2003-04-10 GMT Edouard Gomez <ed.gomez@free.fr> patch-14
Summary:
Removed all ABS() macros.
Revision:
xvidcore--devapi4--1.0--patch-14
All ABS macros have been replace with their stdlib.h/math.h
equivalent. This gives a 33% overall speedup for the plain C encoder,
while the ia32 one seems to suffer a small speed loss. However this
speed loss is very small and it seems it depends on the CPU type as
the abs/fabs usage is impacting badly on sad functions but impacting
well on interpolate functions ... weird inst'it ?

2003-03-10 00:36:15 GMT Edouard Gomez <ed.gomez@free.fr> patch-4
Summary:
Adds extended stats support even for bframes in xvidcore.
Revision:
xvidcore--devapi4--1.0--patch-4
This patch enables core extended stats support even for bframes. It
modifies the way the MBTransQuantBVOP function does its work. It used
to not dequant, idct the MB because bframes are never used as reference
frames. However if we want to compute stats, then we must perform these
inverse transformations.

Big patch, use it with care (tests done with GNU/Linux) :
- Trivial warnings in encoder.c line 282 ret1 = ret 2 = 0;
- Lot of "New line at end of file missing" warnings fixed (gcc3)
- All 2d arrays have been turned into 1d arrays
To force alignment of matrices on stack, use DECLARE_ALIGNED_MATRIX
(read portab.h)
