Error downloading Vevo videos from YouTube with signature length 87

[Baqan]

Hi,

I have problems when I try to download Vevo videos from YouTube since minutes ago. Apparently, the problem is with Vevo videos with signature length 87 (maybe YouTube has changed the algorithm for this length again).

I'll wait for news and feedback. Thank in advance for your hard work as always.

python:
s[4:23] + s[86] + s[24:85]

javascript:
s.slice(4, 23).join('') + s[86] + s.slice(24, 85).join('')

Gotta find a better algo to do this...

@patrickslin Your algorithm for signature length 87 has been tested and it works. Big thank you! Good work!

Question, I updated youtube.py with the following changes

    elif len(s) == 87:
        return s[4:23] + s[86] + s[24:85]

I am not sure if this is all that I need to do but it's still not downloading my file??
