-       title, author and others. The information is stored in a dictionary

-       processes this information possibly downloading the video to the file

-       uploader:       Nickname of the video uploader.

-       youtube-dl to serve as the backend for a video search function, such
-       as the one in youtube2mp3.  They are only used when their respective
