Unable to download video with signature of size 84

[rbrito]

Hi.

I received a bug report in Debian that there were some problems downloading a video with signature length of 84. I uploaded a new version to the Debian repository and I still see it with version 2013.10.01:

Despite this, every other video that I tried so far has worked for me.

Thanks,

Just as some extra information, there's something that I had not yet seen: when I successively try to download the video above, the signature lengths vary a lot (e.g., some times, it has length 81, other times, 82, then 87, then my reported 84 and so on). Is this usual?

Seems like you have an old version, please update with option -U.

Also, I'm interested to see the decryption key (keeping that as fall back option). After updating, can you run with option --youtube-print-sig-code and post the key?

Thanks

It works with versions from 2013.10.01.1 and higher, in 2013.10.01 we introduced a bug (f10503d), which was fixed later in 44d4665.
I'm closing this, but if the problem persists, just comment and we will reopen it.
Thanks for the report.

About the signature length, it's completely normal, they use different lengths at the same time.
