Feature Request - Add playlist number to metadata

[TwisX]

I've been using youtube-dl to download audio playlists. Instead of having to go through and manually add all the track numbers, it would be nice if youtube-dl could automatically add them to the file metadata.

(Not sure if this is the correct place to make a feature request, I'm not sure where else to put it.)

[gaming-hacker]

make a bash script, grep/find the data you want from the manifest, pipe it to key "--add-metadata"

Post an example url and explain what command you are using and what do you want it to do.

Here's a URL of a YouTube playlist: https://www.youtube.com/watch?v=cgNXw8Qh67k&list=PLYwGqFKNm0YOgUAf9D-XpRAyDPripaXiB

What I would like is for the first track to have the number 1 set as it's track number with the --add-metadata option, 2 for the second track, 3 for the third, you get the idea.
So when I import them into iTunes or some other media player I won't have to manually add the track number to each one.

I came here for a similar feature request. I'm downloading entire video playlists and I would like to have the option to have the number of the video appended to the beginning of the file name. So I can have them sorted by the sequence in the playlist.
For example:
youtube-dl https://www.youtube.com/playlist?list=PL8dPuuaLjXtMczXZUmjb3mZSU1Roxnrey
Gets files like this:
The Big Bang - Crash Course Big History #1-tq6be-CZJ3w.mp4

What I have in mind:
youtube-dl --append-playlist-number https://www.youtube.com/playlist?list=PL8dPuuaLjXtMczXZUmjb3mZSU1Roxnrey
To save files like this:
001 - The Big Bang - Crash Course Big History #1-tq6be-CZJ3w.mp4

@mohsend your request is unrelated and already implemented: output template, playlist_index.

[TRox1972]

As @dsftw says, you can use playlist_index. Should this be closed?

[yan12125]

@mohsend's question is different from @M-W99's.

[TRox1972]

Sorry, didn't notice that. But what @M-W99 is asking for is still possible, if a extractor return a value for track_number it will be added as metadata to the file if using --add-metadata. But I guess that isn't possible with YouTube, even with the -x option.

[yan12125]

Whaat @M-W99 is not talking about is not track_number but the index of individual videos/audios in a playlist.

[mohsend]

My question is answered and the feature I wanted is already present. So closing would depend on @M-W99 's opinion.

[playlistindex]

As far as I can determine, the original issue remains unresolved and mohsend's question was a bit of a highjack: he wanted to add numbers to the filename, M-W99 and I wanted to add track numbers to the metadata for each file.

Opened pull request #14991 which I believe may support the OP request
