Wie rufe ich einzelne Video-URLs aus einer Wiedergabeliste ab und verwende YouTube-DL in einem Python-Skript? ⇐ Python

[Anonymous]

Ich versuche: < /p>


Verwenden Sie YouTube-DL innerhalb eines Python-Skripts, um Videos regelmäßig herunterzuladen. 'Mp3' < /li>
< /ul>

Ich bin ziemlich neu in Python und ich bin sicher, dass es einige unordentliche, unnötige Code -Teile gibt. Ich bin also auch offen für Aufräumberatung. (Und ich weiß nicht, wie oder ob ich im gesamten Code nur die OutMPL -Option /Variable verwenden kann) < /p>

Ich habe den Code tatsächlich in drei Teile /Module aufgeteilt.

Code: Select all

outmpl: 'F:\\Videos\\Online Videos\\Comics\\%(uploader)s\\%(playlist)s\\%(playlist_index)s_%(title)s.%(ext)s'
< /code>

, wodurch die Videos in: < /p>

speichern würden'F:\\Videos\\Online Videos\\Comics\\Comicstorian\\Annhililation\\01_Annihilation Beginnings Drax Earthfall - Complete Story.mp4' - and so on (for the rest of the videos)
< /code>

Aber ich weiß nicht, dass ich die Verzeichnisvariablen an das Modul weitergeben soll, in dem ich die Dateien verschiebe. />

Code here should get take the youtube playlist and spit out
each url to move to the next step as vLinks variable, but
I haven't figured out how to pass (title) etc. variables from
each video in a playlist.

link = individual video url from playlist

The following puts actual info into variables for Python to use. These are made global above.  I made a 'for' loop to repeat grabbing info for each video - but it doesn't work right now b/c I didn't define vLinks.
'''
for vLink in vLinks:
info_dict = ydl.extract_info(link, download=False)
video_title = info_dict.get('title', None)
playlist_index = info_dict.get('playlist_index', None)
playlist = info_dict.get('playlist', None)
uploader = info_dict.get('uploader', None)
print(video_title)

#Checks if the video is in a playlist; if it's not, 'NA' will be the string returned: http://stackoverflow.com/questions/23086383/how-to-test-nonetype-in-python

if playlist is None:
playlist = 'NA'

if playlist_index is None:
playlist_index = 'NA'
