Anton Mitrofanov	142e76f105	swscale: fix crash with dithering due incorrect offset calculation. ptrdiff_t can be 4 bytes, which leads to the next element being 4-byte aligned and thus at a different offset than intended. Forcing 8-byte alignment forces equal offset of dither16/32 on x86-32 and x86-64. Signed-off-by: Ronald S. Bultje <rsbultje@gmail.com>	14 years ago
Ronald S. Bultje	5c391a161a	swscale: rename uv_off/uv_off2 to uv_off_px/byte.	14 years ago
Ronald S. Bultje	1ce724ee39	swscale: implement error dithering in planarCopyWrapper. Based on a somewhat similar idea in FFmpeg's swscale.	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	7d7bacf0f1	swscale: fix overflow in 16-bit vertical scaling. We operated on 31-bits, but with e.g. lanczos scaling, values can add up to beyond 0x80000000, thus leading to output of zeroes. Drop one bit of precision fixes this.	14 years ago
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
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	f28aaae1c5	swscale: amend documentation to mention use of native depth for scaling. Signed-off-by: Diego Biurrun <diego@biurrun.de>	14 years ago
Diego Biurrun	e589e4b82d	Remove unused static tables and static inline functions.	14 years ago

Mans Rullgard	d49ea4afb4	Do not include pixfmt.h in avutil.h Signed-off-by: Mans Rullgard <mans@mansr.com>	14 years ago
Diego Biurrun	01c17c88ed	doxygen: Remove spurious documentation for non-existing function parameters.	14 years ago
Ronald S. Bultje	8f440223f6	swscale: disable full_chroma_int when converting to non-24/32bpp RGB. This functionality is only implemented for RGB24/32 and causes crashes otherwise.	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	4578435f35	swscale: Add Doxygen for hyscale_fast/hScale.	14 years ago

Ronald S. Bultje	d6cc6ac6b8	swscale: Add Doxygen for yuv2planar/yuv2packed functions.	14 years ago
Mans Rullgard	57b4a3dd2b	build: include sub-makefiles using full path instead of symlinks Signed-off-by: Mans Rullgard <mans@mansr.com>	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	dc179ec819	swscale: split yuv2packedX_altivec in smaller functions. This will likely lead to a considerable performance boost, since it removes a branch from the inner loop. 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	a6213f3dce	build: Remove redundant config.mak includes from subdirectory Makefiles. Calling Make from subdirectories is not supported and config.mak has multiple inclusion guards anyway, so the top-level include is enough.	14 years ago
Diego Biurrun	087d93f568	swscale: Remove unused variable from ff_bfin_get_unscaled_swscale().	14 years ago
Reinhard Tartler	0793531859	Bump major version for `b8e893399f` On architectures such as x86 (both 32 bit and 64bit), the stack element size is fixed, which maintains alignment. Here, this change does not break anything. However, we also support also other architectures where this property is not maintained and therefore, applications will crash horribly. This change effectively forces all applications to be recompiled against libswscale.	14 years ago
Janne Grunau	3636e791ec	swscale: use SwsContext for av_log when available Signed-off-by: Diego Biurrun <diego@biurrun.de>	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	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
