Question

Hello,
I'm trying to decrypt the signature for this player using jsinterepert code:
https://youtube.com//s/player/530216c1/player-plasma-ias-tablet-en_US.vflset/base.js

I believe jsInterpert is failing at some point, the function is being matched in the regex but it won't interpret the expression:
"""
nk=function(a){a=a.split("");var b=[-1087616052,1003077850,function(c,d){d=(d%c.length+c.length)%c.length;c.splice(-d).reverse().forEach(function(e){c.unshift(e)})},
"""
I wonder if it's possible to actually add this player function to be interpreted using the code in here.

Many thanks
