Yt-dlp: External JavaScript runtime now required for full YouTube support

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.

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 together with the solver before runtime would let me avoid lessening the restrictions for that environment. Not a huge issue though, happy in general the start of downloads seems much faster now.

Glad to hear it’s faster now!

YouTube barely works in a full-on browser these days, props to the team that keeps it accessible via a Python script!

Do you use Firefox on Linux, too? 4K Videos freeze so often for me, I don't even try watching them online, and always just download them with yt-dlp. It doesn't bother me enough to give Chrome a try, but maybe that'd make a difference.
