Description

I have tried with pip version as well as from source, and this error was raised in both build.

How to reproduce? youtube-dl https://pin.it/2r6NwmM

When the metadata for pin id 37717715606719562, to which the problem URL redirects, is fetched, there are these critical items that show why yt-dl can't find any media:

  u'videos': None,
  u'is_video': False,

The extractor should test that the first value is not None before trying to extract a video so that it reports like this, instead of a type error:

ERROR: No video formats found!; please report this issue on https://yt-dl.org/bug . Make sure you are using the latest version; see  https://yt-dl.org/update  on how to update. Be sure to call youtube-dl with the --verbose flag and include its complete output.
