[XviD-devel] [CVS commit] devapi4 -- Big levels handling in trellis

[Edouard Gomez]

I noticed no problem during my tests. Let's see if someone else find
one.

    Summary:
      Big level handling in trellis.
    Revision:
      xvidcore--devapi4--1.0--patch-109
 
    Trellis was treating big levels exactly the same way as lower ones.
    In some cases, trellis was doing wild optimizations favoring a 0
    because the distortion introduced by that big coeff change was acceptable.
    But visually this could result in some nasty blocks with wrong
    chroma information or similar brutal changes in other planes as well.
     
    Skal added big levels handling where trellis just tries to minimize
    the cost varying the run value only. No level modification is done
    anymore.
