WWW::NicoVideo::Download is a module to login, request and download video files from Nico Nico Douga.


  $client = WWW::NicoVideo::Download->new(%options);

Creates a new WWW::NicoVideo::Download instance. %options can take the following parameters and they can also be set and get using accessor methods.

email, password
Sets and gets email and password to login Nico Nico Douga. Required if the User Agent object doesn't have the valid session or cookie to login to the site.
Sets and gets LWP::UserAgent object to use to send HTTP requests to nicovideo.jp server. If you want to reuse the browser Cookie that has the signed-in state, you can set the Cookie to the UserAgent object here.

  # use Safari sesssions
  use HTTP::Cookies::Safari;
  my $cookie_jar = HTTP::Cookies::Safari->new(
      file => "$ENV{HOME}/Library/Cookies/Cookies.plist",
  my $client = WWW::NicoVideo::Download->new;
  $client->user_agent->cookie_jar( $cookie_jar );
  $client->download($video_id, $file_path);

Prepares the download by logging in and requesting the FLV API, and then download the video file. The second parameter is passed to LWP::UserAgent's request() method, so you can pass either local file path to be saved, or a callback function.

  my $url = $client->prepare_download($video_id);

Prepares the download and returns the URL of the actual video. See eg/fetch-video.pl how to make use of this method.
