my $title     = $client->get_title($video_id);     # maybe encoded utf8 string.

DESCRIPTION

WWW::YouTube::Download is a library to download videos from YouTube. It relies entirely on scraping a video's webpage and does not use YT's /get_video_info URL space.

METHODS

• new()

  $client = WWW::YouTube::Download->new;
  

  Creates a WWW::YouTube::Download instance.

• download($video_id [, \%args])

  $client->download($video_id);
  $client->download($video_id, {
      fmt      => 37,
      filename => 'sample.mp4', # save file name
  });
  $client->download($video_id, {
      filename => '{title}.{suffix}', # maybe `video_title.mp4`
  });
  $client->download($video_id, {
      cb => \&callback,
  });
  

  Download the video file. The first parameter is passed to YouTube video url.

  Allowed arguments:

  • cb

    Set a callback subroutine, SEE LWP::UserAgent ':content_cb' for details.

  • filename

    Set the filename, possibly using placeholders to be filled with information gathered about the video.

    filename supported format placeholders:

    {video_id}
    {title}
    {user}
    {fmt}
    {suffix}
    {resolution}
    

    Output filename is set to {video_id}.{suffix} by default.

  • file_name

    DEPRECATED alternative for filename.

  • fmt

    set the format to download. Defaults to the best video quality (inferred by the available resolutions).

• playback_url($video_id, [, \%args])

  $client->playback_url($video_id);
  $client->playback_url($video_id, { fmt => 37 });
  

  Return playback URL of the video. This is direct link to the movie file. Function supports only "fmt" option.

• prepare_download($video_id)

  Gather data about the video. A hash reference is returned, with the following keys:

  • fmt

    the default, suggested format. It is inferred by selecting the alternative with the highest resolution.

  • fmt_list

    the list of available formats, as an array reference.

  • suffix

    the filename extension associated to the default format (see fmt above).

  • title

    the title of the video

    the video identifier

  • video_url

  • video_url_map

    an hash reference containing details about all available formats.

  The video_url_map has one key/value pair for each available format, where the key is the format identifier (can be used as fmt parameter for "download", for example) and the value is a hash reference with the following data:

  • fmt

    the format specifier, that can be passed to "download"

  • resolution

    the resolution as widthx_height_

  • suffix

    the suffix, providing a hint about the video format (e.g. webm, flv, ...)

  • url

    the URL where the video can be found

• ua([$ua])

  $self->ua->agent();
  $self->ua($LWP_LIKE_OBJECT);
  

  Sets and gets LWP::UserAgent object.
