Description

Trying to extract the list of playlists for some channels only returns about 11 entries, when they actually have more (in this case, 41.) It seems the ones extracted were the final 11 entries.

This only happens with some channels; I've been able to extract a list of 400+ playlists of another channel.

The 11 are found in a continuation; the missing items should be found in a LOCKUP_VIEW_MODEL that the extractor doesn't understand.

The tab extractor needs an overhaul which will be included in the final resolution of #32905. Meanwhile a partial update can be pushed (yt-dlp back-port) that has this result:

Do you know why disable_polymer=1 is being used and/or what its effect is?

It was an old URL; I used to put disable_polymer=1 to URLs so that youtube would serve its legacy non-polymer (i.e. not slow as hell) interface when I opened the bookmark. Now they always serve the polymer interface (started around the time when the youtube:tab rewrite was/had to be done) ...

Appears to be back; I can only get a maximum of 30 playlists from a channel.

Might this also get the missing continuation for the Shorts page?

This appears to have been completely broken, either by youtube changes or recent changes in ytdl: no playlists are listed at all today when I tested on 2025.11.21 [d0283f538].

Broken by recent changes in ytdl, it seems; I tested with a May 4 version of youtube-dl and it works, shows 25-30 playlists like it used to do.

Seems like LOCKUP_VIEW_MODEL appeared in the main playlist page, causing the 1st 30 videos to be skipped. After fixing that, it appeared in the continuation data, causing the last 11 videos to be skipped, because its name did not glob-match GRID*RENDERER.
