Checkout PlaylistItems, it returns all the videos from your playlist.
"A playlistItem resource identifies another resource, such as a video,
that is included in a playlist. In addition, the playlistItem resource
contains details about the included resource that pertain specifically
to how that resource is used in that playlist."
For Java code samples, checkout the Official Youtube api-samples/java for code reference.

How to use the Google+ Hangouts API to get the Hangout On Air YouTube Live Video Embed URL?

I created an google+ hangout app.
now i want to get a youtube LIVE video embeded url to display.
i tried below Js in my browser console after starting broadcast
gapi.hangout.onair.getYouTubeLiveId(); <br/>
but i am getting 'null' as the result.
i tried gapi.hangout.onair.isBroadcasting();
but i am getting 'false' as the output in chrome browser console.
i tried gapi.hangout.onair.isOnAirHangout();
but it got 'false' as the output.
can anyone tell me the reason?
According to API documentation, getYouTubeLiveId() returns the YouTube Live ID for the Hangout On Air. Returns null if the ID is not available or the Hangout is not a broadcast hangout. Also, off-hand, I'm not sure it will provide the ID to a non-HOST. It's worth it to try as both Host of HoA and Participant and see if there's a difference.
I'm happy to test with you if you like.
