Detecting embedded youtube videos on WorldStar HipHop

[JMSwag]

Hey, wshh often times embeds youtube urls like this video

http://www.worldstarhiphop.com/videos/video.php?v=wshh9i6f61393imvzOo9
so.addVariable("file","http://www.youtube.com/v/z3r27ukMoMg")

the wshh ie can grab the embedded youtube url already. Since the FileDownloader sets the wshhIE as the one to use for extractions, how would one go by using the YoutubeIE after a youtube url has been detected in the webpage source?

Regular wshh video url for reference

so.addVariable("file","http://hw-videos.worldstarhiphop.com/u/vid/2012/06/18/sgswsffwretdfgetwfxetfd3tedfrdf35edf43f3f6htrg5gtrf45t43drdedew.mp4 ")

Inside the WorldStar IE in _real_extract you can return (intead of the standard dict) a info_dict with the format:

{"_type":"url",
 "url":"{the_youtube_url}"
}

You can use the helper method url_result, see https://github.com/rg3/youtube-dl/blob/master/youtube_dl/extractor/mtv.py for an example.

Once you return the url, the YoutubeDL class (the old FileDownloader) will take care of extracting the new url.
