Xi Wang	f73f76fd20	swscale: fix NULL checking in sws_alloc_context() sws_getCachedContext() and sws_getContext() expect sws_alloc_context() to return NULL when out of memory, as follows. if (!(context = sws_alloc_context())) return NULL; This patch fixes sws_alloc_context() to return NULL in that case.

Michael Niedermayer	8edf9b1fa4	sws: rgb has no range, avoid random results if the user tries to mess with it anyway. Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	12 years ago

Mans Rullgard	95cd815c36	swscale: try to use mmap only if available Some systems, e.g. Minix, have sys/mman.h defining MAP_ANONYMOUS without providing (working) mmap and friends. The mmx filter generation code checks only for MAP_ANONYMOUS, not for availability of mmap itself which leads to build errors on aforementioned systems. This changes the conditional compilation to use mmap only if all the required functions are available. Signed-off-by: Mans Rullgard <mans@mansr.com>	12 years ago

Martin Storsjö	75c37c5ace	swscale: Provide the right alignment for external mmx asm This reverts parts of `e0c6cce447`. There is external mmx asm that requires this alignment. This fixes crashes when using swscale in builds with external mmx, without inline assembly. Signed-off-by: Martin Storsjö <martin@martin.st>	12 years ago
Diego Biurrun	e0c6cce447	x86: Replace checks for CPU extensions and flags by convenience macros This separates code relying on inline from that relying on external assembly and fixes instances where the coalesced check was incorrect.	12 years ago
Diego Biurrun	17337f54c0	x86: Split inline and external assembly #ifdefs	12 years ago
Mans Rullgard	c318626ce2	x86: rename libavutil/x86_cpu.h to libavutil/x86/asm.h This puts x86-specific things in the x86/ subdirectory where they belong. Signed-off-by: Mans Rullgard <mans@mansr.com>	12 years ago
Diego Biurrun	239fdf1b4a	x86: build: replace mmx2 by mmxext Refactoring mmx2/mmxext YASM code with cpuflags will force renames. So switching to a consistent naming scheme beforehand is sensible. The name "mmxext" is more official and widespread and also the name of the CPU flag, as reported e.g. by the Linux kernel.	12 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
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
