Having same issue with this video URL http://youtube.com/watch?v=q2gICJFG6uw
Error : ==== Failed to get deciphers function ====
If 'enable_youtube_decipher_signature' = false then it shows 0B size and url without signature .
This problem occurs with most of the videos . Signature is not including inside the video but it is resulting in an array seprated from url like this

array (
'itag' => '43',
's' => '3232BA30453D8D266CB70B41F69B3A04DD2EB2A6F1.65EB176B2E420E46260BCC046463D9338A4F30831',

Is it only the cypher signature feature that's broken? I've never actually used that so I don't have good test cases.

@hzlooker @SnappaGuy @Lucky420 @jswails Is the problem you are having with the cypher signature error message that @harisnaeemofficial quotes above, or are you having other problems?

My assumption is that YouTube has rolled out changes to their cypher signature algorithm and until someone develops code to handle those new signatures (or ports it from one of the other packages) this will continue to fail.
