How does the ProductVideo module load a video preview image from YouTube or Vimeo

It uses \Magento\Framework\HTTP\Adapter\Curl:

magento/magento2/blob/c58d2d/app/code/Magento/ProductVideo/Controller/Adminhtml/Product/Gallery/RetrieveImage.php#L124-L135


protected function retrieveRemoteImage($fileUrl, $localFilePath)
{
    $this->curl->setConfig(['header' => false]);
    $this->curl->write('GET', $fileUrl);
    $image = $this->curl->read();
    if (empty($image)) {
        throw new \Magento\Framework\Exception\LocalizedException(
            __('Could not get preview image information. Please check your connection and try again.')
        );
    }
    $this->fileUtility->saveFile($localFilePath, $image);
}

public function execute()
{
    $baseTmpMediaPath = $this->mediaConfig->getBaseTmpMediaPath();
    try {
        $remoteFileUrl = $this->getRequest()->getParam('remote_image');
        $originalFileName = basename($remoteFileUrl);
        $localFileName = Uploader::getCorrectFileName($originalFileName);
        $localTmpFileName = Uploader::getDispretionPath($localFileName) . DIRECTORY_SEPARATOR . $localFileName;
        $localFileMediaPath = $baseTmpMediaPath . ($localTmpFileName);
        $localUniqueFileMediaPath = $this->appendNewFileName($localFileMediaPath);
        $this->retrieveRemoteImage($remoteFileUrl, $localUniqueFileMediaPath);
        $localFileFullPath = $this->appendAbsoluteFileSystemPath($localUniqueFileMediaPath);
        $this->imageAdapter->validateUploadFile($localFileFullPath);
        $result = $this->appendResultSaveRemoteImage($localUniqueFileMediaPath);
    } catch (\Exception $e) {
        $result = ['error' => $e->getMessage(), 'errorcode' => $e->getCode()];
    }


    /** @var \Magento\Framework\Controller\Result\Raw $response */
    $response = $this->resultRawFactory->create();
    $response->setHeader('Content-type', 'text/plain');
