Description

I am unable to get the filename or download this video. I am using it in python code, but even from the command line the error above occurs.

[eric-gilbertson]

I too have just started getting this error. It occurs on all my attempted downloads both on Mac and Linux.

[MCStreetguy]

Just now started getting the same error under Ubuntu 22.04 on every download i try. Cannot validate on other systems currently. Seems like something suddenly changed on YouTubes side, everything still worked perfectly fine about an hour ago. Tried downloading, dumping information only, with and without authentication, used several URLs from single videos and whole playlists, but it's always the same error for everything i tried. I was using the latest version already but also went and built a fresh version of youtube-dl myself just now from the master branch, but that also changed nothing.

My traceback looks mostly the same, except for the paths up until youtube-dl as i installed it to /usr/local/bin, but find it here anyway if required: https://pastebin.com/UBmBfZPU

[gilson-emanuel]

This error is happening to me too. Does anyone have a solution?

[daniel-gonzalez-cedre]

I just started getting this error a few hours ago as well

[raulrozza]

Just got this error as well, here on Windows

[OatsCG]

Here too on MacOS.

[Mochuleo]

Same here on Linux

[Dmi3Dev]

Confirmed on two different linux machines, both up to date. Worked fine two days ago.

[jcoy0907]

Same error on Ubuntu Server 20.04 LTS, newest commit.

[NidaCode]

I got the same Error on Windows 10. The traceback was a lot shorter. Then I tried with yt_dlp (youtube_dlp) and it worked fine with me.

[OatsCG]

It appears for me at least on MacOS that it's suddenly working fine now.

[davidecavaliere]

Another youtube downloader is suddenly failing too. From its error message seems dues to the new consent page you'd get redirected too when trying to reach a playlist without being logged in.

this :point_down: is the other downloader's error message I mentioned

[dirkf]

This is a new JS issue introduced with player 6ed0d907.

See also https://github.com/yt-dlp/yt-dlp/issues/7327.

[Sergio00166]

I have the same issue

[dirkf]

The signature JS is like this (player line 2632):

Lsa = {
  a = a.split('');
  AH.QV(a, 46);
  AH.pO(a, 1);
  AH.QV(a, 26);
  AH.LR(a, 56);
  AH.pO(a, 3);
  AH.QV(a, 24);
  AH.pO(a, 2);
  return a.join('')
};

var Lsa is declared at the start of the player. var AH is defined much later, on lines 8734-6:

var AH = {
  LR: function (a, b) {
    var c = a[0];
    a[0] = a[b % a.length];
    a[b % a.length] = c
  },
  QV: function (a) {
    a.reverse()
  },
  pO: function (a, b) {
    a.splice(0, b)
  }
};

Because of var hoisting (thanks Brendan), AH is in scope when the assignment to Lsa is executed. However, we are not constructing or passing the gigantic local context, including AH, to the signature function.

[Sergio00166]

the library yt_dlp worked fine for me

[stillearnin]

This is also happening to me.. ive tried many times. Has anyone found a solution?

[dirkf]

This is also happening to me.. ive tried many times. Has anyone found a solution?

No, have you?

[stillearnin]

I've been looking but have not found anything yet..

[dirkf]

@davidecavaliere, please open a new issue (subject to #30839) for the consent issue, if it affects yt-dl.

[dirkf]

Per https://github.com/yt-dlp/yt-dlp/issues/7327#issuecomment-1595764214, there is a short-term fix that needs to be verified before pushing to master.

[thedtvn]

same err

[dirkf]

The issue is fixed (until some new player breaks the hack) in the master code. Follow updating instructions in #31530 until a new release is made.

[dirkf]

I'll leave this open for now as a honeypot for affected users ...

I'm having the exact same error. I have the latest version installed. No matter what I've tried it still has the same error. Tried it on replit(python), window 10, linux and all have the same error.

[Arkansis2901]

Hi, i also have a problem, that my youtube-dl doesn't work for my bot. Every time when i typ in the code, it pops up an Error.... Idk why either the AI can help me or my friends, know i am asking y'all for help....
