AfterVideoPreviewFetchedEvent¶

New in version 12.2

The purpose of the PSR-14 event \TYPO3\CMS\Core\Resource\OnlineMedia\Event\AfterVideoPreviewFetchedEvent is to modify the preview file of online media previews (like YouTube and Vimeo). If, for example, a processed file is bad (blank or outdated), this event can be used to modify and/or update the preview file.

Example¶

EXT:my_extension/Classes/Resource/EventListener/MyEventListener.php

<?php

declare(strict_types=1);

namespace MyVendor\MyExtension\Resource\EventListener;

use TYPO3\CMS\Core\Attribute\AsEventListener;
use TYPO3\CMS\Core\Resource\OnlineMedia\Event\AfterVideoPreviewFetchedEvent;

#[AsEventListener(
    identifier: 'my-extension/after-video-preview-fetched',
)]
final readonly class MyEventListener
{
    public function __invoke(AfterVideoPreviewFetchedEvent $event): void
    {
        $event->setPreviewImageFilename(
            '/var/www/html/typo3temp/assets/online_media/new-preview-image.jpg',
        );
    }
}

New in version 13.0

The PHP attribute \TYPO3\CMS\Core\Attribute\AsEventListener has been introduced to tag a PHP class as an event listener. Alternatively, or if you need to be compatible with older TYPO3 versions, you can also register an event listener via the Configuration/Services.yaml file. Switch to an older version of this page for an example or have a look at the section Implementing an event listener in your extension.
