Metadata type old-fashioned

Hi,

great job with your plugin! Thanks for adding metadata for iframes.

One thing I wanted to mention: the metadata style you’re using seems to be outdated (at least it’s not recognised by Google) So it’s pretty useless right now 🙁

I tried changing the /includes/generate-embed-code.php file to adapt schema.org metadata, but it always crashes anything when I want change sth (I’m bad at PHP…)

Here’s the code I tried:

// Add IFRAME embed code

	if ( ( $iframe ) or ( ( $embedplus ) && ( $fallback == "v" ) ) ) {
		if ( $embed_type == "p" ) { $playlist_para = "p/"; } else { $playlist_para = ''; }
		if ( $metadata != 0 ) { $result .= $tab . '<div itemprop="video" itemscope itemtype="http://schema.org/VideoObject">' . "\n"; $tab .= $tab; }
		$result .= $tab . '<iframe ' . $frameborder . 'style="border: 0;' . $style . '" class="' . $class . '" width="' . $width . '" height="' . $height . '" src="' . $embed_url . '&wmode=' . $wmode . '"';
		if ( $fullscreen == 1 ) { $result .= ' allowfullscreen="allowfullscreen"'; }
		$result .= " ></iframe>\n";
		if ( $metadata != 0 ) {
			$result .= $tab . '<meta itemprop="embedURL" content="http' . $https . '://www.youtube.com/' . $embed_type . '/' . $id . '" />' . "\n";
			$result .= $tab . '<meta itemprop="thumbnailUrl" content="http://i.ytimg.com/vi/' . $id . '/maxresdefault.jpg"/>' . "\n";
			$result .= $tab . '<meta itemprop="thumbnailUrl" content="http://i.ytimg.com/vi/' . $id . '/hqdefault.jpg"/>' . "\n";
			$result .= $tab . '<meta itemprop="thumbnailUrl" content="http://i.ytimg.com/vi/' . $id . '/default.jpg"/>' . "\n";
			$result .= $tab . '<meta itemprop="width" content="' . $width . '"/>' . "\n";
			$result .= $tab . '<meta itemprop="height" content="' . $height . '"/>' . "\n";
			$tab = "\t";
			$result .= $tab . '</div>' . "\n";
		}
	}

Could you change adapt that in a way it works? 😀
PS: Google recommends this metadata style.

Thanks a lot, Apple Werbung
