Derek Buitenhuis	a4bd4733c0	swscale: Allow the max filter size to be set at compile time This can help "extreme" resizes, e.g with some 4k stuff. Signed-off-by: Derek Buitenhuis <derek.buitenhuis@gmail.com>	11 years ago
James Almer	345f2234d1	x86/scale: fix xmm register count for hscale*_sse2 xmm6 was being clobbered in ff_hscale8to{15,19}_8_sse2 on Win64 Signed-off-by: James Almer <jamrial@gmail.com> Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	11 years ago
Diego Biurrun	880e2aa236	Remove all Blackfin architecture optimizations Blackfin is a painful platform to work with, no test machines are available and the range of multimedia applications is dubious. Thus it only represents a maintenance burden.	11 years ago

Øyvind Kolås	3e6016622e	swscale: add two spatially stable dithering methods Both of these dithering methods are from http://pippin.gimp.org/a_dither/ for GIF they can be considered better than bayer (provides more gray-levels), and spatial stability - often more than twice as good compression and less visual flicker than error diffusion methods (the methods also avoids error-shadow artifacts of diffusion dithers). These methods are similar to blue/green noise type dither masks; but are simple enough to generate their mask on the fly. They are still research work in progress; though more expensive to generate masks (which can be used in a LUT) like 'void and cluster' and similar methods will yield superior results	11 years ago
