google drive "No video thumbnail for this post."

Can you provide an example of a video it didn’t work for?

I can see what the problem is, and will have a fix in the next update. If you’d like to go ahead and fix it yourself, you can edit the file in wp-content/plugins/video-thumbnails/php/providers/class-googledrive-thumbnails.php by replacing the section that starts with

// Regex strings

with this

// Regex strings
	public $regexes = array(
		'#(?:https?:)?//docs\.google\.com/(?:a/[^/]+/)?file/d/([A-Za-z0-9\-_]+)/preview#', // iFrame URL
		'#(?:https?:)?//video\.google\.com/get_player\?docid=([A-Za-z0-9\-_]+)#', // Flash URL
		'#<param value="(?:[^"]+)?docid=([A-Za-z0-9\-_]+)(?:[^"]+)?" name="flashvars">#', // Flash (YouTube player)
	);
