问题
As the Google+ Hangouts API has shut down, how can I use the YouTube Live Streaming API to:
Show me that a Hangout I started is broadcasting (I guess because it's broadcasting to YouTube)
Get the join URL for the Hangout on Air (the one that I hand out to others so they can join)?... or at least derive it from something that the API gives me?
