28db7fce02 slow but accurate integer dct from IJG (should be ok with the LGPL as the old DCT is the fast integer DCT from IJG) 
per context DCT selection

39825f315f * reimplemented remaing avg_ pixel functions 
* modified PAVGB mmx macro to select mmx register with FE constant

fca0f0e59f * removed MANGLE from macros for setting constants 
* using MOVQ_WONE/MOVQ_BFE as two instruction instead of static memory value access
  as its always faster
* PAVGB_MMX macro is using now mm6 -> mm7 is unmodified
* replaced original pixels_xy2_mmx with new faster and equal implementation
* replaced usage of mm7 for other then ZERO contstant in _rnd & _avg file with mm6

6aa6ea8e11 * reenabled original xy2 put routine - rounding error is really bad with 
the new code
* added PAVGP macros for parallel processing to safe few more cycles on
  celerons

91abb473fb * code with new PAVGB for MMX only CPU splited into separate file 
and being compiled in the same way as _avg.h
* PAVG_MMX macros accept also output parameter
* implemented faster put_pixels_xy2, but it has slightly smaller precission.
  But there is not visible difference in the image quality - might be eventualy
  easily switched back (#if 0 #endif)- please check

def60345ad * new mmx code - based upon http://aggregate.org/MAGIC 
for now it's rather sneak preview (new functions are nearly 100% faster)

fbdedc1704 * always baling even though it seems to produce sometime worse 
results then for -fPIC compilation - don't ask me why...

9dbcbd92e8 fixed mpeg4 time stuff on encoding 
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? ;)

d6a4c0b111 * some modifications to allow gcc to compile same code for -fPIC 
- introduced MOVQ_WONE, MOVQ_WTWO
* unrolled put_pixels_clamped_mmx
* added .baling where the jump address would be compiled on odd address
* added some testing code to disable all these routines (for time measurement)
