In most cases there should be one per\n     |  program. As, given a video URL, the downloader doesn't know how to\n     |  extract all the needed information, task that InfoExtractors do, it\n     |  has to pass the URL to one of them.\n     |  \n     |  For this, YoutubeDL objects have a method that allows\n     |  InfoExtractors to be registered in a given order. When it is passed\n     |  a URL, the YoutubeDL object handles it to the first InfoExtractor it\n     |  finds that reports being able to handle it. The InfoExtractor extracts\n     |  all the information about the video or videos the URL refers to, and\n     |  YoutubeDL process the extracted information, possibly using a File\n     |  Downloader to download the video.\n     |  \n     |  YoutubeDL objects accept a lot of parameters. In order not to saturate\n     |  the object constructor with arguments, it receives a dictionary of\n     |  options instead. These options are available through the params\n     |  attribute for the InfoExtractors to use. The YoutubeDL also\n     |  registers itself as the downloader in charge for the InfoExtractors\n     |  that are added to it, so this is a \"mutual registration\".\n     |  \n     |  Available options:\n     |  \n     |  username:          Username for authentication purposes.\n     |  password:          Password for authentication purposes.\n     |  videopassword:     Password for accessing a video.\n     |  ap_mso:            Adobe Pass multiple-system operator identifier.\n     |  ap_username:       Multiple-system operator account username.\n     |  ap_password:       Multiple-system operator account password.\n     |  usenetrc:          Use netrc for authentication instead.\n     |  verbose:           Print additional info to stdout.\n     |  quiet:             Do not print messages to stdout.\n     |  no_warnings:       Do not print out anything for warnings.\n     |  forceurl:          Force printing final URL.\n     |  forcetitle:        Force printing title.\n     |  forceid:           Force printing ID.\n     |  forcethumbnail:    Force printing thumbnail URL.\n     |  forcedescription:  Force printing description.\n     |  forcefilename:     Force printing final filename.\n     |  forceduration:     Force printing duration.\n     |  forcejson:         Force printing info_dict as JSON.\n     |  dump_single_json:  Force printing the info_dict of the whole playlist\n     |                     (or video) as a single JSON line.\n     |  simulate:          Do not download the video files.\n     |  format:            Video format code.
