You can also try quvi gem which can extract most metadata from many media sites. For example you can get URLs of streams and pass them to downloader of your choice:

require 'quvi'

q = Quvi::Handle.new
media = q.parse_media("https://soundcloud.com/tasod/taso-du-val-originally-superior-ep-1")
media[:streams].map{ |m| m[:url] }
# => ["http://media.soundcloud.com/stream/U203a5DmFj9U?stream_token=1Q17x"]

you can use the standard open when including openuri like this:

require 'open-uri'
youtube_video  = open('http://www.yotube.com/whatever') {|f| f.read }
