Using the ``youtube_dl`` module
===============================
When using the ``youtube_dl`` module, you start by creating an instance of :class:`YoutubeDL` and adding all the available extractors:
.. code-block:: python
    >>> from youtube_dl import YoutubeDL
    >>> ydl = YoutubeDL()
    >>> ydl.add_default_info_extractors()
Extracting video information
----------------------------
You use the :meth:`YoutubeDL.extract_info` method for getting the video information, which returns a dictionary:
.. code-block:: python
    >>> info = ydl.extract_info('http://www.youtube.com/watch?v=BaW_jenozKc', download=False)
    [youtube] Setting language
    [youtube] BaW_jenozKc: Downloading webpage
    [youtube] BaW_jenozKc: Downloading video info webpage
    [youtube] BaW_jenozKc: Extracting video information
    >>> info['title']
    'youtube-dl test video "\'/\\ä↭𝕐'
    >>> info['height'], info['width']
    (720, 1280)
If you want to download or play the video you can get its url:
.. code-block:: python
    >>> info['url']
    'https://...'
Extracting playlist information
-------------------------------
The playlist information is extracted in a similar way, but the dictionary is a bit different:
.. code-block:: python
    >>> playlist = ydl.extract_info('http://www.ted.com/playlists/13/open_source_open_world', download=False)
    [TED] open_source_open_world: Downloading playlist webpage
    ...
    >>> playlist['title']
    'Open-source, open world'
You can access the videos in the playlist with the ``entries`` field:
.. code-block:: python
    >>> for video in playlist['entries']:
    ...     print('Video #%d: %s' % (video['playlist_index'], video['title']))
