Please run youtube-dl --version to make sure you are using a halfway up-to-date version of youtube-dl. Since web services are often changing, we recommend the newest version (2014.09.14.3 as of writing), but you'll need at least 2014.05.25 for some YouTube videos, since YouTube changed their API on June 25th, 2014. It looks like you used a package manager such as apt-get to install youtube-dl. Please contact the Linux Mint support and request a not-totally-outdated version of the youtube-dl package. (Sorry, since we are not affilliated with Linux Mint, we cannot change what they are distributing)
Alternatively, uninstall the youtube-dl package and follow our manual installation instructions. In a pinch, this should do if you used apt-get before to install youtube-dl:

sudo apt-get remove -y youtube-dl
sudo wget https://yt-dl.org/latest/youtube-dl -O /usr/local/bin/youtube-dl
sudo chmod a+x /usr/local/bin/youtube-dl
hash -r
