Ronald S. Bultje	9f63211175	swscale: split out RGB48 output functions from yuv2packed[12X]_c(). This is part of the Great Evil Plan to simplify swscale. Note that you'll see some code duplication between the output functions for different RGB variants, and even between packed-YUV and RGB variants. This is intentional because it improves readability.	14 years ago
Michael Niedermayer	0af8a71d66	swscale: fix JPEG-range YUV scaling artifacts. YUV planes were marked as uint16_t, but they contained signed data. Fixes issue 1108 and 675. Signed-off-by: Ronald S. Bultje <rsbultje@gmail.com>	14 years ago
Ronald S. Bultje	103278f7b0	libavutil/swscale: YUV444P10/YUV444P9 support. Also add missing glue code for recently added YUV422P10 formats to swscale. Signed-off-by: Ronald S. Bultje <rsbultje@gmail.com>	14 years ago
Ronald S. Bultje	af2faf2076	swscale: split YUYV output out of yuv2packed[12X]_c(). This is part of the Great Evil Plan to simplify swscale.	14 years ago
Ronald S. Bultje	6b105e3ee6	swscale: extract monowhite/black output from yuv2packed[12X]_c(). This is part of the Great Evil Plan to simplify swscale.	14 years ago
Ronald S. Bultje	6d4d483eee	swscale: de-macro'ify RGB15/16/32 input functions. Inline functions are easier to read, maintain, modify and test, which justifies the slightly increased source size. This patch also adds support for non-native endianness RGB15/16 and fixes isSupportedOutput() to no longer claim that we support writing non-native RGB565/555/444.	14 years ago
Ronald S. Bultje	e2babb9b47	swscale: rearrange code. This way the code in the file is less cluttered all-over-the- place.	14 years ago
Ronald S. Bultje	dbd3183935	swscale: change 48bit RGB input macros to inline functions. Inline functions are slightly larger in source code, but are easier to handle in source code editors. The binary code generated is the same.	14 years ago
Ronald S. Bultje	f30ee65700	swscale: change 9/10bit YUV input macros to inline functions. Inline functions are slightly larger in source code, but are easier to handle in source code editors. The binary code generated is the same.	14 years ago
Ronald S. Bultje	aa39f5f6d6	swscale: extract gray16 output functions from yuv2packed[12X](). This is part of the Great Evil Plan to simplify swscale.	14 years ago
Ronald S. Bultje	f1e0b90c64	swscale: use standard clipping functions. This generates better code on some non-x86 architectures.	14 years ago
Ronald S. Bultje	e458b53605	swscale: merge macros that are used only once. This reduces source code size without affecting the binary.	14 years ago
Ronald S. Bultje	6e5a8d3c9a	swscale: fix function declarations in swscale.c. Remove inline keyword from functions that are never inlined. Use av_always_inline for functions that should be force-inlined for performance reasons. Use av_cold for init functions.	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	9d84dfce93	swscale: remove unused function. Use of this wrapper was removed in a previous patch, but I forgot to actually remove the function itself.	14 years ago
Ronald S. Bultje	edeb56fa31	swscale: remove duplicate conversion routine in swScale().	14 years ago
Ronald S. Bultje	b73fe70025	swscale: add yuv2planar/packed function typedefs.	14 years ago
Ronald S. Bultje	df91d09174	swscale: integrate yuv2nv12X_C into yuv2yuvX() function pointers.	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	b3b28b080f	swscale: cosmetics.	14 years ago
Ronald S. Bultje	ea28175312	swscale: remove alp/chr/lumSrcOffset. They are hacks added to reuse the same scaling function for different formats and they may cause problems when SIMD implementation of the same functions are used along with pure C functions.	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	6af2801088	swscale: split swscale.c in unscaled and generic conversion routines. This duplicates the function fillPlane().	14 years ago
Ronald S. Bultje	2762ee3034	swscale: cosmetics. Remove duplicate "inC" and "_c" functions that do the same thing; give each function that handles data and acts as a function pointer a "_c" suffix; remove "_c" suffix from functions that are inherently not optimizable. Remove inline keyword from functions that are only used through function pointers.	14 years ago

Ronald S. Bultje	0d793db1b0	swscale: remove unused COMPILE_TEMPLATE_ALTIVEC.	14 years ago
Ronald S. Bultje	808d8ff6bb	swscale: allocate larger buffer to handle altivec overreads. Altivec sws code intentionally overreads buffers for better performance, so we need to allocate larger buffers to handle that.	14 years ago

Diego Biurrun	06b5facd4b	swscale: Remove disabled code.	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	389e2000eb	swscale: delay allocation of formatConvBuffer(). That means it won't be allocated when not needed. Alongside this, it fixes valgrind/fate-detected memory leaks.	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	48520772d9	swscale: use av_clip_uint8() in yuv2yuv1_c().	14 years ago
Ronald S. Bultje	0f4eb8b043	swscale: remove VOF/VOFW.	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	69645c021a	swscale: replace formatConvBuffer[VOF] by allocated array. This allows to convert between formats of arbitrary width, regardless of the value of VOF/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
