   1 Using the ``youtube_dl`` module
   2 ===============================
   3
   4 When using the ``youtube_dl`` module, you start by creating an instance of :class:`YoutubeDL` and adding all the available extractors:
   5
   6 .. code-block:: python
   7
   8     >>> from youtube_dl import YoutubeDL
   9     >>> ydl = YoutubeDL()
  10     >>> ydl.add_default_info_extractors()
  11
  12 Extracting video information
  13 ----------------------------
  14
  15 You use the :meth:`YoutubeDL.extract_info` method for getting the video information, which returns a dictionary:
  16
  17 .. code-block:: python
  18
  19     >>> info = ydl.extract_info('http://www.youtube.com/watch?v=BaW_jenozKc', download=False)
  20     [youtube] Setting language
  21     [youtube] BaW_jenozKc: Downloading webpage
  22     [youtube] BaW_jenozKc: Downloading video info webpage
  23     [youtube] BaW_jenozKc: Extracting video information
  24     >>> info['title']
  25     'youtube-dl test video "\'/\\ä↭𝕐'
  26     >>> info['height'], info['width']
  27     (720, 1280)
  28
  29 If you want to download or play the video you can get its url:
  30
  31 .. code-block:: python
  32
  33     >>> info['url']
  34     'https://...'
  35
  36 Extracting playlist information
  37 -------------------------------
  38
  39 The playlist information is extracted in a similar way, but the dictionary is a bit different:
  40
  41 .. code-block:: python
  42
  43     >>> playlist = ydl.extract_info('http://www.ted.com/playlists/13/open_source_open_world', download=False)
  44     [TED] open_source_open_world: Downloading playlist webpage
  45     ...
  46     >>> playlist['title']
  47     'Open-source, open world'
  48
  49
  50
  51 You can access the videos in the playlist with the ``entries`` field:
  52
  53 .. code-block:: python
  54
  55     >>> for video in playlist['entries']:
  56     ...     print('Video #%d: %s' % (video['playlist_index'], video['title']))
