Michael Niedermayer	29fb1b5a06	sws: Fix chroma init for 32bit buffers. Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	14 years ago
Ronald S. Bultje	c59f9a68e2	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	93a10dd561	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	71a04bc19d	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. (cherry picked from commit `bf2cba4532`)	14 years ago
Ronald S. Bultje	ac9ac45aca	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
Michael Niedermayer	08b57574c6	sws: fix non native endian 9-15 bit input with 16bit out	14 years ago

Michael Niedermayer	ae05dd8731	sws: fix 16/32 bug from merge	14 years ago
Ronald S. Bultje	948ccdadf4	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
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	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	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

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	45f6ffe5e9	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

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
Reimar Döffinger	1109680434	Revert "build: Remove redundant config.mak includes from subdirectory Makefiles." This reverts commit `a6213f3dce`.	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
