Ronald S. Bultje	c0b87359b2	swscale: handle gray16 as a "planar" YUV format (Y-only, of course). This allows removing any gray16-specific code, which is essentially identical to the per-plane code in yuv2plane*().	13 years ago
Ronald S. Bultje	9d9c846491	swscale: use yuv2packed1() functions for unscaled chroma also.	13 years ago
Ronald S. Bultje	d63b7d8c37	swscale: fix incorrect chroma bias in yuv2rgb48_1_c().	13 years ago
Ronald S. Bultje	1ca7dc60d2	swscale: fix invalid memory accesses in yuvpacked1() functions.	13 years ago
Ronald S. Bultje	3e23badd83	swscale: convert yuv2yuvX() to using named arguments.	13 years ago
Ronald S. Bultje	8c433d8a03	swscale: rename "dstw" to "w" to prevent name collisions. "dstw" can collide with the word-version of the "dst" argument, causing all kind of weird stuff down the pipe.	13 years ago
Ronald S. Bultje	ef66a0ed2e	swscale: use named registers in yuv2yuv1_plane() place. Most of the function had been converted before, but I forgot this particular location.	13 years ago
Ronald S. Bultje	dae2ce361a	swscale: enforce a minimum filtersize. At very small dimensions, this calculation could lead to zero-sized filters, which leads to uninitialized output, zero-sized allocations, loop overflows in SIMD that uses do{..}while(i++<filtersize); instead of for(i=0;i<filtersize;i++){..} and several other similar failures. Therefore, require a minimum filtersize of 1. Found-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind CC: libav-stable@libav.org	13 years ago
Diego Biurrun	a2e40cd3e2	swscale: ppc: Add missing header #includes to pass 'make checkheaders'.	13 years ago
Anton Khirnov	38d5533228	pixdesc: mark pseudopaletted formats with a special flag. This makes it possible to dintinguish them from PAL8. Fixes an invalid write in avpicture_layout().	13 years ago
Ronald S. Bultje	783487ae44	swscale: sign-extend integer function argument to qword on x86-64.	13 years ago
Diego Biurrun	0144fe6995	Remove Sun medialib glue code. It is obscure, most likely unused and not bit-exact compared to libavcodec due to a different IDCT transform algorithm.	13 years ago
Ronald S. Bultje	ef1c785f11	swscale: make yuv2yuv1 use named registers.	13 years ago
Ronald S. Bultje	b7542dd3d7	swscale: fix V plane memory location in bilinear/unscaled RGB/YUYV case. Fixes bug 221. CC: libav-stable@libav.org	13 years ago

Ronald S. Bultje	7e4d9d5d45	win64: add a XMM clobber test configure option. This will be useful to test more aggressively for failures to mark XMM registers as clobbered in Win64 builds, and prevent regressions thereof. Based on a patch by Ramiro Polla <ramiro.polla@gmail.com>	13 years ago
Diego Biurrun	148bc235b0	swscale: K&R formatting cosmetics for Blackfin code Also prettyprint some comments in Assembly code.	13 years ago

Ronald S. Bultje	3b15a6d742	config.asm: change %ifdef directives to %if directives. This allows combining multiple conditionals in a single statement.	13 years ago

Paul B Mahol	0cc1a86dc3	rgb2rgb: rgb12to15() Signed-off-by: Ronald S. Bultje <rsbultje@gmail.com>	13 years ago
Ronald S. Bultje	06b0246da0	swscale-test: fix stack overread. Fixes problems in swscale-test where it gives a 3-member array to a function expecting a 4-member array.	13 years ago
Ronald S. Bultje	e7843db3df	swscale: fix invalid conversions and memory problems. Fixes problems where rgbToRgbWrapper() is called even though it doesn't support this particular conversion (e.g. converting from RGB444 to anything). Thirdly, fixes issues where rgbToRgbWrapper() is called for non-native endiannness conversions (e.g. RGB555BE on a LE system). Fourthly, fixes crashes when converting from e.g. monowhite to monowhite, which calls planarCopyWrapper() and overwrites/reads because n_bytes != n_pixels.	13 years ago
Carl Eugen Hoyos	ef3a19d595	Fix compilation with yasm-0.6.2	13 years ago
Michael Niedermayer	05577aafaa	sws: yuv2rgb asm, add memory clobber. This fixes dithering for rgb555le, it appears gcc had moved the setup of the variables after the asm or something like that. Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	13 years ago

Michael Niedermayer	bc11580007	sws: Remove unneeded YUV cliping from yuv2rgb_X_c_template() This should slightly improve speed. Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	13 years ago
Michael Niedermayer	ba6e36f906	swscale: Force full horizontal chroma internally when the output has a odd size. This fixes a gray line on the right side due to 1 column of pixels being skiped. Fixes Ticket891 Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	13 years ago
Michael Niedermayer	0644cabd7a	sws: Move yuv2rgb clipping into the tables. This fixes some cases where the clipping was entirely missing. Signed-off-by: Michael Niedermayer <michaelni@gmx.at> Thanks (for the comments and review) -to: Reimar, beastd, Ronald	13 years ago
