Description

Related to #33(fixed in #57), when providing a playlist(which won't download without #57) to yt-dlc, title is NOT extracted correctly.

Reproducing step:

1. Apply [youtube] fix: extract mix playlist ids from ytInitialData (#33) #57

python3.8 ./__main__.py --flat-playlist --add-metadata --all-subs -J -F 'https://www.youtube.com/playlist?list=RDMBStYsiE618&feature=share&playnext=1' > tmp.json

python3.8 -m json.tool tmp.json > pretty.json

4. Open pretty.json

Expected result:

{
    "_type": "playlist",
    "entries": [
        # Skipped
    ],
    "id": "RDMBStYsiE618",
    "title": "Mix - BLACKPINK - ‘Lovesick Girls’ 1025 SBS Inkigayo : NO.1 OF THE WEEK",
    "extractor": "youtube:playlist",
    "webpage_url": "https://www.youtube.com/playlist?list=RDMBStYsiE618&feature=share&playnext=1",
    "webpage_url_basename": "playlist",
    "extractor_key": "YoutubePlaylist"
}

Actual result:

{
    "_type": "playlist",
    "entries": [
        # Skipped
    ],
    "id": "RDMBStYsiE618",
    "extractor": "youtube:playlist",
    "webpage_url": "https://www.youtube.com/playlist?list=RDMBStYsiE618&feature=share&playnext=1",
    "webpage_url_basename": "playlist",
    "extractor_key": "YoutubePlaylist"
}

Notice that the title is entirely missing.

As #57 fixes the download itself, I believe this should be on a separate commit/issue to fix.

Thanks!

It's the playlist title that is missing? Then I believe the regex isn't updated anymore. There are multiple ways to get playlist title. But it seems they changed the position slightly again.

Or maybe the title wasn't even returned when it was working. Haven't checked yet.

Yes, it's the playlist title.

It seems like the ones affected from #57 is returning missing title.

Not sure if this is helpful to know (or not) but both playlist and playlist_title on the latest yt-dlc are not returning title - title returns just NA or null while playlist returns playlist_id (the PLxxxxx guid). yt-dl is properly parsing both playlist and playlist_title as the actual playlist title. I know it's been months since the fork, just thought I'd point out my experience from this week.

It is fixed in #245 but since this fork has been inactive for a while, you might wanna check out my fork
