yt-dlp needs yt-dlp-ejs to work properly on YouTube.

The latest yt-dlp needs yt-dlp-ejs to work properly, otherwise it can't read all the format on YouTube.

Re: yt-dlp needs yt-dlp-ejs to work properly on YouTube.

https://archlinux.org/packages/extra/any/yt-dlp/ has deno as hard dependency (sigh) so this should™ absolutely not be required also please don't paraphrase, https://bbs.archlinux.org/viewtopic.php?id=57855
What formats do and don't you get for what specific yt-dlp invocation of what exact yt-dlp version?

Re: yt-dlp needs yt-dlp-ejs to work properly on YouTube.

It still needs to download yt-dlp-ejs using:

--remote-components COMPONENT   Remote components to allow yt-dlp to fetch
                                when required. This option is currently not
                                needed if you are using an official
                                executable or have the requisite version of
                                the yt-dlp-ejs package installed. You can
                                use this option multiple times to allow
                                multiple components. Supported values:
                                ejs:npm (external JavaScript components from
                                npm), ejs:github (external JavaScript
                                components from yt-dlp-ejs GitHub). By
                                default, no remote components are allowed

yt-dlp-ejs is also in the AUR. Isn't this a conflict? The same package in Extra and the AUR?

Yes, but this conflict was introduced by the addition to the repo.
AUR package still needs to go, did you file a request?

Re: yt-dlp needs yt-dlp-ejs to work properly on YouTube.

Yup, that works just fine. I don't update as often as some do.
yt-dlp-2025.11.12-2-any.pkg.tar.zst

agent="Mozilla/5.0 (iPhone; CPU iPhone OS 17_5_2 like Mac OS X) \
AppleWebKit/605.1.15 (KHTML, like Gecko) CriOS/131.0.6778.154 Mobile/15E148 Safari/604.1"

yt-dlp --user-agent "$agent" -F https://m.youtube.com/watch?v=saVjKQLXXQo
...
[youtube] saVjKQLXXQo: Downloading android sdkless player API JSON

I like it. That should make yt-dlp work. Until google changes something again.

Re: yt-dlp needs yt-dlp-ejs to work properly on YouTube.

Hi, I'm having issues finding the package yt-dlp-ejs-0.3.1-1, both on the extra repo and the AUR.
As an example, this mirror returns 404 Not Found, even though the package is listed if I search through the directory.

You don't have to have that installed for youtube though. For youtube deno will download
~/.cache/yt-dlp/challenge-solver/lib.json

And, that works.

Re: yt-dlp needs yt-dlp-ejs to work properly on YouTube.

I'm not up to date. I last updated Oct 12 2025.

I then installed deno with pacman -S on oct 23 to play with it.

Later, I got yt-dlp-2025.11.12-2-any.pkg.tar.zst package and installed it manually with pacman -U on Nov 13. Yes I know, that's a partial update.

And yt-dlp works fine with deno. I don't even have yt-dlp-ejs in my pacman database yet.

So, yt-dlp is not too picky about deno version it looks like.

I built yt-dlp-ejs from source to look at it and play with it.

It will fetch during the build, 198 json files to use.

If this info is of value to anyone.
