tuning (low to high) D#, G#, C#, F#, A#, D# 
                 aka Eb, Ab, Db, Gb, Bb, Eb 
just tune the entire guitar down half a step 

I saw the video, and I can almost guarantee this is correct 

this is a very easy song with only about 2 riffs there are a  
few changes through the song, but they are all pretty minor. 

timing is not shown perfectly, just listen to the song 

intro: 
D#|---------------------------------------------------------- 
A#|-------7-----7--7--7--7------------------5--5--5--5--5--5- 
F#|-9-----9-----9--9--9--9------7-----7-----7--7--7--7--7--7- 
C#|-9-----9-----9--9--9--9------7-----7-----7--7--7--7--7--7- 
G#|-7-----7-----7--7--7--7------5-----5-----5--5--5--5--5--5- 
D#|--------------------------0------------------------------- 

D#|-------------------------------------------------------------- 
A#|-------------------------------------------------------------- 
F#|--------------------------------------6---5--5--5--6--------5- 
C#|-5-----5-----5--5--5--5--5--5--7---7--7---7--7--7--7--7--7--7- 
G#|-5-----5-----5--5--5--5--5--5--7---7--7---7--7--7--7--7--7--7- 
D#|-3-----3-----3--3--3--3--3--3--5---5--5---5--5--5--5--5--5--5- 

the verses are just simplified versions of that riff. 
sometimes he changes the power chords into full barre chords 
like in the intro.  He does this at random times though, so 
just improvise if you feel the urge.  Sometimes he doesnt play 
the open D# also, and he just slides from the first chord to the 
2nd 
D#|---------------------------------------------------------- 
A#|---------------------------------------------------------- 
F#|-9-----9-----9--9--9--9------7-----7-----7--7--7--7--7--7- 
C#|-9-----9-----9--9--9--9------7-----7-----7--7--7--7--7--7- 
G#|-7-----7-----7--7--7--7------5-----5-----5--5--5--5--5--5- 
D#|--------------------------0------------------------------- 

D#|-------------------------------------------------------------- 
A#|-------------------------------------------------------------- 
F#|-------------------------------------------------------------- 
C#|-5-----5-----5--5--5--5--5--5--7---7--7---7--7--7--7--7--7--7- 
G#|-5-----5-----5--5--5--5--5--5--7---7--7---7--7--7--7--7--7--7- 
D#|-3-----3-----3--3--3--3--3--3--5---5--5---5--5--5--5--5--5--5- 

the chorus uses the following chords, in this order.  it follows 
the exact same beat of the rest of the song 
D#|-0----3----2----0- 
A#|-0----3----3----0- 
F#|-1----0----2----2- 
C#|-2----0----0----2- 
G#|-2----x---------0- 
D#|-0----3----------- 

after the chorus, start the verse with an open D# 

the bridge is pretty much the same 
"All the times that I've cried, all this wasting, it's all inside..." 
the chords used here are: 
D#|-x----x----x----x- 
A#|-x----x----x----x- 
F#|-9----7----x----x- 
C#|-9----7----5----7- 
G#|-7----5----5----7- 
D#|-----------3----5-
