rcombs	3e00b9e395	swscale/x86/init: use isSemiPlanarYUV Fixes P210/P410 cases introduced (and broken) in `88d804b7ff`	3 years ago
Alan Kelly	eebe406c80	libswscale: Test AV_CPU_FLAG_SLOW_GATHER for hscale functions. This is instead of EXTERNAL_AVX2_FAST so that the avx2 hscale functions are only used where they are faster.	3 years ago
Alan Kelly	86663963e6	x86/swscale: fix minor coding style issues Signed-off-by: James Almer <jamrial@gmail.com>	3 years ago
Alan Kelly	f900a19fa9	libswscale: Adds ff_hscale8to15_4_avx2 and ff_hscale8to15_X4_avx2 for all filter sizes. Fixes so that fate under 64 bit Windows passes. These functions replace all ff_hscale8to15_*_ssse3 when avx2 is available. Signed-off-by: James Almer <jamrial@gmail.com>	3 years ago
Alan Kelly	dc57762cb4	libswscale/x86/swscale: Only call ff_yuv2yuvX functions if the input size is > 0 Signed-off-by: Michael Niedermayer <michael@niedermayer.cc>	4 years ago
Andreas Rheinhardt	c23a5523b5	swscale/x86/swscale: Remove unused ASM constants The last user of g15Mask, r15Mask, g16Mask and r16Mask was disabled in `77a416e8aa` and finally removed in 36e8de07ed62609df45d064b56501e3084d25723; b15Mask and b16Mask were apparently always unused (except for in_asm_used_var_warning_killer, a function that only existed to make the compiler not optimize ASM constants away). w10 is unused since `d604bab901`, w02 since `ef423a6618`.

James Almer	c00567647e	swscale/x86/swscale: fix mix of inline and external function definitions This includes removing pointless static function forward declarations. Signed-off-by: James Almer <jamrial@gmail.com>	4 years ago
James Almer	c2bf1dcace	swscale/x86/swscale: fix compilation with old yasm Where AVX2 may not be supported. Signed-off-by: James Almer <jamrial@gmail.com>	4 years ago
Alan Kelly	554c2bc708	swscale: move yuv2yuvX_sse3 to yasm, unrolls main loop And other small optimizations for ~20% speedup.	4 years ago
Anton Khirnov	e15371061d	lavu/mem: move the DECLARE_ALIGNED macro family to mem_internal on next+1 bump They are not properly namespaced and not intended for public use.	4 years ago
Nelson Gomez	bc01337db4	swscale/x86/output: add AVX2 version of yuv2nv12cX 256 bits is just wide enough to fit all the operands needed to vectorize the software implementation, but AVX2 is needed to for a couple of instructions like cross-lane permutation. Output is bit-for-bit identical to C. Signed-off-by: Nelson Gomez <nelson.gomez@microsoft.com>	4 years ago
Ruiling Song	4700f7d6fc	swscale/swscale: remove useless code Signed-off-by: Ruiling Song <ruiling.song@intel.com> Signed-off-by: Michael Niedermayer <michael@niedermayer.cc>	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. NASM code almost has no impact on the perfromance. Signed-off-by: Ting Fu <ting.fu@intel.com> Signed-off-by: Michael Niedermayer <michael@niedermayer.cc>	5 years ago
Andreas Rheinhardt	736c7c20e7	swscale/x86/swscale: Fix undefined left shifts of negative numbers This affected many FATE-tests: The number of failing tests went down from 663 to 344. (Both numbers exclude tests that failed because of unaligned accesses in code that is inside #if HAVE_FAST_UNALIGNED.) Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@gmail.com> Signed-off-by: Michael Niedermayer <michael@niedermayer.cc>	5 years ago
Thomas Köppe	43171a2a73	Fix missing used attribute for inline assembly variables Variables used in inline assembly need to be marked with attribute((used)). Static constants already were, via the define of DECLARE_ASM_CONST. But DECLARE_ALIGNED does not add this attribute, and some of the variables defined with it are const only used in inline assembly, and therefore appeared dead. This change adds a macro DECLARE_ASM_ALIGNED that marks variables as used. This change makes FFMPEG work with Clang's ThinLTO. Signed-off-by: Michael Niedermayer <michael@niedermayer.cc>	7 years ago

Vitor Sessak	55d11d277b	swscale/x86: do not expect registers to be preserved across inline ASM blocks Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	10 years ago
Vittorio Giovara	e96c3b81ca	avutil: rename AV_PIX_FMT_Y400A to AV_PIX_FMT_YA8 The rationale is that you have a packed format in form <greyscale sample> <alpha sample> <greyscale sample> <alpha sample> and shortening greyscale to 'G' might make one thing about Greenscale instead. An alias pixel format and color space name are provided for compatibility.	10 years ago
Carl Eugen Hoyos	891307b4d1	s86/scale: Do not return the result of a (void) function from a void function. Fixes compilation with Sun C 5.12. Reported by Bradley Mitchell in ticket #3649.	11 years ago

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).
