[youtube] More than one link return for a youtube url

[ghost]

Hi,

I'm trying to extract some info from a youtube link using youtube-dl. When I run the following command,

youtube-dl -o "%(title)s.%(ext)s" --get-url --get-filename "https://www.youtube.com/watch?v=a0oQy7jgH_w"

it returns two different links and video title with a warning message,

WARNING: [youtube] a0oQy7jgH_w: Skipping DASH manifest: ExtractorError(u'Cannot decrypt signature without player_url; 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.',)

It should return only one link with a video title. I guess youtube have changed something and it breaks youtube-dl.

Here is my configuration:

youtube-dl now defaults to downloading DASH video and audio and then merges them (they give a better quality result). If you only want to get normal formats, you can use -f best.

Note that for doing anything serious with the output of youtube-dl you should use the --dump-json option.
