If anyone faces this issue, please upgrade the version of youtube-dl
I was able to resolve this issue by upgrading Youtube-dl. The current version in Trusty is not backported I guess

sudo aptitude show youtube-dl
Package: youtube-dl
State: installed
Automatically installed: no
Version: 2014.05.19-1webupd8trusty0

Below is the link I used to upgrade it, from webupd8.
