ERROR: Automatic signature extraction failed:

[t0nym]

This was working last week; just upgraded to youtube-dl_2014.06.19-1... and since to 2014.07.15-1 (as per research) - getting the above error. Even with URL's that worked back then.
Further updated from 2014.06.19-1 as had "encryption" issues; research strongly suggested an update would correct issue.

Basically, have updated a number of packages - not really sure this is the issue (except python, of course) - I'll be working to get back software versions as was in the meanwhile.

Hopefully, the above is sufficient to assist in my enquiry. BTW - preceding with "sudo" also gives same response.

Your assistance would be much appreciated on this issue - pls do not hesitate should you require any further information.

First of all, don't run youtube-dl with sudo, unless you are updating it. While we are not aware of any vulnerabilities and reasonably confident that there are none, youtube-dl still communicates with online services. Just run it without sudo.

You are using an outdated version of youtube-dl. YouTube changed their player the day before yesterday, 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 (most likely either 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.

Many thanx for your reply.

Ran as "sudo" in reponse to research outside of your site - issue was
always initiated as self.

Using version 2014.07.25 did the do.

Once again, many thanx
