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

  140. cachedir: Location of the cache files in the filesystem.
  141. False to disable filesystem cache.
  142. noplaylist: Download single video instead of a playlist if in doubt.
  143. age_limit: An integer representing the user's age in years.

  186. * eta: The estimated time in seconds, None if unknown
  187. * speed: The download speed in bytes/second, None if
  188. unknown
  189. Progress hooks are guaranteed to be called at least once
  190. (with status "finished") if the download is successful.
  191. The following parameters are not used by YoutubeDL itself, they are used by
  192. the FileDownloader:
