Changing enfold with child theme

Great, this works!

By the way, the code I changed/added is this:

masonry_entries.php, from line 770:

							case 'video' :
								if(!$this->loop[$key]['thumb_ID']) 
								{
									preg_match_all('#\bhttps?://[^\s()<>]+(?:\([\w\d]+\)|([^[:punct:]\s]|/))#', $entry->post_content, $match);
									foreach($match[0] as $test_url){
										if($this->loop[$key]['video_image_url']=video_get_image_url ($test_url))
											break;
									}
									if($this->loop[$key]['video_image_url']=="")
											$this->loop[$key]['text_before'] = av_icon_display($post_format);
								}
								else
									$this->loop[$key]['text_before'] = av_icon_display($post_format, 'av-masonry-media');
								break;

…and line 863:

				//get attachment data
				$this->loop[$key]['attachment'] = !empty($this->loop[$key]['thumb_ID']) ? wp_get_attachment_image_src($this->loop[$key]['thumb_ID'], $img_size) : array($this->loop[$key]['video_image_url']);

and in functions.php this function:

// Video-URL
function video_get_image_url($url,$size="thumbnail_large"){
	$image_src = parse_url($url);
	if($image_src['host'] == 'www.vimeo.com' || $image_src['host'] == 'vimeo.com' || $image_src['host'] == 'player.vimeo.com'){
		parse_str($image_src['query'], $query);
		if(isset($query['clip_id']) && $query['clip_id'] != ""){
			$id = $query['clip_id'];
		} else {
			$path = explode("/",$image_src['path']);
			$id = $path[(count($path)-1)];
		}
		if(function_exists('curl_init')){;
			$ch = curl_init();
			curl_setopt($ch, CURLOPT_URL, "http://vimeo.com/api/v2/video/$id.php");
			curl_setopt($ch, CURLOPT_HEADER, 0);
			curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
			curl_setopt($ch, CURLOPT_TIMEOUT, 10);
			$output = unserialize(curl_exec($ch));
			$output = $output[0][$size];
			curl_close($ch);
			return $output;	
		}
	}
	else if($image_src['host'] == 'www.youtube.com' || $image_src['host'] == 'youtube.com'){
		parse_str($image_src['query'], $query);
		if(isset($query['v']) && $query['v'] != ""){
			$id = $query['v'];
		} else {
			$path = explode("/",$image_src['path']);
			$id = $path[count($path)-1];
		}
		if($size=="thumbnail_large")
			return "http://img.youtube.com/vi/".$id."/0.jpg";				
		else
			return "http://img.youtube.com/vi/".$id."/default.jpg";				
	} else{
		return false;
	}
}

Voilá – now every post content of type “video” in the masonry automagically displays the cover image of the first video of the post instead of only the video icon. Wouldn’t this feature be nice for a future enfold update? :-)
