Lennert Buytenhek	1565dabc1a	be less verbose patch by (Lennert Buytenhek <buytenh at math dot leidenuniv dot nl>) Originally committed as revision 889 to svn://svn.ffmpeg.org/ffmpeg/trunk	23 years ago
Michael Niedermayer	e7fce5e9fb	bitexact hack for the simple mmx idct Originally committed as revision 886 to svn://svn.ffmpeg.org/ffmpeg/trunk	23 years ago
Michael Niedermayer	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 Originally committed as revision 878 to svn://svn.ffmpeg.org/ffmpeg/trunk	23 years ago
Michael Niedermayer	4afeaec92f	pix_abs mmx2 isnt bit-exact ... Originally committed as revision 781 to svn://svn.ffmpeg.org/ffmpeg/trunk	23 years ago
Zdenek Kabelac	39825f315f	* reimplemented remaing avg_ pixel functions * modified PAVGB mmx macro to select mmx register with FE constant Originally committed as revision 657 to svn://svn.ffmpeg.org/ffmpeg/trunk	23 years ago
Zdenek Kabelac	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 Originally committed as revision 632 to svn://svn.ffmpeg.org/ffmpeg/trunk	23 years ago
Zdenek Kabelac	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 Originally committed as revision 625 to svn://svn.ffmpeg.org/ffmpeg/trunk	23 years ago
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
Fabrice Bellard	4f12a4976a	removed unused code Originally committed as revision 543 to svn://svn.ffmpeg.org/ffmpeg/trunk	23 years ago
Fabrice Bellard	61a4e8ae3b	removed debug function Originally committed as revision 519 to svn://svn.ffmpeg.org/ffmpeg/trunk	23 years ago
Michael Niedermayer	a7bd879798	shared lib support (req by kabi) ... Originally committed as revision 510 to svn://svn.ffmpeg.org/ffmpeg/trunk	23 years ago
Michael Niedermayer	607dce96c0	hopefully faster mmx2&3dnow MC Originally committed as revision 506 to svn://svn.ffmpeg.org/ffmpeg/trunk	23 years ago
Zdenek Kabelac	cd8e5f9637	* fixes problem with -funroll-loops and buggy gcc compiler Originally committed as revision 421 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	649c00c96d	sizeof(s->block) isnt 6462 anymore bugfix mpeg12 decoding optimization Originally committed as revision 364 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
Michael Niedermayer	f4470e0936	print cpu flags Originally committed as revision 248 to svn://svn.ffmpeg.org/ffmpeg/trunk	23 years ago
