Michael Niedermayer	ab00685a75	bugfix Originally committed as revision 636 to svn://svn.ffmpeg.org/ffmpeg/trunk	23 years ago
Fabrice Bellard	8155233413	fixed layer1/2 overflow if very loud sound - fixed broken free format decoding to pass all mpeg audio standard decoding tests (please avoid patching the parser without having all test streams available - contact me if necessary) Originally committed as revision 634 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	541027e26a	* cosmetic minor change Originally committed as revision 622 to svn://svn.ffmpeg.org/ffmpeg/trunk	23 years ago

Zdenek Kabelac	e9c0a38ff0	* optimized avg_* functions (except xy2) * minor speedup for put_pixels_x2 & cleanup Originally committed as revision 619 to svn://svn.ffmpeg.org/ffmpeg/trunk	23 years ago
Zdenek Kabelac	cd4af68ad5	* started to cleanup name clashes for onetime compilation Originally committed as revision 617 to svn://svn.ffmpeg.org/ffmpeg/trunk	23 years ago
Zdenek Kabelac	c0eb0bb717	* more PIC friendly and faster code Originally committed as revision 616 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
Zdenek Kabelac	8758f7e43c	* for this moment bswap.h included ahead of HAVE_AV_CONFIG_H check as its functionality is used even in those parts which are being compiled without this flag - generaly this would require more complicated cleanup patch - for now leaving for the main author Originally committed as revision 614 to svn://svn.ffmpeg.org/ffmpeg/trunk	23 years ago
Zdenek Kabelac	e5f3d22d35	* undefine local defines when they are no longer needed Originally committed as revision 612 to svn://svn.ffmpeg.org/ffmpeg/trunk	23 years ago
Zdenek Kabelac	f0ca2e1b0a	* compatibilized declaration with its original definition (though I'm not sure which one is correct - but they should match) Originally committed as revision 610 to svn://svn.ffmpeg.org/ffmpeg/trunk	23 years ago
Zdenek Kabelac	30eb039652	* avoids double inclusion of this header (how about making all headers in ffmpeg working this way ?) Originally committed as revision 609 to svn://svn.ffmpeg.org/ffmpeg/trunk	23 years ago
Fabrice Bellard	74fc99894b	don't use inttypes.h - use inline function for bswap_64() Originally committed as revision 608 to svn://svn.ffmpeg.org/ffmpeg/trunk	23 years ago

Philip Gladstone	935cdf0902	Add an av_abort macro that aborts, but also prints out the location of the abort. Helps track down bugs. Originally committed as revision 576 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	ba0420d83e	using 1 operand less and slightly faster put_pixels_y2 Originally committed as revision 564 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
Zdenek Kabelac	d7d267dfe0	* minor cleanup Originally committed as revision 562 to svn://svn.ffmpeg.org/ffmpeg/trunk	23 years ago
Michael Niedermayer	92ba5ffbb5	workaround dc_scale bug in old ffmpeg msmpeg4v3 encoder (set workaround_bugs=1 for this) Originally committed as revision 561 to svn://svn.ffmpeg.org/ffmpeg/trunk	23 years ago
Zdenek Kabelac	ddad77fade	* oops - these are the midnight commits... removed -fPIC used for testing compilability Originally committed as revision 560 to svn://svn.ffmpeg.org/ffmpeg/trunk	23 years ago
Zdenek Kabelac	c77b16ddba	* restored previous behaviour for this moment users are supposed to supply proper SCR_PATH however Originally committed as revision 559 to svn://svn.ffmpeg.org/ffmpeg/trunk	23 years ago
