Ok, first the streamfab.log is needed.
Second, YT standard everyday videos work in SF.
The section on YT called Movies & TV needs the YT Movies & TV downloader, which is BROKEN.
The YT Movies and downloader are fixed now.
So any movie or show there won’t download. Some are for rent, and some are for buying.
I usually only do the movies with ads, which also, right now, don’t work.
So if it is standard YT videos, delete your streamfab.log and then try a YT video again, and if an issue occurs, then attach that newly created log to a post. It could be some videos; it could be something on your YT account or network.
The log may show that. I again just tried random standard YT videos, and they analyze and download fine.
The log should also show what videos, so others could try to see if it is certain videos not working or not.
Might be a location issue.
Also, with the streamfab.log, can you give more details, like if it is stuck analyzing or not downloading? Or if something important pops up, take a screenshot and upload that here. All this info will help those here point you to the problem.
If it’s premium YT content, then it can be harder for someone to help, as they would need access to the YT premium content. My personal opinion is to never pay for YT Premium. YT has enough money.
