Playlist information isn't added to filename when downloading individual videos.

[Ryonez]

I'm trying to include Playlist information into the filename if the video is part of a playlist. However, the file output options %(playlist)s and %(playlist_index)s do not work unless you use the playlist link itself, i.e.

https://www.youtube.com/watch?v=4SfjkpmE5-I OR https://www.youtube.com/watch?v=4SfjkpmE5-I&list=PL3tRBEVW0hiD2DcetgW0Nu-OMp7EEbUvq&index=7 DOES NOT WORK.

https://www.youtube.com/playlist?list=PL3tRBEVW0hiD2DcetgW0Nu-OMp7EEbUvq DOES WORK

This would cause issues for me when I want to watch a playlist, as I normally download videos as they come out, one at a time.

The cmd output from https://www.youtube.com/watch?v=4SfjkpmE5-I which I stop after I can see the filename is missing the Playlist information:

With https://www.youtube.com/watch?v=4SfjkpmE5-I it impossible to know which playlist the video belongs to.
https://www.youtube.com/watch?v=4SfjkpmE5-I&list=PL3tRBEVW0hiD2DcetgW0Nu-OMp7EEbUvq&index=7 works fine if you pass the URL correctly.

What? Should this be be in a "Cannot download a playlist" section in the fax?
I'm not getting any of those errors whatsoever. And I did paste the URL correctly, the way you said that kinda hurt a little >.>

Anyway, I wasn't expecting a reply so quickly! Go and enjoy Christmas mate.
