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
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
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	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	f28aaae1c5	swscale: amend documentation to mention use of native depth for scaling. Signed-off-by: Diego Biurrun <diego@biurrun.de>	14 years ago
Mans Rullgard	abc78a5a7c	Do not include log.h in avutil.h Signed-off-by: Mans Rullgard <mans@mansr.com>	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
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	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
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	97535ffb97	swscale: remove unused xInc/srcW arguments from hScale().	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	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	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	6af2801088	swscale: split swscale.c in unscaled and generic conversion routines. This duplicates the function fillPlane().	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	0e5d31b16b	swscale: split out unscaled altivec YUV converters in their own file.	14 years ago

Ronald S. Bultje	009f829dde	swscale: fix crash in bilinear scaling.	14 years ago
Ronald S. Bultje	93681fbd50	swscale: fix compile on ppc.	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	e66149e714	swscale: force --enable-runtime-cpudetect and remove SWS_CPU_CAPS_*.	14 years ago
Ronald S. Bultje	c8f487deae	swscale: fix YUV420P 9/10bit support. Fix handling of input if not in native endianness, and add support for 9/10-bit output. This allows us to force endianness of YUV420P 9/10bit in the H264/10bit fate tests, which should fix them on big-endian systems.	14 years ago
Oskar Arvidsson	42239ced65	Add pixel formats for 9- and 10-bit yuv420p. Also add support for these formats in libswscale. Needed for high bit depth h264 decoding. Signed-off-by: Ronald S. Bultje <rsbultje@gmail.com>	14 years ago
Peter Ross	1afbae100b	libswcale: PIX_FMT_BGR48LE and PIX_FMT_BGR48BE scaler implementation Signed-off-by: Anton Khirnov <anton@khirnov.net>	14 years ago
Luca Barbato	0e1a5434e2	swscale: Factorize FAST_BGR2YV12 definition. It is used only for x86 so it will eventually be moved with that code into the x86 arch subdirectory.	14 years ago
Mans Rullgard	2912e87a6c	Replace FFmpeg with Libav in licence headers Signed-off-by: Mans Rullgard <mans@mansr.com>	14 years ago

Ramiro Polla	c3ab0004ae	Revert r31153.

Ramiro Polla	d9d14dc607	Use int instead of long to pass width parameters in non-public functions. long was being incorrectly used as an x86-sized register, both for 32 and 64 bits, but this is not the case in win64.
