Zdenek Kabelac	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 Originally committed as revision 624 to svn://svn.ffmpeg.org/ffmpeg/trunk	23 years ago
Zdenek Kabelac	def60345ad	* new mmx code - based upon http://aggregate.org/MAGIC for now it's rather sneak preview (new functions are nearly 100% faster) Originally committed as revision 623 to svn://svn.ffmpeg.org/ffmpeg/trunk	23 years ago
Zdenek Kabelac	5f6230016a	* removed TESTCPU_MAIN - not needed for testing Originally committed as revision 615 to svn://svn.ffmpeg.org/ffmpeg/trunk	23 years ago
Fabrice Bellard	ff4ec49e64	license/copyright change Originally committed as revision 599 to svn://svn.ffmpeg.org/ffmpeg/trunk	23 years ago
Zdenek Kabelac	52af45ad77	* baling 8 seems to have the same speed Originally committed as revision 575 to svn://svn.ffmpeg.org/ffmpeg/trunk	23 years ago
Zdenek Kabelac	fbdedc1704	* 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	23 years ago
Zdenek Kabelac	31ddcf9851	* cleanup for put_pixels_mmx Originally committed as revision 572 to svn://svn.ffmpeg.org/ffmpeg/trunk	23 years ago
Zdenek Kabelac	ec9a41f57d	* somewhat more advanced test suit for dsp code - for now i386 only cd test ; make dsptest ; ./dsptest Originally committed as revision 568 to svn://svn.ffmpeg.org/ffmpeg/trunk	23 years ago
Zdenek Kabelac	6efad6fd85	* align the source initialy address Originally committed as revision 567 to svn://svn.ffmpeg.org/ffmpeg/trunk	23 years ago
Zdenek Kabelac	dcb9cd4b81	* added simple test main - see comments about how to compile - should be probably made as a regression test Originally committed as revision 565 to svn://svn.ffmpeg.org/ffmpeg/trunk	23 years ago

Michael Niedermayer	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? ;) Originally committed as revision 403 to svn://svn.ffmpeg.org/ffmpeg/trunk	23 years ago

Michael Niedermayer	ba6802debf	4MV motion estimation (not finished yet) 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	23 years ago
Zdenek Kabelac	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) Originally committed as revision 308 to svn://svn.ffmpeg.org/ffmpeg/trunk	23 years ago
