist to stream the video out on the Internet and, if practical, what would be necessary to display the live video on a web page in programming terms ?

Edit: There are these topics on stackoverflow but I'm not sure if they're relevant:

Live Video Streaming with PHP

How do I stream Live Video

There is also this page over at apple.com:

top of my head, VLC Media Player. It has the ability to stream Live Video from a given capture device. There is a how to guide here.

One shortcoming I noticed is the end user must have VLC installed as well. But I am sure there is a way around it with enough research.

After some searching, it appears that the solution might be as simple as entering some html markup to point a player to the streaming server. I'm still unsure of this, however, and some tests will need to be carried out.
