Youtube not downloading "requested format is not available"

[Germania]

Hello @ Germania.

I did some testing on this Video: https://www.youtube.com/watch?v=gXQafIT2V_8

I opened SF and it wasn`t able to download. (Audio only as described by others)
I opened yt-dlp and loaded the same Video. I chosed the format without downloading via yt-dlp.
Then I went back to SF, wich was still open. Reanalyzed the Video. Now SF was able to download.
Since I don`t reboot my Computer, SF works fine, even if I close and reopen SF. (yt-dlp was closed)

First of all: Thanks for your good description

Nice find, even if I was unfortunately unable to recreate it with two attempts ..
.. and I can dl the video with old and current yt-dlp, but in SF only Audio offered.

> I don`t know if it is helpful to fix SF.

I've no contact to dev of SF, but I am pretty sure that the integration
of the latest yt-dlp change in SF will fix the problem with audio only.
This certainly has to do with the fixed issues:

Fix PhantomJS nsig fallback (#12728) by bashonly
Fix signature and nsig extraction for player 363db69b (#12725) by bashonly

while I see this with SF used old yt-dlp version:

Native nsig extraction failed: Trying with PhantomJS
nsig extraction failed: Some formats may be missing
