How make a service for people want put their stream?

Helle !
I wonder if someone have a solution for me.
I want give to my user the possibility to add their channel (twitch or hitbox) on my site

I mean like something here : http://www.romstation.fr/live
or like that : http://leveldown.fr/
Make a page to know who are connected (on live) and who ore not.
When you click on one stream you arrive on a page you can see the stream
etc..
I think I can do it manually but maybe there are something auto?
Thanks
