Class Method Details

.fetch_playlist(url, css_path) ⇒ Object

Given an URL to a HTML document and a CSS search path find the ‘data-json-href’ attribute that will give the URL for a videos playlist. This playlist will then be used to fetch all parts/chunks of a video.

Args:

url      :: Any valid URL
css_path :: A CSS expression to search, ex. Play have used '#player'

Yields:

url :: The URL from data-json-href, Play have to add modify the URL
       to make it absolute. So the caller makes any modifications
       before the JSON-file gets fetched.
       Not required to work.

Returns:

A hash with these keys:
  :title :: The title of the video
  :url   :: The URL to the playlist

def self.fetch_playlist(url, css_path)
  doc = Nokogiri::HTML(open(url).read)
  player = doc.at_css(css_path)
  stream = CGI.unescape(player['data-json-href'])
  stream = yield stream if block_given?

  js = JSON.parse(open(stream).read)
  if not js['video']['availableOnMobile']
    raise ArgumentError, "The passed in URL is not available for mobile"
  end

  title = js['context']['title']
  v = js['video']['videoReferences'].find({}) {|v| v['playerType'] == 'ios' }

  return({:title => title, :url => CGI.unescape(v['url'])}) if not v.empty?
end
