When I try to download an age-unrated film Volga-Volga, I get "no known formats" error. Same for HTTP, same for other URLs for the film. If I log in and confirm, that I wish to see the film, I can watch it. The output with "-v" switch (I replaced login and password with "user" and "password") is below:

$ youtube-dl -F -t 'https://www.youtube.com/watch?v=wUnZqtcrOlI&wide=1&oref=https%3A%2F%2Faccounts.google.com%2FServiceLoginAuth&has_verified=1' -u user -p password
