Dirac updates
BBC research has been updating the Dirac specification again. My work wasn’t updated after August, so I had to go over the changes in the specification. After some frustration and hard work, it’s updated again. The only thing left is adding the new interpolation filter. This should result in a performance gain, because this filter is simpler and can be done using shifts, instead of multiplications 
Now I will focus on some cleanups and optimizations. Now I have some time for this because of Christmas holidays (2 weeks). I have several in mind and I will post the performance gain to my blog after the optimizations are committed.
