My goal: I am trying to allow users to embed a link to a Youtube video in my site, while giving me control over the player\'s settings.

I would like to do this by only a

I had to incorporate this functionality in one of my recent projects. I had to support linking both YouTube and Vimeo videos. I am using the 'uri' module of Ruby and the HTTParty. Basically I came with the following:

class LinkVideo < ActiveRecord::Base
  require 'uri'
  include HTTParty

  cattr_reader :per_page
  @@per_page = 12

  belongs_to :user

  validates :weblink, :presence => true, :domain => true


  def embed(width = "640", height = "390")
    embed_code = nil

    case base_uri
      when "www.youtube.com"
        embed_code = ""
        when "www.vimeo.com"
          embed_code = ""
      end

      embed_code
  end

  def url
    url = nil
    case base_uri
      when "www.youtube.com"
        url = "http://www.youtube.com/v/" + video_id + "&hl=en_US&fs=1"
      when "www.vimeo.com"
        url = "http://player.vimeo.com/video/" + video_id
    end

    url
  end

  def thumbnail
    url = nil
    case base_uri
      when "www.youtube.com"  
        url = "http://img.youtube.com/vi/" + video_id + "/2.jpg"
      when "www.vimeo.com"
        url = thumbnail_path( image_base_uri, video_id )
    end

    url  
  end

  # Video Paths:
  #   http://www.youtube.com/watch?v=Gqraan6sBjk
  #   http://www.vimeo.com/21618919
  # Thumbnail Paths:
  #   http://img.youtube.com/vi/Gqraan6sBjk/2.jpg
  private
    def image_base_uri
      image_base_uri = nil
      case base_uri
        when "www.youtube.com"
          image_base_uri = "http://img.youtube.com/vi/"
        when "www.vimeo.com"
          image_base_uri = "http://vimeo.com/api/v2/video/"
      end

      image_base_uri
    end

    def thumbnail_path(base_uri, videoid = nil, format = 'xml')
      path = nil

      return path if base_uri.nil?

      xml     = HTTParty.get( base_uri + ( videoid.nil? ? video_id : videoid ) + format.insert(0, '.') )
      values  = xml.parsed_response.values_at("videos").first.fetch('video')
      if values["user_portrait_medium"].include?('100')
        path  = values["user_portrait_medium"]
      else values["user_portrait_large"].include?('100')
        path = values["user_portrait_large"]
      end

      path
    end

    def base_uri
      @uri ||= parse_it

      @uri.host
    end

    def video_id
      video_id = nil
      case base_uri
        when "www.youtube.com"
          video_id = @uri.query.split('=')[1].slice(0, 11)
        when "www.vimeo.com"
          video_id = @uri.path.delete('/')
      end

      video_id
    end

    def parse_it
      @uri = URI.parse( weblink )
    end
