Add string for playlists with elements from multiple uploaders

[J316]

When downloading something like ".../%(uploader)s/%(playlist)s/%(title)s.%(ext)s" if the playlist contains videos from different channels a subfolder for each channel will be created. A command should be added to create a subfolder only for the creator of the playlist, for example "%(playlist_uploader)s"

Could you give some concrete examples?

@yan12125
When downloading the playlists of a channel, often those playlists contain videos from other channels talking about the same matter, so when I use a command like ".../%(uploader)s/%(playlist)s/%(title)s.%(ext)s" it downloads the videos from other authors into other folders named by the author of the video, not the author of the playlist, which is tedious. So adding a command like "%(playlist_uploader)s" would solve this issue without me entering the name of the uploader instead of the much convenient "%(uploader)s" string.

I might be unclear. Could you paste an URL of such a playlist? It would be helpful in debugging with real examples.

You could pick any, but here's an example

Thanks for the example; I see your need.

I'd like to see playlist owner/creator in --json --flat-playlist output too.

Please also add the playlist owner/creator in Python API when you come back to this issue.

Thanks!
