Magento – Display product video in product description tab

Yes, in the rwd theme there is a reviews tab on the product page by default.

The most common ways to remove them would be

• "Disable Module Output" in System > Configuration > Advanced
• Layout XML update: <remove name="product.reviews" />
• Layout XML override (review.xml in your theme) where the catalog_product_view handle is removed

If none of these is the case, search your custom code for "review", there are countless "creative" ways to accomplish anything in Magento.

You can get Media collection of particular product by loading it in custom helper as below:

<?php
namespace Your\Module\Helper;

use Magento\Catalog\Api\ProductRepositoryInterface;

class Data extends \Magento\Framework\Url\Helper\Data
{
    public function __construct(
        ...
        ProductRepositoryInterface $productRepository,
        ...
    ) {
        ...
        $this->productRepository = $productRepository;
        ...
    }

    public function getMediaGalleryImages($product)
    {
        $_product = $this->productRepository->get($product->getSku(), false, null, true);

        return $_product->getMediaGalleryImages();
    }
}

Please copy

vendor/magento/module-catalog/view/frontend/templates/product/list.phtml

to your custom theme.

app/design/frontend/package/theme/Magento_Catalog/templates/product/list.phtml

Now in list.phtml file, you can call this function to load the video url if it's available otherwise show the regular image:

<?php
$video = false;
$galleryImages = $this->helper('Your\Module\Helper\Data')->getMediaGalleryImages($_product);
if ($galleryImages) {
    foreach ($galleryImages as $primage) {
        $imageData = $primage->getData();
        // Check media type
        if (isset($imageData['media_type']) && $imageData['media_type'] == 'external-video') {
            $video = true;
            if (strpos($imageData['video_url'], 'youtube.com') !== false) {
                echo preg_replace("/\s*[a-zA-Z\/\/:\.]*youtube.com\/watch\?v=([a-zA-Z0-9\-_]+)([a-zA-Z0-9\/\*\-\_\?\&\;\%\=\.]*)/i","<iframe width=\"240\" height=\"300\" src=\"//www.youtube.com/embed/$1\" frameborder=\"0\" allowfullscreen></iframe>", $imageData['video_url']);
            }elseif(strpos($imageData['video_url'], 'vimeo.com') !== false){
                echo "<iframe width=\"240\" height=\"300\" src=".$imageData['video_url']." frameborder=\"0\" allowfullscreen></iframe>";
            }
        }
    }
}
?>

<?php if(!$video){ ?>
    <?= $productImage->toHtml() ?>
<?php } ?>

For vimeo, add embedded urls for product video to make them playable at list page. Please note that it would take some extra time to load page first time as we are loading product to get media collection.
