Rails helper to embed YouTube and Vimeo iframe in view

videos_helper.rb

# Helpers for better embedding and manipulation of videos
# Place this code in app/helpers/videos_helper.rb
# Then from any view you can add:
#
#    <%= get_video_iframe('http://the.video.url') %>
#
# Optionally you can add width and height.
#
#    <%= get_video_iframe('http://the.video.url', '1600px', '900px') %>

    response = Net::HTTP.get( URI.parse( uri ))

  # Main function
  # Return a video iframe
  # If the url provided is not a valid YouTube or Vimeo url it returns [nil]
  def get_video_iframe(url, width = "560px", height = "315px")
    if find_vimeo_id(url)
      get_vimeo_iframe(url, width, height) 
    elsif find_youtube_id(url)
      get_youtube_iframe(url, width, height) 
    end
  end

It'd be great to add some validation like in this piece of code
