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

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	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	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	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

Frank Barchard	e3a8454205	SWSCALE: Increase maximim with from 5120 to 21504 Heres a benchmark VOFW 5120 VOFW 21504 Note 10438.8 10344.2 timex ffmpeg -y -i tulip2.mp4 tulip2.yuv 25611.9 24256.9 timex ffmpeg -y -itulip2.mp4 -s 1272x724 tulip2.yuv 24485.7 26006.6 28573.1 24291.3 24069.1 26995.9 25684.95 25387.675 average This is on a Nehalem i7. Despite being a 500 frame, 720p video, the numbers fluctuate, so I took an average of 4 runs. Another reason I'd like this change is youtube accepts videos with higher resolutions than 5120. 16384 is vp8's maximum resolution, so that should keep us amused for a little longer.
