ejs

yt-dlp was very recently broken for ~2 days for any Youtube videos that required cookies: https://github.com/yt-dlp/yt-dlp/issues/16212 Here is what actually fixed it: https://github.com/yt-dlp/ejs/pull/53/changes yt-dlp is relatively stable, but still occasionally breaks for long periods. I get the sense YouTube is becoming increasingly adversarial to yt-dlp as well. I don't know the details, but it doesn't seem like yt-dlp is running the entire YouTube JS+DOM environment. Something like a real headless browser seems like it would break less often, but be much heavier weight. And Youtube might have all sorts of other mitigations against this approach.

> What environment are you using that: - Has access to Youtube - Can run Python code - Can’t run JS code Nothing specific, just tend to run tools in restricted VMs where things are whitelisted and it's pretty much as locked down as it can be. It can run whatever I want it to run, including JS, and as the logs in my previous comment shows, it is in fact running both Python and JS, and has access to YouTube, otherwise it wouldn't have worked :) I tend to have the rule of "least possible privileges" so most stuff I run like that has to be "prepped" basically, especially things that does network requests sometimes (updating the solver in this case), just a matter of packaging it before I run it, so it's not the end of the world. No weird OS or architecture here, just good ol' Linux. > IMO it seems like it should safe to trust code being serve

Seems its already in Arch's repositories, and seems to work, just add another flag to the invocation: yt-dlp --cookies-from-browser firefox --remote-components ejs:github -f "bestvideo[ext=mp4]+bestaudio[ext=m4a]/best[ext=mp4]/best" 'https://www.youtube.com/watch?v=XXX' It is downloading a solver at runtime, took maybe half a second in total, downloads are starting way faster than before it seems to me. [youtube] [jsc:deno] Solving JS challenges using deno [youtube] [jsc:deno] Downloading challenge solver lib script from https://github.com/yt-dlp/ejs/releases/download/0.3.1/yt.solver.lib.min.js It would be great if we could download the solver manually with a separate command, before running the download command, as I'm probably not alone in running yt-dlp in a restricted environment, and being able to package it up togethe
