• I've verified and I assure that I'm running youtube-dl 2017.04.17

Description of your issue, suggested solution and other information

When a playlist contains a private video, --dump-single-json will fail instead of just ignoring the private video.

This is expected.

Excuse me but what's the point? What if I want to get info about all the other videos?
It's quite frustrating to have youtube-dl run for several minutes on a large playlist then fail without returning anything because there is one private video in the middle.

Bother to use search it's answered million of times.
