wp_extract_url not returning query

hey Guyts

I’ve been using wp_extract_urls for a while and it suddenly seems like it not returning the full URL from the post.

$mediaurl = wp_extract_urls( get_the_content() );

the url in the post is : http://www.youtube.com/watch?v=Se1y2R5QRKU

but wp_extract_urls only returns : http://www.youtube.com/watch
