I am using Youtube API for creating events from my application in Youtube for Live streaming.That successfully done by the following code.But my requirement:

1) I need to start the live stream from my application interface using youtube API.Is it possible?

2) When I create events from app using youtube API its automatically go to Custom (more encoding options) type.I need to create live streaming events in Quick (using Google+ Hangouts On Air) type.Is it possible?

My code:

<?php

// Call set_include_path() as needed to point to your client library.
require_once 'Google/autoload.php';
require_once 'Google/Client.php';
require_once 'Google/Service/YouTube.php';
session_start();

  • You can create a livestream with a specified start time by using [insert](https://developers.google.com/youtube/v3/live/docs/liveStreams/insert), but I'm not sure if you would consider that "starting a livestream". I believe you can only use Google+ Hangouts On Air if you livestream through your YouTube channel, not the API. – not_a_bot Sep 14 '15 at 18:33
  • I can able to create events using API.Is it possible to enable the google +Hangout option using youtube API? – Kichu Sep 15 '15 at 03:45
  • I think you might be able to do it if you also use the Google+ Hangouts API. See [here](https://developers.google.com/+/hangouts/button) and [here](https://developers.google.com/+/hangouts/api/gapi.hangout.onair). – not_a_bot Sep 15 '15 at 18:14
  • Is it possible to use google+hangout API with youtube live streaming API? – Kichu Sep 16 '15 at 03:58
  • I think you could, but I'm not quite sure how you would do it. Maybe you can get some information from [this](http://stackoverflow.com/a/27916747/4241842) answer. – not_a_bot Sep 16 '15 at 20:32
  • Hey Kichu did my answer help you? Please let me know if you have any other questions. – JAL Dec 27 '15 at 23:31

  1. To start streaming from your application, you need to transition your liveBroadcast from the active to the live state. After binding your liveStream to your liveBroadcast, call transition on your liveBroadcast from testing to live.

  2. To change the quality options, set the cdn.format of your liveStream object:

Valid values for this property are:

  • 1080p
  • 1080p_hfr: This value is for 60 frames per second (fps), or high-frame-rate, -streams.
  • 240p
  • 360p
  • 480p
  • 720p
  • 720p_hfr: This value is for 60 frames per second (fps), or high-frame-rate, streams.

  • Hello @JAL, i'm having issues converting my youtube livestream object from ready to active using the youtube livestream API. I already created a broadcast object and also the livestream object and bind them together with the correct response gotten. But when try to transition it throws an error saying my stream is inactive. Please any assistance would be of great help as my job depends on it. Thank you – Henry9162 Jun 22 '20 at 13:19
