How to set mpv window title to yt-dlp upload date + title

[forthrin]

$ mpv --ytdl-raw-options="output='%(upload_date)s - %(title)s'" # Doesn't work

(If possible, date formatted as YYYY-mm-dd for legibility)

--title='${metadata/by-key/date} ${media-title}'

You can format the date in a script.

That's great! Discussions and AI led nowhere. Related information:

metadata/by-key/date

$ mpv --term-status-msg='${metadata}' <file> # Show available metadata

Follow-up questions:

1. How to reformat date without going the whole route via yt-dlp -j?
2. How to add more metadata from yt-dlp? Got only these from one video at least:

ytdl_playlist_title
ytdl_playlist_id
ytdl_season
ytdl_episode
ytdl_description
title
date
series

mp.observe_property('metadata/by-key/date', 'native', function (_, date)
    if date then
        mp.set_property('title', date:sub(1, 4) .. '-' .. date:sub(5, 6) .. '-' .. date:sub(7, 8) .. ' ${media-title}')
    else
        mp.set_property('title', '${?media-title:${media-title}}${!media-title:No file} - mpv')
    end
end)
