"huffyuv" is compatible with the official version
"ffvhuff" contains our improvements

-corrected wrong value in mv data
-set correct mb_type after adjusting index
-don't use H263 loop filter when the loop filter flag is set but when
using the H261 encoder
-use the same unquantizer as H263 (which is optimized btw)
-removed unused members in H261Context

regression test checksum update by me

finetune bit/distortion weighting factor used in motion estimation, the old coeffs where finetuned relative to incorrect mv_penalty tables which where then fixed later but the coeffs where not
this _may_ fix the long standing blocking artifacts, but may also introduce mudding artefacts theoretically, so please tell us if u stumble across any so we can either fix them or export this variable so the user can change it

fixes the random dts/pts during encoding
asf preroll fix
no more initial zero frames for b frame encoding
mpeg-es dts during demuxing fixed
.ffm timestamp scale fixed, ffm is still broken though

note, dont take the PSNR/stddev values serious, they are caused by a bug in ffmpeg.c which drops one frame before the last frame during encoding with b frames

multithreaded/SMP encoding for MPEG1/MPEG2/MPEG4/H263
all pthread specific code is in pthread.c
to try it, run configure --enable-pthreads and ffmpeg ... -threads <num>
the internal thread API is a simple AVCodecContext.execute() callback which executes a given function pointer with different arguments and returns after finishing all, that way no mutexes or other thread-mess is needed outside pthread.c

function moved to dspcontext
mmx&mmx2 optimized
change SSE -> SAD as default (better quality)
vbv buffer size command line option in kbyte
Originally committed as revision 2669 to svn://svn.ffmpeg.org/ffmpeg/trunk
interlaced mpeg2 encoding
P & B frames
rate distored interlaced mb decission
alternate scantable support
4mv encoding fixes (thats also why the regression tests change)
passing height to most dsp functions
interlaced mpeg4 encoding (no direct mode MBs yet)
various related cleanups
disabled old motion estimaton algorithms (log, full, ...) they will either be fixed or removed
