  83. """YoutubeDL class.
  84. YoutubeDL objects are the ones responsible of downloading the
  85. actual video file and writing it to disk if the user has requested
  86. it, among some other tasks. In most cases there should be one per
  87. program. As, given a video URL, the downloader doesn't know how to
  88. extract all the needed information, task that InfoExtractors do, it
  89. has to pass the URL to one of them.
  90. For this, YoutubeDL objects have a method that allows
  91. InfoExtractors to be registered in a given order. When it is passed
  92. a URL, the YoutubeDL object handles it to the first InfoExtractor it
  93. finds that reports being able to handle it. The InfoExtractor extracts
  94. all the information about the video or videos the URL refers to, and
  95. YoutubeDL process the extracted information, possibly using a File
  96. Downloader to download the video.
  97. YoutubeDL objects accept a lot of parameters. In order not to saturate
  98. the object constructor with arguments, it receives a dictionary of
  99. options instead. These options are available through the params
  100. attribute for the InfoExtractors to use. The YoutubeDL also
  101. registers itself as the downloader in charge for the InfoExtractors
  102. that are added to it, so this is a "mutual registration".
  103. Available options:
  104. username: Username for authentication purposes.
  105. password: Password for authentication purposes.
  106. videopassword: Password for acces a video.
  107. usenetrc: Use netrc for authentication instead.

  109. quiet: Do not print messages to stdout.

  111. forceurl: Force printing final URL.
  112. forcetitle: Force printing title.
  113. forceid: Force printing ID.

  116. forcefilename: Force printing final filename.
  117. forceduration: Force printing duration.
  118. forcejson: Force printing info_dict as JSON.
  119. dump_single_json: Force printing the info_dict of the whole playlist
  120. (or video) as a single JSON line.
  121. simulate: Do not download the video files.
  122. format: Video format code. See options.py for more information.
