sahusoftcom/youtube-livestream-api:

PHP (Laravel) Package for Google / YouTube API of Video Live Streaming with Google Auth

Installation :

composer require sahusoftcom/youtube-livestream-api

Add Service provider to config/app.php provider's array:

SahusoftCom\YoutubeApi\LiveStreamApiServiceProvider::class

Execute the following command to get the configurations:

php artisan vendor:publish --tag='youtube-config'

Steps to create your google oauth credentials:

1. Goto https://console.developers.google.com
2. Login with your credentials & then create a new project.
3. Enable the following features while creating key
   • Youtube Data API
   • Youtube Analytics API
   • Youtube Reporting API
4. Then create API key from credentials tab.
5. Then in OAuth Consent Screen enter the product name(your site name).
6. create credentials > select OAuth Client ID. (here you will get client_id and client_secret)
7. Then in the Authorized Javascript Origins section add you site url.
8. In the Authorized Redirect URLs section add add a url which you want the auth code to return(redirect_url)
9. You will get values (to be exact - client_id, client_secret, api_key, redirect_url)
10. Now add these values - client_id, client_secret, api_key and redirect_url in the env file.

Setting Up the App:

Authentication and Authorization:

<?php
namespace Your\App\NameSpace;

use  SahusoftCom\YoutubeApi\AuthService;	// Add Code to call the api class

$authServiceObject = new AuthService();

# Replace the identifier with a unqiue identifier for account or channel
$authUrl = $authServiceObject->getLoginUrl('email','identifier');

• Now you will get $authUrl, upon redirecting to the same will ask permissions and authorization access to the required channel.
• Upon submitting the requirements, you'll get a $authcode on the loginCallback URL (redirect url added as in google console) & you might have specified in .env file.
• Use this authcode to generate auth token as follows:

<?php
namespace Your\App\NameSpace;

use  SahusoftCom\YoutubeApi\AuthService;	// Add Code to call the api class

$authServiceObject = new AuthService();
$authToken = $authServiceObject->getToken($authcode);

Creating a Youtube Event:

<?php
namespace Your\App\NameSpace;

use  SahusoftCom\YoutubeApi\YoutubeLiveEventService;	// Add Code to call the api class

$data = array(
	"title" => "",
	"description" => "",
	"thumbnail_path" => "",				// Optional
	"event_start_date_time" => "",
	"event_end_date_time" => "",			// Optional
	"time_zone" => "",
	'privacy_status' => "",				// default: "public" OR "private"
	"language_name" => "",				// default: "English"
	"tag_array" => ""				// Optional and should not be more than 500 characters
);

$ytEventObj = new YoutubeLiveEventService();
/**
 * The broadcast function returns array of details from YouTube.
 * Store this information & will be required to supply to youtube
 * for live streaming using encoder of your choice.
 */
$response = $ytEventObj->broadcast($authToken, $data);
if ( !empty($response) ) {

	$youtubeEventId = $response['broadcast_response']['id'];
	$serverUrl = $response['stream_response']['cdn']->ingestionInfo->ingestionAddress;
	$serverKey = $response['stream_response']['cdn']->ingestionInfo->streamName;
}

Updating a Youtube Event:

<?php
namespace Your\App\NameSpace;

use  SahusoftCom\YoutubeApi\YoutubeLiveEventService;	// Add Code to call the api class

$ytEventObj = new YoutubeLiveEventService();
/**
* The updateBroadcast response give details of the youtube_event_id,server_url and server_key.
* The server_url & server_key gets updated in the process. (save the updated server_key and server_url).
*/
$response = $ytEventObj->updateBroadcast($authToken, $data, $youtubeEventId);

// $youtubeEventId = $response['broadcast_response']['id'];
// $serverUrl = $response['stream_response']['cdn']->ingestionInfo->ingestionAddress;
// $serverKey = $response['stream_response']['cdn']->ingestionInfo->streamName

Deleting a Youtube Event:

<?php
namespace Your\App\NameSpace;

use  SahusoftCom\YoutubeApi\YoutubeLiveEventService;	// Add Code to call the api class

$ytEventObj = new YoutubeLiveEventService();
/**
 * Deleting the event requires authentication token for the channel in which the event is created and the youtube_event_id
 */
$ytEventObj->deleteEvent($authToken, $youtubeEventId);

Starting a Youtube Event Stream:

<?php
namespace Your\App\NameSpace;

use  SahusoftCom\YoutubeApi\YoutubeLiveEventService;	// Add Code to call the api class

$ytEventObj = new YoutubeLiveEventService();
/**
 * $broadcastStatus - ["testing", "live"]
 * Starting the event takes place in 3 steps
 * 1. Start sending the stream to the server_url via server_key recieved as a response in creating the event via the encoder of your choice.
 * 2. Once stream sending has started, stream test should be done by passing $broadcastStatus="testing" & it will return response for stream status.
 * 3. If transitioEvent() returns successfull for testing broadcast status, then start live streaming your video by passing $broadcastStatus="live"
 * & in response it will return us the stream status.
 */
$streamStatus = $ytEventObj->transitionEvent($authToken, $youtube_event_id,$broadcastStatus);

Stopping a Youtube Event Stream:

<?php
namespace Your\App\NameSpace;

use  SahusoftCom\YoutubeApi\YoutubeLiveEventService;	// Add Code to call the api class

$ytEventObj = new YoutubeLiveEventService();
/**
 * $broadcastStatus - ["complete"]
 * Once live streaming gets started succesfully. We can stop the streaming the video by passing broadcastStatus="complete" and in response it will give us the stream status.
 */
$ytEventObj->transitionEvent($authToken,$youtube_event_id, $broadcastStatus);	// $broadcastStatus = ["complete"]
