I can confirm that this is broken for links like:
https://www.youtube.com/user/anjunadeep/videos
and "regular" playlists like this ID: PLOftnzGIKwJAfH33eTU2wDsBqwxOMRedV
Full link: https://www.youtube.com/watch?v=mhpfOQ6sf3s&list=PLOftnzGIKwJAfH33eTU2wDsBqwxOMRedV
or this:

Mix, search and user created playlists seem to be working just fine:
mix id to test: RDKR9wGi7gVLQ
search playlist to test: https://www.youtube.com/results?search_query=linkin+park+numb

seems widely confirmed: https://www.reddit.com/r/youtubedl/comments/jr56fs/yourubedl_sees_all_channel_links_as_empty/

I too am seeing this issue, looks to be a global thing, same problem wherever I initiate the download from

It would appear that youtube has disabled the "disable_polymer" feature that the YT extractor requires,

When visiting a playlist with the flag set, I now get unknown param

I can see the extractor is doing `

        query['disable_polymer'] = 'true'

so that is my hunch

@ainsey11 I can second what you've found there. Seems you're on the right track.

Sorry if its a dumb question: Why does the extractor need the "old theme / non-polymer"?
Is it not currently able to pull the video IDs from the new theme?

The extractor currently looks for HTML markup for each entry in a playlist. When the polymer frontend was introduced, YouTube changed from server-side rendering of HTML templates to client-side rendering. As a result, the HTML source received from the server no longer contains the markup the extractor looks for, and the only place that playlist items appear is in a JSON structure (and a fairly dense one at that). Now that the extractor can no longer opt out of polymer, it will need to be updated to pull data out of that structure.

It seems to be failing at youtube_dlc/extractor/youtube.py:_extract_playlist

Every match after these lines isn't working.

Individual video downloads still work, for example this works perfectly

how to use playlist track number from Individual video downloads? &index=2

@candrapersada That's fine as a hack, but for all of us who do archival, it's a really bad hack to put in place. Using that method, there is no way to scan the archive for all of the playlist items and avoid downloading the page for every single one of those items. I archive over 150 channels regularly and dropping down to this method would be a little bit of a disaster.

If no one has taken up the task of getting this fixed yet, I might give it a try tomorrow.

Check network tab in browser. They likely completely changed over to api usage returning json instead of html events

what I mean is how to want youtube-dlc to name the files like 1-{name}, 2-{name}, ... n-{name} in order to be able to watch them in the same sequence as original Youtube playlist. In other words I need my downloaded videos to be prefixed with numbers. How can I do that?

@candrapersada, check out the readme section called output template
if playlist downloading isn't broken, you can do
youtube-dlc -o "%(playlist_index)03d - %(title)s.%(ext)s" "https://www.youtube.com/playlist?list=..."

Hm, the playlist's title is still missing from these fixes @ZenulAbidin @insaneracist

Similar to #109.

python3.9 ./__main__.py --flat-playlist --add-metadata --all-subs -J -F 'https://youtube.com/playlist?list=PLq-W-cmkohAPAcxZWxh_ysJWPhqDxkETs'

Doesn't return a valid title key.

@arter97 fixed

Expect a release with a patch for this coming today (anything between 1-10 hrs depending on when I got time). Python version will be fixed then as well as win xp support is back then.

I was booked today, now that I have some free time I’ll see where in the JSON our variables have moved to and hopefully find a regex to match them.

That's unfortunate

Release is delayed till this issue is fixed.

@blackjack4494 Seems that the linked issue is fixed, according to comments. Would you have a potential ETA on release? Thank you 🙏

why name folder broken %(playlist)s/ and %(playlist_title)s/?

Hi everyone. I am trying to use this command to download playlist but not able to do so since past 2-3 days. Till now I can't see any fix for this. If anyone can tell me how to go past this issue it would be great help.

@harrypotter0 Which system are you using? For Manjaro Linux, a package update was available when I checked 9 hours ago, since then it works again. Some other distributions might take longer. Debian for example sometimes takes months, so you might want to download it from Github and install it that way instead.

This particular playlist is working on the latest release.
try also using --rm-cache-dir --no-cache-dir params in your command.

When I download my Youtube watch later playlist, it only downloads the first page. Any videos beyond the first 100 don't get downloaded. This happens using both youtube-dlc --cookies cookies.txt :ytwatchlater and youtube-dlc --cookies cookies.txt https://www.youtube.com/playlist?list=WL. I am using version 2020.11.11-3, and I've cleared my cache directory. I've tried messing with the --playlist-start and --playlist-end flags, but those don't seem to help either. Could this be because the watch later playlist has some unique polymer structure that got missed in the patch?

I updated to today's youtube-dl version through pip. Still, none of the auxiliary options like --rm-cache-dir --no-cache-dir seem to work. Tried to download several completely different channels' videos and yet, it always tells me, that there are only 0 videos to download, which is absolutely false.

What am I missing here? Is this truly fixed?

Try updating to master with git. Search for git in readme :)
