Ronald S. Bultje	b7542dd3d7	swscale: fix V plane memory location in bilinear/unscaled RGB/YUYV case. Fixes bug 221. CC: libav-stable@libav.org	13 years ago
Ronald S. Bultje	7e4d9d5d45	win64: add a XMM clobber test configure option. This will be useful to test more aggressively for failures to mark XMM registers as clobbered in Win64 builds, and prevent regressions thereof. Based on a patch by Ramiro Polla <ramiro.polla@gmail.com>	13 years ago
Ronald S. Bultje	de53b9068a	swscale: implement MMX, SSE2 and AVX functions for RGB32 input.	13 years ago
Ronald S. Bultje	378c5ef9ae	swscale: enable dithering in MMX functions. This was accidently disabled. Signed-off-by: Ronald S. Bultje <rsbultje@gmail.com>	13 years ago
Ronald S. Bultje	212f161caa	swscale: make rgb24 function macros slightly smaller.	13 years ago
Ronald S. Bultje	b5d08c27c3	swscale: convert rgb/bgr24ToY/UV_mmx functions from inline asm to yasm. Also implement sse2/ssse3/avx versions.	13 years ago
Ronald S. Bultje	3b15a6d742	config.asm: change %ifdef directives to %if directives. This allows combining multiple conditionals in a single statement.	13 years ago
Ronald S. Bultje	3c172a4106	swscale: change yuv2yuvX code to use cpuflag().	13 years ago
Ronald S. Bultje	b14fa5572c	swscale: fix crash in fast_bilinear code when compiled with -mred-zone. Additional comments from Måns Rullgard have been integrated by Reinhard Tartler. Signed-off-by: Reinhard Tartler <siretart@tauware.de>	13 years ago
Oka Motofumi	cd44521625	swscale: specify register type. Fixes a compilation failure on win64. Signed-off-by: Ronald S. Bultje <rsbultje@gmail.com>	13 years ago
Ronald S. Bultje	2170a0e6ad	swscale: convert yuy2/uyvy/nv12/nv21ToY/UV from inline asm to yasm. Also implement SSE2/AVX variants.	13 years ago
Ronald S. Bultje	6ea64339c5	swscale: split scale.asm. scale.asm keeps horizontal scaling functions, whereas output.asm gets the vertical scaling/output functions.	13 years ago
Diego Biurrun	3c62a71486	swscale_mmx: drop no longer required parameters from VSCALEX macros	13 years ago
Diego Biurrun	52de07e1f1	swscale: Mark yuv2planeX_8_mmx as MMX2; it contains MMX2 instructions.	13 years ago
Mans Rullgard	373211d828	Remove extraneous semicolons These semicolons cause invalid empty top-level declarations. Signed-off-by: Mans Rullgard <mans@mansr.com>	13 years ago
Ronald S. Bultje	8283f90a52	swscale: handle unaligned buffers in yuv2plane1 The issue had been introduced in `c435653627` Signed-off-by: Luca Barbato <lu_zero@gentoo.org>	13 years ago
Ronald S. Bultje	c435653627	swscale: write yuv2plane1 MMX/SSE2/SSE4/AVX functions.	13 years ago
Ronald S. Bultje	9e66b892e8	swscale: add missing colons to x86 assembly yuv2planeX. This fixes assembling using "nasm".	13 years ago
Ronald S. Bultje	6cacecdca3	swscale: make yuv2yuvX_10_sse2/avx 8/9/16-bits aware. Also implement MMX/MMX2 versions and SSE4 versions.	13 years ago
Kieran Kunhya	7fbbf95293	yuv2planeX10 SIMD Signed-off-by: Ronald S. Bultje <rsbultje@gmail.com>	13 years ago
Kieran Kunhya	34e8d147b3	Split out yuv2yuv1 luma and chroma in order to make them generic DSP functions Signed-off-by: Ronald S. Bultje <rsbultje@gmail.com>	13 years ago
Ronald S. Bultje	6aa3cac6bf	swscale: use aligned move for storage into temporary buffer. The intermediate buffer is always aligned.	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
Ronald S. Bultje	3f04ab4fcd	swscale: split hScale() function pointer into h[cy]Scale(). This allows using more specific implementations for chroma/luma, e.g. we can make assumptions on filterSize being constant, thus avoiding that test at runtime.	14 years ago
Ronald S. Bultje	28c1115a91	swscale: use 15-bit intermediates for 9/10-bit scaling.	14 years ago
Ronald S. Bultje	5c391a161a	swscale: rename uv_off/uv_off2 to uv_off_px/byte.	14 years ago
Ronald S. Bultje	4e3e333a79	swscale: error dithering for 16/9/10-bit to 8-bit. Based on a somewhat similar idea in FFmpeg's swscale copy.	14 years ago
Ronald S. Bultje	42d622fab3	swscale: fix 16-bit scaling when output is 8-bits. We would use the second half of the U plane buffer, rather than the V plane buffer, to output the V plane pixels.	14 years ago
Ronald S. Bultje	8a8d0ce208	swscale: for >8bit scaling, read in native bit-depth. For 9/10bit, it means we don't have to upscale to 16bit before actual scaling or pixel format conversion, and thus a performance gain.	14 years ago
Ronald S. Bultje	ef1ee362b3	swscale: implement >8bit scaling support. This means that precision is retained when scaling between sample formats with >8 bits per component (48bit RGB, 16bit grayscale, 9/10/16bit YUV).	14 years ago
Ronald S. Bultje	13a099799e	swscale: change prototypes of scaled YUV output functions. Remove unused variables "flags" and "dstFormat" in yuv2packed1, merge source rows per plane for yuv2packed[12], and make every source argument int16_t (some where invalidly set to uint16_t). This prevents stack pollution and is part of the Great Evil Plan to simplify swscale.	14 years ago
Ronald S. Bultje	0d994b2f45	swscale: don't use planar output functions to write to NV12/21. This prevents a crash when converting to NV12/21 without the bitexact flags enabled.	14 years ago
Ronald S. Bultje	97535ffb97	swscale: remove unused xInc/srcW arguments from hScale().	14 years ago
Diego Biurrun	a60466dbc3	swscale: Remove HAVE_MMX from files that are only compiled with MMX enabled.	14 years ago
Diego Biurrun	97e057ff81	swscale: Fix compilation with --disable-mmx2. Some MMX2 functions were being referenced without proper #ifdefs.	14 years ago
Ronald S. Bultje	a27db4c349	swscale: fix function declaration keywords in x86/swscale_template.c. Remove inline keyword for functions that are only called through their function pointers (and thus cannot be inlined); add av_cold keyword to init function, and use av_always_inline instead of inline for functions that must be inlined for performance reasons.	14 years ago
Ronald S. Bultje	9bcbb250e2	swscale: fix types of assembly arguments. This prevents the following compiler warnings: "warning: initialization from incompatible pointer type". Since the variables are only ever used in inline assembly, their type is actually irrelevant (so the part where it was wrong did not invoke any buggy behaviour).	14 years ago
Ronald S. Bultje	496d95c34c	swscale: move two macros that are only used once into caller. This way, they look like regular code, which is easier to understand.	14 years ago
Ronald S. Bultje	0fb5193156	swscale: reindent x86 init code.	14 years ago
Ronald S. Bultje	ca364a5b43	swscale: extract SWS_FULL_CHR_H_INT conditional into init code.	14 years ago
Ronald S. Bultje	bda9b20fa4	swscale: un-special-case yuv2yuvX16_c(). Make yuv2yuvX16_c a function pointer for yuv2yuvX(), so that the function pointer becomes bitdepth-independent.	14 years ago
Ronald S. Bultje	983260b0a4	swscale: split out x86/swscale_template.c from swscale.c.	14 years ago
Anton Khirnov	b8e893399f	sws: replace all long with int. Signed-off-by: Ronald S. Bultje <rsbultje@gmail.com>	14 years ago
Ronald S. Bultje	009f829dde	swscale: fix crash in bilinear scaling.	14 years ago
Diego Biurrun	5a5a0f1613	swscale: Remove unused variables in x86 code. libswscale/x86/swscale_template.c:2072: warning: unused variable ‘canMMX2BeUsed’ libswscale/x86/swscale_template.c:2145: warning: unused variable ‘canMMX2BeUsed’ libswscale/x86/swscale_template.c:2209: warning: unused variable ‘chrVPixBuf’ libswscale/x86/swscale_template.c:2237: warning: unused variable ‘chrVSrcPtr’	14 years ago
Ronald S. Bultje	f327bfa6dc	swscale: fix build with --disable-swscale-alpha.	14 years ago
Ronald S. Bultje	9f5d45025e	swscale: fix non-bitexact yuv2yuv[X2]() MMX/MMX2 functions.	14 years ago
Ronald S. Bultje	e758573a88	swscale: fix compile on x86-32.	14 years ago
Ronald S. Bultje	b4a224c5e4	swscale: split chroma buffers into separate U/V planes. Preparatory step to implement support for sizes > VOFW.	14 years ago
Ronald S. Bultje	522d65ba25	rgb2rgb: remove duplicate mmx/mmx2/3dnow/sse2 functions. Many functions have such a prefix, but do not actually use any instructions or features from that set, thus giving the false impression that swscale is highly optimized for a particular system, whereas in reality it is not.	14 years ago
