Youtube-dl is a program that can be used only from a terminal, without any graphical interface, which allows you to download videos from Youtube and other websites with a simple text command.
SUPPORTED WEBSITES, from which it is possible to download videos via youtube-dl there are so many: YouTube, YouTube playlist, Yahoo! screen, DepositFiles, vimeo, MTV, XNXX, CollegeHumor, YouPorn, Veoh; the complete list can be viewed by typing from the terminal:
youtube-dl --list-extractors
obviously we will have to first install youtube-dl with the command:
sudo apt-get install youtube-dl
and then update it to thelatest version:
sudo youtube-dl -U
to download the video simply type in the terminal:
youtube-dl [video-to-download-URL]
we will find the video downloaded in our home, in .flv format
to define another video format, we will have to add the -f option to the youtube-dl command, followed by the corresponding number of the format:
youtube-dl -f [n ° format] [url-video]
the numbers corresponding to the chosen video format can be viewed in This Page, if for example we wanted to download the previous video in .mp4 format:
we find the number corresponding to the mp4 format, which in this specific case is the 22:
at this point we give the following command:
youtube-dl -f 22 http://www.youtube.com/watch?v=nkvlZMs6YqQ
the video will be downloaded in .mp4 format, for further information on the youtube-dl functions consult the documentation directly from the terminal with:
