YouTube id contents in TYPO3 Flux FAL Object - typo3

Question

I have a YouTube Video as a FAL Object and i need the YouTube id in my Fluid Template.
In a FileReference Object it is possible to get the id via {file.contents}.
But i can't find the YouTube id in the FAL Array from a flux:field.inline.fal
In my flux Content Template i get the Video FAL Array like this:
{v:content.resources.fal(field: 'settings.falimage', record:record) -> v:iterator.first() -> v:variable.set(name: 'image')}
In the recieved Array i only find the url to the YouTube Video. Is there a getter or ViewHelper for that?
My Setup:
TYPO3 9.5.9
Flux 9.2.0
VHS 5.2.0

Answer 1

After the failed attempt to use the VHS PregMatchViewHelper (https://fluidtypo3.org/viewhelpers/vhs/development/Variable/PregMatchViewHelper.html) in conjunction with the pattern https://gist.github.com/ghalusa/6c7f3a00fd2383e5ef33 i ended up creating an own ViewHelper that finds the YouTube id from an url:
<?php
use TYPO3Fluid\Fluid\Core\Rendering\RenderingContextInterface;
use TYPO3Fluid\Fluid\Core\ViewHelper\AbstractViewHelper;
use TYPO3Fluid\Fluid\Core\ViewHelper\Traits\CompileWithRenderStatic;
/**
* A view helper for rendering the YouTube Id from an url
*
* = Examples =
*
* <code>
* {nc:youTubeId(url: 'https://www.youtube.com/watch?v=zpOVYePk6mM')}
* </code>
* <output>
* zpOVYePk6mM
* </output>
*/
class YouTubeIdViewHelper extends AbstractViewHelper
{
use CompileWithRenderStatic;
/**
* Initialize arguments
*/
public function initializeArguments()
{
$this->registerArgument('url', 'string', 'YouTube url', true);
}
/**
* #param array $arguments
* #param \Closure $renderChildrenClosure
* #param RenderingContextInterface $renderingContext
* #return string youtube id
*/
public static function renderStatic(array $arguments, \Closure $renderChildrenClosure, RenderingContextInterface $renderingContext)
{
$url = $arguments['url'];
preg_match('%(?:youtube(?:-nocookie)?\.com/(?:[^/]+/.+/|(?:v|e(?:mbed)?)/|.*[?&]v=)|youtu\.be/)([^"&?/ ]{11})%i', $url, $match);
$youtube_id = $match[1];
return $youtube_id;
}
}
