Ronald S. Bultje	7f77e9041a	swscale: clip before assigning tables in RGB output functions.	13 years ago
Ronald S. Bultje	4860625236	swscale: fix off-by-one in second coefficient in bilinear filters. If coefficient A is 12-bits xixed-point number "X", then the other coefficient is (1 << 12) - X, not (1 << 12) - X - 1.	13 years ago
Ronald S. Bultje	9206ac80a5	swscale: handle last pixel if lines have an odd width. Fixes bug 270.	13 years ago
Diego Biurrun	ef0ee7f657	swscale: K&R formatting cosmetics (part II) Also adjust some comments including wording and typo fixes.	13 years ago

Henrik Gramner	729f90e268	x86inc improvements for 64-bit Add support for all x86-64 registers Prefer caller-saved register over callee-saved on WIN64 Support up to 15 function arguments Also (by Ronald S. Bultje) Fix up our asm to work with new x86inc.asm. Signed-off-by: Ronald S. Bultje <rsbultje@gmail.com> Signed-off-by: Justin Ruggles <justin.ruggles@gmail.com>	13 years ago

Diego Biurrun	e7e19b15c7	build: Only clean the architecture subdirectory we build for. This allows simplifying the Makefiles; it is no longer necessary to register arch subdirectory Makefiles, just putting them in place is enough.	13 years ago
Diego Biurrun	ad0e31f134	build: prettyprinting cosmetics	13 years ago
Ronald S. Bultje	45fdcc8e2d	swscale: convert hscale() to use named arguments.	13 years ago
Ronald S. Bultje	aba7a827aa	swscale: convert hscale to cpuflags().	13 years ago

Ronald S. Bultje	1d8c4af396	swscale: take first/lastline over/underflows into account for MMX. Fixes crashes for extremely large resizes (several 100-fold). Found-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind CC: libav-stable@libav.org	13 years ago
Ronald S. Bultje	491865b57d	swscale: fix underflows in firstline calculations for extreme resizes. Found-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind CC: libav-stable@libav.org	13 years ago

Ronald S. Bultje	1254022ea7	swscale: fix filtersize clipping. if srcW<=2, clip(x, 1, srcW-2) still allows srcW to be < 1.	13 years ago
Diego Biurrun	89d94b2182	swscale: K&R formatting cosmetics (part I)	13 years ago
Diego Biurrun	72b95764d0	swscale: variable declaration and placement cosmetics	13 years ago

Ronald S. Bultje	b18f8cbf3d	Revert two swscale commits. Revert "swscale: update context offsets after removal of AlpMmxFilter." (commit `a95e3fa90b`) and Revert "swscale: Remove some write-only variables related to alpha handling." (commit `9d03cb9fc5`). They broke alpha handling - it's the evil inline asm that still uses that variable, so it's not truely write-only.	13 years ago
Ronald S. Bultje	1bab6f852c	swscale: make access to filter data conditional on filter type. Prevents crashes on 1-tap filter (unscaled). Also rename "bguf" argument to "vbuf", seems that was a typo.	13 years ago
Ronald S. Bultje	a95e3fa90b	swscale: update context offsets after removal of AlpMmxFilter.	13 years ago
Ronald S. Bultje	25c42234a9	swscale: make monowhite/black RGB-independent. Disadvantage is that it no longer allows modifying brightness through adjustment of the RGB lookup table. Advantage is that now monowhite/black no longer need to be identified as a RGB format.	13 years ago
Diego Biurrun	9d03cb9fc5	swscale: Remove some write-only variables related to alpha handling.	13 years ago
Ronald S. Bultje	771bab7f57	swscale: fix crashes in yuv2yuvX on x86-32. They were introduced in an earlier commit that introduced use of named arguments. One cause was a typo, a second cause appears to be a bug in x264asm that I work around by not using named arguments.	13 years ago
Diego Biurrun	7331b6e718	Drop some completely unnecessary av_unused attributes.	13 years ago
Diego Biurrun	92fed11352	swscale: Remove unused variable alpMmxFilter.	13 years ago
Ronald S. Bultje	3cac475655	swscale: move YUV2PACKED16WRAPPER() macro down to where it is used.	13 years ago
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
