* Inline asm for VP56 arith coderEli Friedman2010-07-23
| | | | | | | | | This is a lot more reliable to get cmov rather than trying to trick gcc into generating it, useful since it's 2% faster overall. Patch by Eli Friedman <eli.friedman at gmail> Originally committed as revision 24471 to svn://svn.ffmpeg.org/ffmpeg/trunk
* VP8: optimize DC-only chroma case in the same way as luma.Jason Garrett-Glaser2010-07-23
| | | | | | | Add MMX idct_dc_add4uv function for this case. ~40% faster chroma idct. Originally committed as revision 24455 to svn://svn.ffmpeg.org/ffmpeg/trunk
* VP8 asm: cosmetics (spacing)Jason Garrett-Glaser2010-07-23
| | | | Originally committed as revision 24453 to svn://svn.ffmpeg.org/ffmpeg/trunk
* VP8: 30% faster idct_mbJason Garrett-Glaser2010-07-23
| | | | | | | | | | 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
* VP8: clear DCT blocks in iDCT instead of using clear_blocks.Jason Garrett-Glaser2010-07-23
| | | | | | ~0.3% faster overall. Originally committed as revision 24448 to svn://svn.ffmpeg.org/ffmpeg/trunk

| | | | Originally committed as revision 24405 to svn://svn.ffmpeg.org/ffmpeg/trunk
* Various VP8 x86 deblocking speedupsJason Garrett-Glaser2010-07-21
| | | | | | | 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
* Make mmx VP8 WHT fasterJason Garrett-Glaser2010-07-21
| | | | | | | 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
* Add header declarations for mmx/sse constants missing themDavid Conrad2010-07-21
| | | | Originally committed as revision 24381 to svn://svn.ffmpeg.org/ffmpeg/trunk
* Move ff_pw_* from vc1dsp_mmx.c to dsputil_mmx.cDavid Conrad2010-07-21
| | | | | | Should fix compilation with icc and should help prevent any future duplicates Originally committed as revision 24380 to svn://svn.ffmpeg.org/ffmpeg/trunk
* VP8 MBedge loopfilter MMX/MMX2/SSE2 functions for both luma (width=16)Ronald S. Bultje2010-07-20
| | | | | | and chroma (width=8). Originally committed as revision 24378 to svn://svn.ffmpeg.org/ffmpeg/trunk
* Chroma (width=8) inner loopfilter MMX/MMX2/SSE2 for VP8 decoder.Ronald S. Bultje2010-07-20
| | | | Originally committed as revision 24377 to svn://svn.ffmpeg.org/ffmpeg/trunk
* Revert r24339 (it causes fate failures on x86-64) - I'll figure out what'sRonald S. Bultje2010-07-19
| | | | | | wrong with it tomorrow or so, then re-submit. Originally committed as revision 24341 to svn://svn.ffmpeg.org/ffmpeg/trunk
* Remove FF_MM_SSE2/3 flags for CPUs where this is generally not faster thanRonald S. Bultje2010-07-19
| | | | | | | | | | | | | | 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>.

* Implement chroma (width=8) inner loopfilter MMX/MMX2/SSE2 functions.Ronald S. Bultje2010-07-19
| | | | Originally committed as revision 24339 to svn://svn.ffmpeg.org/ffmpeg/trunk
* Be more efficient with registers or stack memory. Saves 8/16 bytes stackRonald S. Bultje2010-07-19
| | | | | | for x86-32, or 2 MM registers on x86-64. Originally committed as revision 24338 to svn://svn.ffmpeg.org/ffmpeg/trunk
* Change function prototypes for width=8 inner and mbedge loopfilter functionsRonald S. Bultje2010-07-19
| | | | | | | | | | | 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

* Give x86 r%d registers names, this will simplify implementation of the chromaRonald S. Bultje2010-07-16
| | | | | | 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
* Change return statement, the REP_RET is a mistake since the else case (x86-64,Ronald S. Bultje2010-07-16
| | | | | | sse2) doesn't actually loop, so REP_RET isn't necessary. Originally committed as revision 24268 to svn://svn.ffmpeg.org/ffmpeg/trunk
