You are using an outdated version of youtube-dl. YouTube changed their player on 2014-07-25, so you'll need at least youtube-dl version 2014.07.25 (or newer).

It looks like you installed youtube-dl with a package manager (something like apt-get, or pip). You can use that package manager to update youtube-dl (you may need to contact the package maintainer though, and request an update).

Alternatively, uninstall the youtube package and follow our manual installation instructions. From then on, you'll be able to update with sudo youtube-dl -U.

Thank you for the quick response. I did install it from Ubuntu, and the debian package is also at 2014-07-15.

I will remove the package, and install manually.

Thanks, again.
