URL Format 1 (Traditional http://www.youtube.com/watch?v=zWw-823VTY0)
preg_match_all('#(http://www.youtube.com)?/(v/([-|~_0-9A-Za-z]+)|watch\?v\=([-|~_0-9A-Za-z]+)&?.*?)#i',$string,$output);
$output[4][0] will contain the Video ID.
URL Format 2 (New http://youtu.be/asdasdasd)
preg_match_all('#(http://youtu.be/)([-|~_0-9A-Za-z]+)#i',$string,$output);
$output[2][0] will contain the Video ID.
Vimeo (http://player.vimeo.com/video/1234567)
preg_match_all('#(http://vimeo.com)/([0-9]+)#i',$string,$output);
