Same error with version 2016.12.22. Might be a result of some YouTube update.

[jorgicio]

The same error. Tried with 2016.12.22, 2016.12.31 and 2017.01.05.
Yes, It may be some YouTube update.

[apollo11w]

Yeah I pretty much got the same error, but I yaourt -Syu'd to version 2017-01-10 and now it's working.

[sleibrock]

Yep, that'll do it. I just ran pip install --upgrade youtube-dl and it's fine on 2017.01.10
