pix_abs mmx2 isnt bit-exact ...

  • reimplemented remaing avg_ pixel functions
  • modified PAVGB mmx macro to select mmx register with FE constant

  • 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...

  • 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

  • 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...

  • baling 8 seems to have the same speed

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

Originally committed as revision 573 to svn://svn.ffmpeg.org/ffmpeg/trunk

  • cleanup for put_pixels_mmx

  • somewhat more advanced test suit for dsp code - for now i386 only
    cd test ; make dsptest ; ./dsptest

  • added simple test main - see comments about how to
    compile - should be probably made as a regression test

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)...

  • 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)...
