Any youtube restricted content which needs logging in will not download. (Or login fails?)

And I have found a solution. It was already possible, just not explained well.

For anyone wanting to know:

1. Get the chrome extension https://chrome.google.com/webstore/detail/get-cookiestxt/bgaddhkoddajcdgocldbbfleckgcbcid?hl=en
2. Go to https://www.youtube.com/ & login with your account. Grab the cookie txt file.
3. Go to https://myaccount.google.com/ & login with your account. Grab the cookie txt file.
4. Combine both into a txt, making sure to have the following at the top of the txt file (Without the ` ):

`# Netscape HTTP Cookie File
`# This file is generated by youtube-dl.  Do not edit.

5. In YDL-UI when you want to download a new video: a) Un-select basic mode b) Go to 'Workarounds' tab c) Tick 'Cookies:' and link to the cookies file. d) Tick 'Username' under 'Authentication' and put in login details.

That is the main solution that I know of. I don't think you need to include step 3 or add your login details. Just the cookies from YouTube should be enough.
