I have a site where registered users can launch Hangouts on Air from a page. I need to be able to embed the video into the page for other users to view. However, the button API doesn't seem to callback with anything useful. Is there any way I can do this? I don't want to have to write my own Hangouts app because I can't have the viewers require a Google account to view it.
Sorry for answering it late You are on the right path,
To get the youtube id back in your application soon after the hangout is broadcasted, you have to :-
