i have seen that there is a new option there i can add site credentials for the extractor engine.
Can i enter here the credentials from chaturbate and then how i must do this?
Chaturbate does not require credentials to extract stream details from it so adding your credentials wont do anything.
How ever for sites that do (for example to access youtube.com age restricted videos you need to login)
Settings > Internet Downloads > Advanced > Extractor Logins
Under site credentials add youtube.com as the url and your username and password for youtube and click the + to add it to the list.
