Using the ``yt_dlp`` module
|
||||
===============================
|
||||
|
||||
When using the ``yt_dlp`` module, you start by creating an instance of :class:`YoutubeDL` and adding all the available extractors:
|
||||
|
||||
.. code-block:: python
|
||||
|
||||
>>> from yt_dlp 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)
|
||||

|
||||
>>> 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']))
