YouTube signature decipher with an working example for VB.Net

Question

I know there are many projects and I could use them. But I really want to get it running without dependencies in my VB.Net project.

So what I try to do is creating

Answer 1

Sorry people but the old "html5player.js" player no longer works, it's 404 and the Url you need now looks more like https://s.ytimg.com/yts/jsbin/player-en_US-vfl_cdzrt/base.js

you starter for six is finding a function that look like this in the javascript

xr=function(a)
{
a=a.split("");
wr.rF(a,54);
wr.fs(a,75);
wr.N0(a,1);
wr.rF(a,52);
wr.N0(a,3);
wr.fs(a,31);
wr.rF(a,16);
wr.fs(a,38);
return a.join("")
}

After that i get a bit lost because the code for the wr function looks just the same and i cannot find the code for the swap,replace,split functions like Youtube have used in the past.

wr=function(a)
{
a=a.split("");
wr.rF(a,54);
wr.fs(a,75);
wr.N0(a,1);
wr.rF(a,52);
wr.N0(a,3);
wr.fs(a,31);
wr.rF(a,16);
wr.fs(a,38);
return a.join("")
}

wr.N0 i think looks like this but the javascript then goes above my pay-grade for me to follow what is going on.

N0=function(a,b){Tb(nga,b)&&tm(H_(a),a.O,b,a.Pq,a)}
