  end
end

.get_urls_names(url) ⇒ Object

returns an array of hashes containing the download url(s) and filenames(s) for the specified video url. if the url does not match any plugin, return nil and if a plugin throws an error, throw PluginError. the reason for returning an array is because some urls will give multiple download urls (for example a Youtube playlist url).
