Who here has a Youtube-DL compile for WinXP?

This won't make you happy, but in my case is true that if I don't use quickjs, which I usually don't, the m3u8 formats are not listed, what I don't care much anyway, but that is what happens to me.

There is a difference in the video information retrieval, when not using the JS runtime, it downloads only the adroind JSON, but when using the JS runtime downloads the safari player JSON, the player Javascript and then downloads the m3u8.

But I don't know why this happens to me and not to you.

@johk

What you describe is perfectly normal now ; when one a) doesn't pass YT logged-in cookies b) doesn't enable a JS runtime, then ONLY the android_sdkless (ANDR-S) formats are being available; these don't include any HLS (m3u8) formats (BTW, the ANDR-S client doesn't work at all with YT logged-in cookies).

OTOH, the web_safari (WEB-S) client formats (of the HLS type, only) were, up until a week ago, also accessible under the above scenario; but now, because Google  have put them behind an n/sig JS challenge, they do require a JS runtime (e.g. quickjs) to be enabled for them to become available to yt-dlp.

The IOS HLS formats are (at this time at least, can't vouch for how much longer ) accessible without a JS runtime, but they have to be explicitly requested with the 

--extractor-args "youtube:player_client=ios;formats=missing_pot"

argument; this will also yield the https IOS formats, which are inaccessible without also providing a PO Token  ...

Hope it's clear to you now  ...

[johk]

yes, clear as water, sorry.

As I go the default way, I was really missing something

FFmpeg update.

XP:  shared  static  libfdk-aac

VISTAx86:  shared  static  libfdk-aac

@autodidact

Thank you for the FFmpeg builds. 

Now, would you be so kind to update OpenSSL 64-bit dll's to 3.6.1? 🙏

This is an important security update.

Thanks again! 

Working fine as far as I can see:

Most sadly, another end is pretty close  : 

https://github.com/yt-dlp/yt-dlp/issues/15712

Soon-ish, no more youtube downloads without a JS runtime enabled (and without passing logged-in YT cookies, only the WEB-S client (HLS) formats would become available - these do require the JS runtime, though) ... 

 

[VistaLover]

FTR, issue #15712 isn't constantly giving me 403s here (but it often does  ), so, at this point, I'll say that the avc1 ANDR-S formats are unreliable (YMMV):
