# the original webpage as well as el=info and el=embedded get_video_info
# requests report video unavailability due to geo restriction while

# due to YouTube measures against IP ranges of hosting providers.
# Working around by preferring the first succeeded video_info containing
# the token if no such video_info yet was found.
