You are using an outdated version of youtube-dl, you have to update it.

Is it not pushed to the official arch linux repo's yet? I used pacman to install youtube-dl and it's reporting that it's up to date.

From the FAQ entry I linked:

Unfortunately, there is nothing we youtube-dl developers can do if your distribution serves a really outdated version. You can (and should) complain to your distribution in their bugtracker or support forum.

You can still update it manually, but probably pacman will stop tracking it.

Ah, gotcha. Thanks very much!
