Embedding youtube-dl
youtube-dl is callable from any programming language. In this tutorial, we'll call it from our Python code.
youtube-dl's README.md shows us a brief introduction to embedding.
Also, have a look at my previous tutorial: Downloading YouTube, Vimeo etc Videos using youtube-dl.
Our first embedded code
The following code might be the simplest. It just download a YouTube video.
# ydl1.py
from __future__ import unicode_literals
import youtube_dl
ydl_opts = {}
with youtube_dl.YoutubeDL(ydl_opts) as ydl:
ydl.download(['https://www.youtube.com/watch?v=dP15zlyra3c'])
Run it:
$ python ydl1.py [youtube] dP15zlyra3c: Downloading webpage [youtube] dP15zlyra3c: Downloading video info webpage [youtube] dP15zlyra3c: Extracting video information [youtube] dP15zlyra3c: Downloading DASH manifest [youtube] dP15zlyra3c: Downloading DASH manifest [download] Destination: Fox Snow Dive - Yellowstone - BBC Two-dP15zlyra3c.f137.mp4 [download] 100% of 13.25MiB in 00:08 [download] Destination: Fox Snow Dive - Yellowstone - BBC Two-dP15zlyra3c.f141.m4a [download] 100% of 1.78MiB in 00:04 [ffmpeg] Merging formats into "Fox Snow Dive - Yellowstone - BBC Two-dP15zlyra3c.mp4" Deleting original file Fox Snow Dive - Yellowstone - BBC Two-dP15zlyra3c.f137.mp4 (pass -k to keep) Deleting original file Fox Snow Dive - Yellowstone - BBC Two-dP15zlyra3c.f141.m4a (pass -k to keep)
Using options
The list of options is available at youtube_dl/YoutubeDL.py.
We'll use the following list of options:
- format: format code
- outtmpl: Template for output names.
- noplaylist: Download single video instead of a playlist if in doubt.
#ydl2.py
from __future__ import unicode_literals
import youtube_dl
def my_hook(d):
if d['status'] == 'finished':
print('Done downloading, now converting ...')
ydl_opts = {
'format': 'bestaudio/best',
'outtmpl': '%(id)s',
'noplaylist' : True,
'progress_hooks': [my_hook],
}
with youtube_dl.YoutubeDL(ydl_opts) as ydl:
ydl.download(['https://www.youtube.com/watch?v=pwp1CH5R-w4'])
Run the code:
$ python ydl2.py [youtube] pwp1CH5R-w4: Downloading webpage [youtube] pwp1CH5R-w4: Downloading video info webpage [youtube] pwp1CH5R-w4: Extracting video information [youtube] pwp1CH5R-w4: Downloading DASH manifest [youtube] pwp1CH5R-w4: Downloading DASH manifest [download] Destination: pwp1CH5R-w4 [download] 100% of 10.82MiB in 00:13 Done downloading, now converting ... [ffmpeg] Correcting container in "pwp1CH5R-w4"
The file is stored with id (pwp1CH5R-w4) as its name. The format is mp4a.
Getting meta information
How about getting information about a video?
Retrieving meta info is rather simple.
The code looks like this:
#ydl3.py
from __future__ import unicode_literals
import youtube_dl
ydl_opts = {}
with youtube_dl.YoutubeDL(ydl_opts) as ydl:
meta = ydl.extract_info(
'https://www.youtube.com/watch?v=9bZkp7q19f0', download=False)
print 'upload date : %s' %(meta['upload_date'])
print 'uploader : %s' %(meta['uploader'])
print 'views : %d' %(meta['view_count'])
print 'likes : %d' %(meta['like_count'])
print 'dislikes : %d' %(meta['dislike_count'])
print 'id : %s' %(meta['id'])
print 'format : %s' %(meta['format'])
print 'duration : %s' %(meta['duration'])
print 'title : %s' %(meta['title'])
print 'description : %s' %(meta['description'])
Note that we're getting the meta info without downloading the video (download=False).
