Field interlaced decoding, contributed by Christoph Kuehnel
decoder.c
=========
- Some new defines for DIV
- <decoder_mb_decode> modified: had wrong address offsets for interlaced
- <decoder_mbinter_field> = new function for interlaced
- <get_motion_vector_interlaced> = new function for interlaced motion vector prediction
- <decoder_pframe> modified so that it differs between frame and field prediction
global.h
========
- For field motion prediction MACORBLOCK has new member that is the average of
field1 and field2 motion vector = <mvs_avg>
xvid.c
======
- For field predicted macroblocks we need new field oriented transfer functions.
For colour calculations they may only process 4 lines (one field from the colour
macroblock that is 8x8). So I introduced 4 new function pointers:
<transfer8x4_copy, interpolate8x4_ ...)
mbcoding.c
==========
- _DEBUG code; index is checked against 64
interpolate8x8.[c,h,asm]
===========================
- New 8x4 functions
mbpredicition.[c,h]
===============
- New function <get_pmv2_interlaced> for interlaced prediciton according to spec
mem_transfer.[c,h,asm]
==============
- New 8x4 function

Removed this annoying \n from DPRINTF output. DPRINTF behaves
now like usual printf.
Just for fun, i decided to exercice my regexp skills:
for i in `find . -name "*.c"` ; do
sed s/'\(DPRINTF(XVID_DEBUG.*\)"\([^"]\+[^\\][^n]\)"\(.*\)$'/'\1"\2\\n"\3'/g $i > $i.tmp;
mv $i.tmp $i
done
Nice isn't it ? It just adds a \n to every DPRINTF call that
was relying on old behavior (automatic trailing \n).

* dynamic bvop decision stats bug fixed
* added runtime debug level option. this only only activated when _DEBUG is defined.
level is specified globaly, via "xvid_glb_init_t.debug" and XVID_DEBUG_xxx defines.
references to previous DPRINTF_LEVEL_xxx's have been replaced throughout libxvidcore
* futher bitrate zone fixes for plugin_2pass2.c
* removed old ratecontrol.c from msvc project
* xvid_encraw.c specifc:
* added "-max_key_interval integer" option
* renamed -debug to -vop_debug
* added "-debug integer" option, which sets xvid_gbl_init_t.debug field
* s/length/len/ status line
* vfw specific:
* zone/bitrate typos fixed ("you eediot")
* renamed "debug" regkey to "vop_debug"
* added "debug" regeky and textbox which sets xvid_gbl_init_t.debug field

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 ?

Modified SKIP mb behaviour for Pframes when Bframes are active: Check if
intermediate B-block can be skipped, too. Check for SKIP is now done
in encode_pframe(), not in MBCoding().

Added #ifdef _DISABLE_SKIP in MBCoding(). If this is defined, there
will be __no skipped macroblocks__ in P-frames!
This is of course bad (bigger files), but it's needed for clean B-frame
encoding until we have a workaround for the SKIP-flaw in the standard. :-(

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)
Win32 users should give feedback.
