The Vimeo API currently does not allow you to fetch the direct links for private Pro videos through their API. This `rake` task fetches the HTTP Live Streaming link so you can you `MPMoviePlayerController` in you iOS applications in stead of a webview.

vimeo.rake

namespace :vimeo do 
  
  desc "Get Vimeo HTTP Live Streaming link for private Pro videos"

  task :direct => :environment do |t,args|
    
    your_video_id = "66666666" # change this to your video id
    
		loginURL = "https://vimeo.com/log_in"
		videoFormAction = "/#{your_video_id}/settings/file"
		videoURL = "https://vimeo.com/#{videoFormAction}"

		a = Mechanize.new { |agent|
		  agent.follow_meta_refresh = true
		}

		a.get(loginURL) do |loginPage|
    
      # set xsrft token necessary to login
			token = loginPage.body.match(/xsrft: '(.*)',/)[1]
      cookie = Mechanize::Cookie.new("xsrft",token)
      cookie.domain = ".vimeo.com"
      cookie.path = "/"
      a.cookie_jar.add(a.history.last.uri,cookie)

		  # submit the login form
		  privateMemberPage = a.post('#{loginURL}',{
		  	"email" => "email@example.com",
		  	"password" => "superprivate",
		  	"action" => "login",
		  	"service" => "vimeo",
		  	"token" => token
		  	})

      vimeo_http_live_stream = "something went wrong"
		  videoFileSettingsPage = a.get(videoURL) do |videoPage|
		  	results = videoPage.body.scan(/value="(.*)" class="media_url" readonly/)
		  	vimeo_http_live_stream = results.last[0]
