I'm not sure if this is the right place for this, but:

This is more computer programming.

I can do the full process of a You Tube site.

However, I want to live stream video from a webcam over the internet.

This must all be browser based.

Person 1 logs in on the internet, connects webcam and starts broadcasting.

Person 2 can then watch this from a browser anywhere in world.

There is a service called videowhisper.com (Live Streaming product) which will do this but it is very closed that I can't edit any of the fash files - must use their style etc.

I only really need the bit where flash captures the web cam video and then sends to a rtmp server (I have rtmp server and I have a flash player for each viewer to play it)

Remember all must be in a browser, not for people to download some PC software.
