This video in the browser requires flash but youtube-dl only seems to mention trying the HTML5 player.

This has been fixed in the last version (2014.07.15), run sudo youtube-dl -U to upgrade.

[parkerlreed]

Hmm ok thanks. Im on Arch and had just ran a system update yesterday.

[jaimeMF]

Probably they haven't updated to the new version in the Arch's package manager, you may want to contact the package maintainer.

[parkerlreed]

Heh it showed up today. :D Thanks for the help.
