more correct EPZS implementation
much faster halfpel ME
simplifications / reducing duplicate code
4MV in LQ mode
Originally committed as revision 641 to svn://svn.ffmpeg.org/ffmpeg/trunk
- Added real_pict_num to AVCodecContext, it represent the number of the
previous encoded frame, usefull when coding with B frames.
- Warning fix in motion_est.c
Originally committed as revision 484 to svn://svn.ffmpeg.org/ffmpeg/trunk
mpeg4 b-frame enoding support
removed old, out-commented ratecontrol
reuse motion compensation code between encoding & decoding
prefix newly added global functions with ff_ to reduce namespace polution
b-frame ME (unfinished, but working)
added some comments to mpegvideo.h
do MC on encoding only once if possible
bugs? ;)

- EPZS ME algo used by default.
- HQ flag activated for ffmpeg.
- Cosmetics ...
Originally committed as revision 398 to svn://svn.ffmpeg.org/ffmpeg/trunk
SAD functions rewritten (8x8 support & MMX2 optimizations)
HQ inter/intra decission
msmpeg4 encoding bugfix (MV where too long)
Originally committed as revision 362 to svn://svn.ffmpeg.org/ffmpeg/trunk
20l (first frame of a gop could be a p-frame sometimes)
add hq flag to MpegEncContext
Originally committed as revision 356 to svn://svn.ffmpeg.org/ffmpeg/trunk
experimental (& faster) motion estimation
squished a dirty uninitialized var bug
mpeg1 fcode>1 support
Originally committed as revision 349 to svn://svn.ffmpeg.org/ffmpeg/trunk
unlimited mv search range
minor bugfix in the mpeg4 header parser
reset picture in gop counter if scene change is detected
Originally committed as revision 344 to svn://svn.ffmpeg.org/ffmpeg/trunk
DCT/Quantization is done after we have calculated all the MV of the picture.
- This is the preamble for a better bit rate control.
