Isn't the playlist's title "Binomische Formeln"?

Question

however when you try

--output "./%(uploader)s/%(playlist_title)s/%(playlist_index)s_%(title)s_%(id)s.%(ext)s"

with

https://www.youtube.com/playlist?list=PLyRHCLiLznwT3gSGryiQrZtuDUnivhAAT

or any other playlist from those "mathehilfe24" people:

https://www.youtube.com/user/mathehilfe24/playlists

and many other ones I have noticed, you get as playlist title: "NA" and the .info.json files of the videos show as attribute "null" for playlist and playlist_index

...
"playlist": null,
"title": "1. binomische Formel - \u00dcbung Anwendung - als Potenz schreiben",
"creator": null,
"is_live": null,
"playlist_index": null
...

I need to have all videos belonging to a certain playlist in a separate directory and I want them prefixed with their running index. How do you do that using youtube-dl?

youtube-dl --get-filename -o '%(uploader)s/%(playlist_title)s/%(playlist_index)s_%(title)s_%(id)s.%(ext)s' https://www.youtube.com/playlist?list=PLyRHCLiLznwT3gSGryiQrZtuDUnivhAAT

OK, I was able to reproduce the error.

When you use as input parameter the playlist's id youtube-dl works as expected, but not when you go: --batch-file "<file with exactly the same yt ids/uris>"

When you use as input parameter the playlist's id youtube-dl works as expected, but not when you go: --batch-file "<file with exactly the same yt ids/uris>"

because batch files are not treated as playlists, playlist_index and playlist_title will be present only when a playlist is being downloaded.
if you want something similar to playlist_index for batch files you can use autonumber,

Not even when every line of the batch file obviously is a playlist based on the encoding that youtube itself uses? (playlists are prefixed as "PL.*" )

[remitamine]

it doesn't matter if you pass URLs in the command line or in a batch file, youtube-dl will process them the same way.
