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	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

Michael Niedermayer	5ab6f0fe5a	Revert "swscale: fix integer overflows in RGB pixel writing." This reverts commit `77d88b872d`. The revert fixes actual overflows and a segfault as the variables are signed and can be negative. Conflicts: libswscale/swscale.c Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	13 years ago

Ronald S. Bultje	9ea3501d87	swscale: don't show full-chroma-int warning for non-RGB output. Non-RGB output always uses full chroma interpolation.	13 years ago
Ronald S. Bultje	d49352c7cc	swscale: fix overflows in vertical scaling at top/bottom edges. This fixes integer multiplication overflows in RGB48 output (vertical) scaling as detected by IOC. What happens is that for certain types of filters (lanczos, spline, bicubic), the intermediate sum of coefficients in the middle of a filter can be larger than the fixed-point equivalent of 1.0, even if the final sum is 1.0. This is fine and we support that. However, at frame edges, initFilter() will merge the coefficients for the off-screen pixels into the top or bottom pixel, such as to emulate edge extension. This means that suddenly, a single coefficient can be larger than the fixed-point equivalent of 1.0, which the vertical scaling routines do not support. Therefore, remove the merging of coefficients for edges for the vertical scaling filter, and instead add edge detection to the scaler itself so that it copies the pointers (not data) for the edges (i.e. it uses line[0] for line[-1] as well), so that a single coefficient is never larger than the fixed-point equivalent of 1.0.	13 years ago
Ronald S. Bultje	72dafea0fc	swscale: fix overflow in gray16 vertical scaling. This fixes the same overflow as in the RGB48/16-bit YUV scaling; some filters can overflow both negatively and positively (e.g. spline/lanczos), so we bias a signed integer so it's "half signed" and "half unsigned", and can cover overflows in both directions while maintaining full 31-bit depth.

Mans Rullgard	77d88b872d	swscale: fix integer overflows in RGB pixel writing. We're shifting individual components (8-bit, unsigned) left by 24, so making them unsigned should give the same results without the overflow. Signed-off-by: Ronald S. Bultje <rsbultje@gmail.com>	13 years ago
