Michael Niedermayer	bd141af460	swscale: Fix prototypes of *toyv12 so they can be used with planar rgb input. Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	13 years ago
Kieran Kunhya	4d4d0e8176	Fix unnecessary shift with 9/10bit vertical scaling Signed-off-by: Diego Biurrun <diego@biurrun.de>	13 years ago
Michael Niedermayer	d06c5b44cc	swscale: drop redundant code. Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	13 years ago
Clément Bœsch	7c14c24250	sws: fix a huge amount of incompatible pointer type arguments warnings.	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.	13 years ago
Michael Niedermayer	d9c9a0c767	sws: remove hScale16NX_c() Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	13 years ago
Michael Niedermayer	66bb5cd592	sws: remove hScale16N() and use ronalds reformated version of it. Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	13 years ago
Michael Niedermayer	3652409f5b	sws: remove unneeded code from last merge Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	13 years ago
Ronald S. Bultje	28c1115a91	swscale: use 15-bit intermediates for 9/10-bit scaling.	13 years ago
Ronald S. Bultje	62ee0e6a97	Revert "swscale: use 15-bit intermediates for 9/10-bit scaling." This reverts commit `ac0fb59348`. It causes valgrind errors which I'll want to investigate before resubmitting this.	13 years ago
Ronald S. Bultje	ac0fb59348	swscale: use 15-bit intermediates for 9/10-bit scaling.	13 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
Michael Niedermayer	08b57574c6	sws: fix non native endian 9-15 bit input with 16bit out	14 years ago
Michael Niedermayer	ca78fa24b7	sws: disable scale16 when int32 is used	14 years ago
Michael Niedermayer	987e4c1787	sws: fix rgb -> 16bit	14 years ago
Michael Niedermayer	d2c910b9a4	sws: fix gray16_1	14 years ago
Michael Niedermayer	9470205414	sws:ix yuv2rgb48_1_c_template()	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
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	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	afb9d4e8f1	swscale: fix another yuv range conversion overflow in 16bit scaling. (cherry picked from commit `81cc7d0bd1`)	14 years ago
Ronald S. Bultje	ebb0d60353	swscale: fix yuv range correction when using 16-bit scaling. (cherry picked from commit `e0b8fff6c7`)	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	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
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
Michael Niedermayer	15b4f6449d	swscale: fix mono input for width%8 Fixes ticket193 Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	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
