When going live on YouTube live, you have an option to mark the video as "Public", "Unlisted" or "Private".
When you want to integrate your live stream channel into another website or application, you can easily link to the generic channel page, but only Public video streams are available on that page. (https://www.youtube.com/embed/live_stream?channel=[CHANNELID])
The video ID of every public video stream is also visible on that page when the channel is live.
Is there a way to detect if a channel is live using an unlisted video link and second, to find the ID of that unlisted video link without logging in with the owner Gmail account of that channel?
