Description of your issue, suggested solution and other information

Hey Guys. I wrote a script last year that downloads trailers from Fandango's trailer list and adds them to Plex before they're in theaters and removes them when they hit. So that way when you sit down to watch a movie on plex, there will be a configurable amount of trailers before the movie starts of all new movies that are coming out. The link can be found here.

Anyway I ran into an issue on my installation that youtube-dl throws ERROR: Unable to extract title;. I am able to use the command line version to download but when I try to embed it in python code and download info from playlists, it gives me this error. I did install from pypi. On my host when I use the command line version, it shows 2017.09.2, however in the process of filling out a bug report, I noticed in the verbose output, its using 2016.08.19. I've looked through the issues and generally when this happens the answer seems to be "You'll need to update to the latest version" so I'm sure that it is it. I used pip list to show that its running the 2017.09.2 version as well as youtube-dl --version.

Playlist I was trying to download from: https://www.youtube.com/playlist?list=PLScC8g4bqD47c-qHlsfhGH3j6Bg7jzFy-

Any ideas?

Other Info

• python: 2.7.12
• os: Ubuntu 16.04.3 LTS
• kernel: 4.4.0-92-generic
• I do not have youtube-dl installed through apt (I thought maybe it got installed twice thus the version mismatch)
• I did try uninstalling and reinstalling ¯\_(ツ)_/¯

In case anyone else comes across this, apparently pip in my specific case, was only installing and updating the python 3.5 version, so I needed to specify pip2. Closing issue
