get rid off compiler warnings

improved decoder robustness upon resync markers in BVOP

fix for typo on pred mv init (thanks to Lasse Collin)

API change: signal fourcc to xvidcore

Bugfix:
- Added missing resync marker range check in decoder.c (reported by IBM X-Force. Thanks go to John McDonald and Christopher Valasek)
- return E_FAIL instead of S_FALSE upon XVID_ERR_MEMORY error in dshow frontend (reported by IBM X-Force. Thanks to John McDonald and Mark Dowd)

- small bug reported by Greg Handi

        fix for the visual_object_verid vs. video_object_layer_verid
        problem of 6.3.3, reported by Li Xiang (lixiang01 at gmail dot com)
        Thanks for report and test bitstreams!

- Initialize dec->bs_version to high value. Before it seemed unititalized for
  non XviD streams...

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

	encoder.c: simplify_time() optimized by Euclid.

	bitstream.c: write_video_packet_header() was buggy and
	kind of obfuscated, as noticed by Sigdrak at free.fr.

	from Edouard:

	gcc4 warning removal.
	- No executable shared objects installed
	  (Do not install the lib as executable. It's no use as the SO has no
 	   main symbol anyway, and the static lib is not runnable anyway.)
	- Statically link xvid_bench with libxvidcore.a
	- New autoconf garbage removal
	- Quotes in configure.in

xvidcore
========
* added XVID_GLOBAL_DIVX5_USERDATA global flag
* removed the bvop delay warning text ("warning: nothing to output), as this often confuses joe user.
* minor changed to closed gop image_printf statement: s/"DX50 BVOP->PVOP"/"CLOSED GOP BVOP->PVOP"
* additional comments for low_delay_default mode within decoder_decode()
* divx userdata string: s/DivX999b000/DivX503b1393. this has been suggested by dxn for improved hardware compatibility [nb: i dont have a hardware player to confirm this]
* vbv_peakrate constraint is ignored if <= 0

vfw frontend
============
* dxn profiles now confirm to "DivX Certified Profile Compatibility v1.1", February 2005. this document was provided by DivXNetworks, USA. when a dxn profile is selected, strict conformance is enabled:
  - force 1:1 picture aspect ratio
  - disable bframes if interlacing is enabled
  - force maximum of 1 consecutive bvops for the portable and ht profiles, 2 bvops for the hd profile
  - always write divx 5 userdata string to bitstream
  - force packed bitstream option
  - updated dxn vbv parameters
* added PROFILE_4MV flag. 4mv is now disabled for the dxn handheld profile.
* moved PROFILE_AS/PROFILE_ARTS/PROFILE_S to config.c
* profile[].max_bitrate now measured in bit/sec (not kbps)
* profile->level box: widgets are now greyed-out if they are not used.
* increase vertical size of profile drop down list.
* about box button: s/Dismiss/OK

Fix vector bound checking for bvops

make sure that MV is in range in b-frames too. prevents crashes with broken bitstream

Small cleanup (will ease future patches thanks to the unified add_residual pointer), no speedup at all

Fixes from my tree, especially the bvop ref block interpolation fix

Faster getcoeff + on the fly dequant

low_delay fix

DC clipping bug take #2

Commited fixes from my branch (timestamps in decoder, missing va_end calls, bad license header...

Wrong DC prediction fixed

won't crash if stream doesn't start with an i-vop

better MV clipping - does not break DX50 streams which have motion out of range

stats->type set to NOTHING by default
in some instances stats->type was not being set (namely lowdelay=1, packed=1, type=nvop).

xvidcore 1.0.0 rc3 merge back to HEAD

don't use comants to mark out pieces of code

prevents an ugly crash. we shouldn't read more bitstream than we have, ever

an ugly bug (by me), I wonder why noone noticed before

postprocessing changes

some quality improvements for postprocessing

* copyright fix(?)
* ending new lines missing (gcc)
* added $Id$ field

postprocessing (deblocking) code ported from Isibaar branch + speed-up

* Thread safe MPEG4 quantization functions.
  Cleaned up version of patch provided by Michael
   - fixed compiling problems on gcc
   - added const qualifiers every where it was possible to help C compiler
     optimization.
   - added the mpeg_quant_matrices param to all ASM function prototype
     in comments (even if it's not used, that shows we do it deliberatly)
   - forces m[intra][0][0] = 8, otherwise XviD could write invalid streams.
* Added real CRC computing in xvid_bench.c

Removed unused next_block vars

interpolate mode + qpel decoding fixed; MACROBLOCK->mb_type completely replaced by MB->mode

interlacing support for b-vops and s-vops

fix to mcsel/acpred bit reading (were swapped)

API changes

Activated simple_idct for MMX - Backward compatibility with bistream version 9 ensures the use of the standard idct_mmx function

Added legal header

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).

- fast b-frames
- dynamic qpel
- qpel asm code
- postprocessing

xvid_pluing_lumimasking added
xvid_encraw -lumimasking option added

sad values can be negative (Cristoph post scriptum to a mail in the dev maillist)

add some B-frame support

reworked vlc tables

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.

interlacing support - slow (MBDecideFieldDCT()), buggy (p-frames), incomplete (field motion prediction)
