ERROR: Unable to extract title

[AlexandruM]

So I tried to use this command to download the default favorites playlist (not sure if this is the reason why it can't find the title).

youtube-dl -cit --verbose --max-quality FORMAT --extract-audio --audio-format mp3 http://www.youtube.com/playlist?list=FLxrNE9Dgtg_F7NgkcxmFSZg

and got the following error:

Is there something I can do? Or is this because of yet another YouTube UI update?

[phihag]

You are using an outdated version of youtube-dl. YouTube changed their playlist UI in May 2014, and the last change to their player dates 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.

I did install the youtube-dl from the Linux Mint GUI package manager.
When I do try the -U command I get:

sudo youtube-dl -U
youtube-dl is up-to-date (2014.08.05)

I'll try to remove the app from the package manager and try a manual install again.

It worked.

For Linux Mint 17 at least this should do it:

sudo curl https://yt-dl.org/downloads/2014.08.05/youtube-dl -o /usr/bin/youtube-dl (had to delete /local/).

It's downloading as we speak.

Thank you for the help.
