dies with "KeyError: 'sig'"

[Gumnos]

Trying to pull down Ok Go's Here It Goes Again using the latest master branch from git (0526e4f) on Debian Stable, but I got the traceback below. It continues to work well for other Youtube URLs.

tim@bigbox$ ~/bin/downloads/youtube-dl/youtube-dl --get-url --prefer-free-formats http://www.youtube.com/watch?v=dTAAsCNK7RA

0526e4f is ancient, why do you think it would be the latest commit? Can you post the entire input and output of all git commands you used?

Gaa, my apologies. I did a git fetch, but forgot to merge/pull. Bone-headed user mistake. Sorry for the noise. After a "git pull", 0577177 runs without a traceback, but does complain about encryption issues on the same video:

Is youtube-dl supposed to be able to handle these encrypted videos too? (If not, I can resign myself to going without, just hoped to pull it locally to save bandwidth from our preschooler wanting to repeatedly watch it)

[phihag]

Yes, youtube-dl handles these just fine. However, youtube changes the signature, and we haven't integrated a system to dynamically fetch that yet. Can you try to pull again, and then give the output with --verbose in the command line?

[Gumnos]

Here's the output from cd ~/bin/downloads/youtube-dl/; git pull; ./youtube-dl --verbose --prefer-free-formats http://www.youtube.com/watch?v=dTAAsCNK7RA which now gives a 403 Forbidden:

It's working fine with version 2013.08.21.

Confirmed working here. Thanks!
