Pytube: Pytube length sometimes missing causes crash

[chris-saunders]

On certain urls trying to get the length of a youtube video crashes the program due to a key error in the object itself.

Ex:
https://www.youtube.com/watch?v=4VR-6AS0-l4

Traceback (most recent call last):
    if end_time >= yt.length:
  File "/opt/python/run/venv/lib/python2.7/site-packages/pytube/__main__.py", line 286, in length
    return self.player_config_args['length_seconds']
KeyError: 'length_seconds'

i've got the same error with all the videos i tried :-(

[marcounetB]

hey i figured out what is happening !
Go to line 286 and change the only line with
return ( self.player_config_args .get('player_response', {}) .get('videoDetails', {}) .get('lengthSeconds') )
It works really well for me ;-)

@marcounetB nailed it!
However, if you don't want to edit the source code... considering you have your object like current_video = YouTube(video_url), you just need to use:

current_video.player_config_args.get('player_response').get('videoDetails').get('lengthSeconds')
or
current_video.player_config_args['player_response']['videoDetails']['lengthSeconds']

Happy downloading :)

I have the same problem, I'm using v9.5.2. I see there's a fix here: https://github.com/nficano/pytube/pull/443. Hopefully it'll be patched soon meanwhile I'm using @ricardodeazambuja solution
