  87. """YoutubeDL class.
  88. YoutubeDL objects are the ones responsible of downloading the
  89. actual video file and writing it to disk if the user has requested
  90. it, among some other tasks. In most cases there should be one per
  91. program. As, given a video URL, the downloader doesn't know how to
  92. extract all the needed information, task that InfoExtractors do, it
  93. has to pass the URL to one of them.
  94. For this, YoutubeDL objects have a method that allows
  95. InfoExtractors to be registered in a given order. When it is passed
  96. a URL, the YoutubeDL object handles it to the first InfoExtractor it
  97. finds that reports being able to handle it. The InfoExtractor extracts
  98. all the information about the video or videos the URL refers to, and
  99. YoutubeDL process the extracted information, possibly using a File
  100. Downloader to download the video.
  101. YoutubeDL objects accept a lot of parameters. In order not to saturate
  102. the object constructor with arguments, it receives a dictionary of
  103. options instead. These options are available through the params
  104. attribute for the InfoExtractors to use. The YoutubeDL also
  105. registers itself as the downloader in charge for the InfoExtractors
  106. that are added to it, so this is a "mutual registration".
  107. Available options:
  108. username: Username for authentication purposes.
  109. password: Password for authentication purposes.
  110. videopassword: Password for acces a video.
  111. usenetrc: Use netrc for authentication instead.
  112. verbose: Print additional info to stdout.
  113. quiet: Do not print messages to stdout.
  114. no_warnings: Do not print out anything for warnings.
  115. forceurl: Force printing final URL.
  116. forcetitle: Force printing title.
  117. forceid: Force printing ID.
  118. forcethumbnail: Force printing thumbnail URL.
  119. forcedescription: Force printing description.
  120. forcefilename: Force printing final filename.
  121. forceduration: Force printing duration.
  122. forcejson: Force printing info_dict as JSON.
  123. dump_single_json: Force printing the info_dict of the whole playlist
  124. (or video) as a single JSON line.
  125. simulate: Do not download the video files.
  126. format: Video format code. See options.py for more information.
  127. outtmpl: Template for output names.
  128. restrictfilenames: Do not allow "&" and spaces in file names
  129. ignoreerrors: Do not stop on download errors.
  130. nooverwrites: Prevent overwriting files.
  131. playliststart: Playlist item to start at.
  132. playlistend: Playlist item to end at.
  133. playlist_items: Specific indices of playlist to download.
  134. playlistreverse: Download playlist items in reverse order.
  135. matchtitle: Download only matching titles.
  136. rejecttitle: Reject downloads for matching titles.
  137. logger: Log messages to a logging.Logger instance.
