Ramiro Polla	8744764a4c	swscale/x86/yuv2rgb: add ssse3 yuv42{0,2}p -> gbrp unscaled colorspace converters Note: this implementation is limited to x86_64 due to general purpose register pressure. checkasm --bench on an Intel(R) Core(TM) i5-5300U CPU @ 2.30GHz: yuv420p_gbrp_8_c: 118.5 yuv420p_gbrp_8_ssse3: 93.3 yuv420p_gbrp_128_c: 1068.3 yuv420p_gbrp_128_ssse3: 319.3 yuv420p_gbrp_1080_c: 8841.8 yuv420p_gbrp_1080_ssse3: 2211.8 yuv420p_gbrp_1920_c: 15903.8 yuv420p_gbrp_1920_ssse3: 3814.3 yuv422p_gbrp_8_c: 144.8 yuv422p_gbrp_8_ssse3: 93.8 yuv422p_gbrp_128_c: 1395.8 yuv422p_gbrp_128_ssse3: 313.0 yuv422p_gbrp_1080_c: 11551.5 yuv422p_gbrp_1080_ssse3: 2240.8 yuv422p_gbrp_1920_c: 20585.3 yuv422p_gbrp_1920_ssse3: 5249.5 yuva420p_gbrp_8_c: 117.5 yuva420p_gbrp_8_ssse3: 92.0 yuva420p_gbrp_128_c: 1593.0 yuva420p_gbrp_128_ssse3: 319.3 yuva420p_gbrp_1080_c: 8694.5 yuva420p_gbrp_1080_ssse3: 2186.0 yuva420p_gbrp_1920_c: 15946.5 yuva420p_gbrp_1920_ssse3: 3805.3	4 months ago
Ramiro Polla	ac6263945a	swscale/x86/yuv2rgb: Detemplatize Every function in yuv2rgb_template.c is only compiled exactly once, so detemplatize it.	6 months ago
Ramiro Polla	4f7f9b1026	swscale: remove unconditional #define DITHER1XBPP This seems to have had an use in the past, but it is now defined unconditionally.	6 months ago
Ramiro Polla	61e851381f	swscale/yuv2rgb/x86: remove mmx/mmxext yuv2rgb functions These functions are either slower or barely faster than the C LUT yuv2rgb code.	6 months ago
Andreas Rheinhardt	2831837182	swscale/x86/yuv2rgb: Remove obsolete MMX functions x64 always has MMX, MMXEXT, SSE and SSE2 and this means that some functions for MMX, MMXEXT and 3dnow are always overridden by other functions (unless one e.g. explicitly disables SSE2) for x64. So given that the only systems that benefit from these functions are truely ancient 32bit x86s they are removed. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>	3 years ago
Andreas Rheinhardt	49db6e4b4e	swscale/x86/yuv2rgb: Remove unused ASM constants mmx_grnmask is unused since `531f97b0c3`, the other constants since `e934194b6a`. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@gmail.com>	4 years ago

Ting Fu	fc6a5883d6	libswscale/x86/yuv2rgb: add ssse3 version Tested using this command: /ffmpeg -pix_fmt yuv420p -s 19201080 -i ArashRawYuv420.yuv \ -vcodec rawvideo -s 19201080 -pix_fmt rgb24 -f null /dev/null The fps increase from 389 to 640 on Intel(R) Core(TM) i7-8700K CPU @ 3.70GHz Signed-off-by: Ting Fu <ting.fu@intel.com>	5 years ago
Ting Fu	e934194b6a	libswscale/x86/yuv2rgb: Change inline assembly into nasm code The original inline assembly and nasm code have the same fps when called by command.

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
