Ronald S. Bultje	bf2cba4532	swscale: fix crash in 8-bpc bilinear output without alpha. We accessed the alpha array even it wasn't used and didn't exist, hence leading to a NULL pointer segfault.	14 years ago
Ronald S. Bultje	f44d50a94c	swscale: fix 16-bit horizontal scaling underflow. When using e.g. lanczos scaling, values can drop below 0, so they should never be unsigned.	14 years ago
Diego Biurrun	e589e4b82d	Remove unused static tables and static inline functions.	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	81cc7d0bd1	swscale: fix another yuv range conversion overflow in 16bit scaling.	14 years ago
Mohamed Naufal	705b21a06e	swscale: Unbreak build with --enable-small This fixes building with --enable-small, by using the correct variable name. Signed-off-by: Martin Storsjö <martin@martin.st>	14 years ago
Ronald S. Bultje	e0b8fff6c7	swscale: fix yuv range correction when using 16-bit scaling.	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	dff5a83532	swscale: re-add support for non-native endianness. This works through some non-obvious hacks in utils.c.	14 years ago
Ronald S. Bultje	3d3c814937	swscale: disentangle yuv2rgbX_c_full() into small functions. This is part of the Great Evil Plan to simplify swscale.	14 years ago
Ronald Bultje	6fba14eecb	swscale: split yuv2packed[12X]_c() remainders into small functions. This is part of the Great Evil Plan to simplify swscale.	14 years ago
Ronald S. Bultje	97535ffb97	swscale: remove unused xInc/srcW arguments from hScale().	14 years ago
Ronald S. Bultje	4e05830205	swscale: remove misplaced comment. The comment should have been placed only in yuv2rgb48_X_c_template, not yuv2rgb48_1_c_template.	14 years ago
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	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	df91d09174	swscale: integrate yuv2nv12X_C into yuv2yuvX() function pointers.	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	1674bd2abe	swscale: integrate (literally) swscale_template.c in swscale.c.	14 years ago
Ronald S. Bultje	983260b0a4	swscale: split out x86/swscale_template.c from swscale.c.	14 years ago
Ronald S. Bultje	67d80a5421	swscale: split out ppc _template.c files from main swscale.c.	14 years ago
Ronald S. Bultje	a3e9bb5dee	swscale: remove indirections in ppc/swscale_template.c.	14 years ago
Ronald S. Bultje	0e5d31b16b	swscale: split out unscaled altivec YUV converters in their own file.	14 years ago
Ronald S. Bultje	0d793db1b0	swscale: remove unused COMPILE_TEMPLATE_ALTIVEC.	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	b4a224c5e4	swscale: split chroma buffers into separate U/V planes. Preparatory step to implement support for sizes > VOFW.	14 years ago
Ronald S. Bultje	aaca69c130	swscale: remove swScale_{c,MMX,MMX2} duplication.	14 years ago
Ronald S. Bultje	1dd4f4be5a	swscale: remove AMD3DNOW "optimizations". The functions are identical to their MMX counterparts. Thus, pretending that swscale is highly optimized for AMD3DNOW extensions is a poorly executed practical joke at best.	14 years ago
Ronald S. Bultje	fe43d5d71e	swscale: remove duplicate code in ppc/ subdirectory.	14 years ago
Ronald S. Bultje	e66149e714	swscale: force --enable-runtime-cpudetect and remove SWS_CPU_CAPS_*.	14 years ago
Kieran Kunhya	6465c820da	Fix 9/10 bit in swscale. Signed-off-by: Ronald S. Bultje <rsbultje@gmail.com>	14 years ago
Ronald S. Bultje	9f54e461fe	swscale: properly inline bits/endianness in yuv2yuvX16inC().	14 years ago
