  my $client = WWW::YouTube::Download->new;
  $client->download($video_id);

  my $video_url = $client->get_video_url($video_id);

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 supported format placeholders:

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

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

fmt

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

resolution

the resolution as widthxheight

suffix

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