I am new to YouTube live streaming. I am doing it through my application. I have gone through various question/answers on this portal but couldn't find/understand a way to get it.

Is there any way (with YouTube Data API v3) to get live stream tiny URL (something like https://youtu.be/OHi8m4o8XeQ) so that I can share my live stream to my audiences?

I have got a stream key/name (20 character alphanumeric key with four - in between) from YouTube Data API v3, that I will use to stream to YouTube.

I am adding one screenshot for reference. I want the tiny url (something like https://youtu.be/someid) in upper right side.

回答1:

Yes, take your channel url and add /live .

回答2:

YouTube's shortened URL associated to a given video -- identified by its ID VIDEO_ID -- is of form:

https://youtu.be/VIDEO_ID,

where (usually, though not officially documented as such) VIDEO_ID obeys to the following regex pattern:

^[0-9a-zA-Z_-]{11}$.

In the case of live streaming, for to be able to share the shortened URL of one such stream you've created, you should obtain the video ID associated to that stream.

That video ID is to be found as the value of the property id of the LiveBroadcasts resource that is bound to your live stream.
