Michael Niedermayer	cca81e7eb0	sws: gbr24p input support Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	13 years ago
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
Jean First	9569a3c9f4	Add new pix_fmt RGBA64	13 years ago
Michael Niedermayer	d06c5b44cc	swscale: drop redundant code. Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	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
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	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	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	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	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
Michael Niedermayer	7a8228c05e	sws: make dither_scale const Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	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	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
Stefano Sabatini	b932eb1be6	swscale: reintroduce sws_format_name() symbol Reintroduce the internal symbol which was removed in: commit `e1197b9e17` Author: Stefano Sabatini <stefano.sabatini-lala@poste.it> Date: Sun May 29 17:57:40 2011 +0200 swscale: remove sws_format_name() Use av_get_pix_fmt_name() instead. The symbol is used by some external libs (hi libx264!), this gives time to them to use the recently added av_get_pix_fmt_name() rather than an internal symbol.	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
ami_stuff	1d14edb724	Use VOFW 21503 as a default value for all types of the CPUs	14 years ago
