Wordpress - Generating Thumbnails for video

You can use the oEmbed functionality baked into WordPress. Typically any video host on this list will return a thumbnail to you using oembed.

Here is a list of default providers that WordPress uses for auto embedding in the content area. I've included non-video sources as well for the convenience of others.

• http://www.youtube.com/oembed
• http://blip.tv/oembed/
• http://vimeo.com/api/oembed.xml
• http://www.dailymotion.com/api/oembed/
• http://www.flickr.com/services/oembed/
• http://api.smugmug.com/services/oembed/
• http://www.hulu.com/api/oembed.xml
• http://lab.viddler.com/services/oembed/
• http://qik.com/api/oembed.xml
• http://revision3.com/api/oembed/
• http://photobucket.com/oembed
• http://photobucket.com/oembed
• http://www.scribd.com/services/oembed
• http://wordpress.tv/oembed/
• http://polldaddy.com/oembed/
• http://www.funnyordie.com/oembed

The full list of possible providers is documented at the WordPress codex under:
Embeds - Okay, So What Sites Can I Embed From?

Select your provider then use the following to get your video information.

require_once(ABSPATH.'wp-includes/class-oembed.php');
$oembed= new WP_oEmbed;
$url = 'http://www.youtube.com/watch?v=oHg5SJYRHA0';
//As noted in the comments below, you can auto-detect the video provider with the following
$provider = $oembed->discover($url);
//$provider = 'http://www.youtube.com/oembed';
$video = $oembed->fetch($provider, $url, array('width' => 300, 'height' => 175));
$title = $video->title;
$html = $video->html;
$thumb = $video->thumbnail_url;

I realize VideoBuzzy is not on the list. It appears to be a YouTube knockoff site. You should ask them if they have oembed protocols. If they don't, you can register a non oembed handler by using wp_embed_register_handler().

Hope this helps!

You can use this plugin Wordpress Video Plugin and edit the code of this plugin and add the other sites in it.
