Yes, welcome to player c5a4daa1 where the descrambling function is applied like this: ...
$o=function(a){ ...
...
... b=dx[0](b),a.set("n",b) ...
/* 5000 lines later */
var dx=[$o]; ...Patch to catch this: --- old/youtube-dl/youtube_dl/extractor/youtube.py

fix working. great job |

@dirkf + entire ytdl past/present... Prior to ytdl, procuring content was absurd - even with paid apps. This CLI-driven application is EXACTLY what is needed for archivists such as myself in this time of spiritual, culture & information wars. In no small part, I'm confident this project ( and others like it - if they exist ) have made a HUGE impact on the destiny of humanity. The [VHS Generations] are dropping dead left & right ( even before biohazard was administered under cover of healthcare )... and the bulk of this heritage was pushed to YT. YT has taken upon themselves to fail miserably as a custodian of this heritage - unceremoniously destroying untold volumes of content under direction of mentally unfit review panels with questionable motives. Without [batchable] tools to archive this content, it would be lost to future generations ( excepting those with access to the Akashic Records I suppose ). Just wanted to take a moment to recognize the team here - as the only time I (and probably everyone else) pop up is when I'm all pissed off & annoyed ( at the situation, not the tool - though its likely impossible to tell the difference). THANKS!!!!!!!!!!!! & God Bless you Catz! |

With Windows exe 2021.12.17, I'm getting throttled. Based on the patch test posted above, I think this is the patched version, right? I am not prompted for a captcha when I visit the YT page. I apologize if I have missed any other steps to un-throttling, I didn't see anything in the documentation for this situation. Edit to add: After waiting out the download, the "merging formats" step failed with "no such file or directory." |

@dirkf I'm also get throttled.. If this is a duplicate issue, where is an issue where this problem can be tracked? |

I expect you mean https://github.com/ytdl-patched/youtube-dl. See new issue #31164. |
Oups!! Yeap..
I'll monitor this, thank you. 👍 |

I wonder if #31504 is related. An exception is being raised in a Apparently we managed to overlook the JS |
|
@dirkf could you please post here when the fix is merged to the main brunch, so we can update youtube-dl (since no new releases are happening)? 🙏 |

Continued in #31509. |
