Michael Niedermayer	50eb9cbc44	idct_permutation_type variable, so the permutation type can quickly be identified Originally committed as revision 1071 to svn://svn.ffmpeg.org/ffmpeg/trunk	22 years ago

Michael Niedermayer	084c726ba3	pix_sum16_mmx() Originally committed as revision 961 to svn://svn.ffmpeg.org/ffmpeg/trunk	22 years ago
Arpi	3f09f52adf	fdct_mmx -> ff_fdct_mmx (renamed to avoid namespace conflict with xvid) [found by Kim Minh Kaplan] Originally committed as revision 960 to svn://svn.ffmpeg.org/ffmpeg/trunk	22 years ago
Michael Niedermayer	b318477992	put/avg_pixels16 fixing 2 small qpel bugs Originally committed as revision 915 to svn://svn.ffmpeg.org/ffmpeg/trunk	23 years ago
Michael Niedermayer	1a684b3d53	fixing encoding at high QPs (was broken after the dct accuracy increase due to too small inverse table) Originally committed as revision 901 to svn://svn.ffmpeg.org/ffmpeg/trunk	23 years ago
Michael Niedermayer	ad324c9351	dct cleanup more accurate mmx dct (dont discard bits for fun) fixing mmx quantizer bug for qscale%2==1 (bias was slightly wrong) Originally committed as revision 895 to svn://svn.ffmpeg.org/ffmpeg/trunk	23 years ago
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
Dominik Mierzejewski	0778718635	warning patch by (Dominik Mierzejewski <dominik at rangers dot eu dot org>) Originally committed as revision 872 to svn://svn.ffmpeg.org/ffmpeg/trunk	23 years ago
Michael Niedermayer	9f36153415	dont trash mm0, its still used in the next iteration of the loop (fixes strange horizontal lines on some blocks in b frames on mmx only cpus) Originally committed as revision 855 to svn://svn.ffmpeg.org/ffmpeg/trunk	23 years ago
Michael Niedermayer	87f8cab45b	mpeg4 mpeg quantizer encoding Originally committed as revision 844 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	d3cd07425a	* implemented remaing avg_ pixel functions (these are not used offen) Originally committed as revision 656 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	ff9657069a	* using unrolled loops seems to help to MMX Celerons * calculating average in parallel to use two MMX units * disabled xy2 put code - it's producing rouding errors Originally committed as revision 626 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	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	a213d66486	* fix for -fPIC compilation - compiles with 2.95.2 as well - any other compiler shows any problem here ?? Originally committed as revision 563 to svn://svn.ffmpeg.org/ffmpeg/trunk	23 years ago

Juanjo	ef5b1b5a7e	- Advanced Intra Coding (AIC) support for H.263+ encoder, just DC by now. - Bug fix H.263+ AIC tables. - Warning fixes. Originally committed as revision 431 to svn://svn.ffmpeg.org/ffmpeg/trunk	23 years ago
Michael Niedermayer	d7e9533aa0	fixed msmpeg4 infinite loop if buggy stream rewrote quantizer fixed bias (+10% compression/quality for h263 like codecs) qscale=1 support mpeg1 intra frames looks far less blocky added codec_id field Originally committed as revision 423 to svn://svn.ffmpeg.org/ffmpeg/trunk	23 years ago
