Jason Garrett-Glaser	8a467b2d44	VP8: 30% faster idct_mb Take shortcuts based on statistically common situations. Add 4-at-a-time idct_dc function (mmx and sse2) since rows of 4 DC-only DCT blocks are common. TODO: tie this more directly into the MB mode, since the DC-level transform is only used for non-splitmv blocks? Originally committed as revision 24452 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Jason Garrett-Glaser	c25c776708	VP8: clear DCT blocks in iDCT instead of using clear_blocks. ~0.3% faster overall. Originally committed as revision 24448 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Ronald S. Bultje	dc5eec8085	Use pextrw for SSE4 mbedge filter result writing, speedup 5-10cycles on CPUs supporting it. Originally committed as revision 24437 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago

Jason Garrett-Glaser	8731dbd890	Eliminate one instruction in VP8 dc_add_sse4 Originally committed as revision 24405 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Jason Garrett-Glaser	7dd224a42d	Various VP8 x86 deblocking speedups SSSE3 versions, improve SSE2 versions a bit. SSE2/SSSE3 mbedge h functions are currently broken, so explicitly disable them. Originally committed as revision 24403 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Jason Garrett-Glaser	b8b231b5dc	Make mmx VP8 WHT faster Avoid pextrw, since it's slow on many older CPUs. Now it doesn't require mmxext either. Originally committed as revision 24397 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
David Conrad	af521abc28	Add header declarations for mmx/sse constants missing them Originally committed as revision 24381 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
David Conrad	c7eec58170	Move ff_pw_* from vc1dsp_mmx.c to dsputil_mmx.c Should fix compilation with icc and should help prevent any future duplicates Originally committed as revision 24380 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Ronald S. Bultje	e9e456d850	VP8 MBedge loopfilter MMX/MMX2/SSE2 functions for both luma (width=16) and chroma (width=8). Originally committed as revision 24378 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Ronald S. Bultje	268821e76e	Chroma (width=8) inner loopfilter MMX/MMX2/SSE2 for VP8 decoder. Originally committed as revision 24377 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Ronald S. Bultje	c60ed66dbe	Revert r24339 (it causes fate failures on x86-64) - I'll figure out what's wrong with it tomorrow or so, then re-submit. Originally committed as revision 24341 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Ronald S. Bultje	6526976f0c	Remove FF_MM_SSE2/3 flags for CPUs where this is generally not faster than regular MMX code. Examples of this are the Core1 CPU. Instead, set a new flag, FF_MM_SSE2/3SLOW, which can be checked for particular SSE2/3 functions that have been checked specifically on such CPUs and are actually faster than their MMX counterparts. In addition, use this flag to enable particular VP8 and LPC SSE2 functions that are faster than their MMX counterparts. Based on a patch by Loren Merritt <lorenm AT u washington edu>. Originally committed as revision 24340 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Ronald S. Bultje	1878f685c0	Implement chroma (width=8) inner loopfilter MMX/MMX2/SSE2 functions. Originally committed as revision 24339 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Ronald S. Bultje	fb9bdf048c	Be more efficient with registers or stack memory. Saves 8/16 bytes stack for x86-32, or 2 MM registers on x86-64. Originally committed as revision 24338 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Ronald S. Bultje	3facfc99da	Change function prototypes for width=8 inner and mbedge loopfilter functions so that it does both U and V planes at the same time. This will have speed advantages when using SSE2 (or higher) optimizations, since we can do both the U and V rows together in a single xmm register. This also renames filter16 to filter16y and filter8 to filter8uv so that it's more obvious what each function is used for. Originally committed as revision 24337 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago

Ronald S. Bultje	ede1b9665a	Give x86 r%d registers names, this will simplify implementation of the chroma inner loopfilter, and it also allows us to save one register on x86-64/sse2. Originally committed as revision 24269 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Ronald S. Bultje	526e831a46	Change return statement, the REP_RET is a mistake since the else case (x86-64, sse2) doesn't actually loop, so REP_RET isn't necessary. Originally committed as revision 24268 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
