Michael Niedermayer	920dd84bf1	sws/x86: remove 8bit rgb2yuv coefficient case for rgb24toyv12 special converter This simplifies the code and improves quality at the expense of a slight slowdown of a rarely used function (no fate test uses it).

Diego Biurrun	b6649ab503	cosmetics: Remove unnecessary extern keywords from function declarations	12 years ago
Michael Niedermayer	5e947aeb59	sws/x86: improve rounding for yuv2yuvX This tries to compensate for the errors introduced by the rounding of pmulhw Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	12 years ago

Clément Bœsch	178ecfc257	swscale: fix To{Y,UV} extern prototypes. This fix a bunch of "assignment from incompatible pointer type" warnings with GCC.	12 years ago
Michael Niedermayer	ef912134f0	x86/swscale: use unsigned to build SIMD values to avoid signed overflow Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	12 years ago
Diego Biurrun	e0c6cce447	x86: Replace checks for CPU extensions and flags by convenience macros This separates code relying on inline from that relying on external assembly and fixes instances where the coalesced check was incorrect.	12 years ago
Carl Eugen Hoyos	a26789cf9f	Fix compilation with yasm-0.6.2.	13 years ago
Diego Biurrun	17337f54c0	x86: Split inline and external assembly #ifdefs	13 years ago

Mans Rullgard	c318626ce2	x86: rename libavutil/x86_cpu.h to libavutil/x86/asm.h This puts x86-specific things in the x86/ subdirectory where they belong. Signed-off-by: Mans Rullgard <mans@mansr.com>	13 years ago
Diego Biurrun	239fdf1b4a	x86: build: replace mmx2 by mmxext Refactoring mmx2/mmxext YASM code with cpuflags will force renames. So switching to a consistent naming scheme beforehand is sensible. The name "mmxext" is more official and widespread and also the name of the CPU flag, as reported e.g. by the Linux kernel.	13 years ago
Diego Biurrun	5a6e3c039c	swscale: Mark all init functions as av_cold	13 years ago
Diego Biurrun	16d2a1a51c	swscale: x86: Drop pointless _mmx suffix from filenames The files do not contain only MMX code.	13 years ago
Ronald S. Bultje	b2668c85e9	x86: swscale: Place inline assembly code under appropriate #ifdefs Fixes compilation for compilers that do not support gcc inline assembly. Signed-off-by: Diego Biurrun <diego@biurrun.de>	13 years ago

Ronald S. Bultje	1d8c4af396	swscale: take first/lastline over/underflows into account for MMX. Fixes crashes for extremely large resizes (several 100-fold). Found-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind CC: libav-stable@libav.org	13 years ago
Ronald S. Bultje	b18f8cbf3d	Revert two swscale commits. Revert "swscale: update context offsets after removal of AlpMmxFilter." (commit `a95e3fa90b`) and Revert "swscale: Remove some write-only variables related to alpha handling." (commit `9d03cb9fc5`). They broke alpha handling - it's the evil inline asm that still uses that variable, so it's not truely write-only.	13 years ago
Michael Niedermayer	e7dbfa59f2	swscale: enable some more SIMD functions. They no longer just segfault. Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	13 years ago

Ronald S. Bultje	e0c3e07387	sws: implement MMX/SSE2/SSSE3/SSE4 versions for horizontal scaling. Speed: from 3.9x to 9.6x speed improvement over C, and some small (up to 15%) speed improvements over existing MMX code (particularly for bigger filters).	13 years ago
