Michael Niedermayer	b89ce2d6af	swscale: alpha less rgb32 support. Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	13 years ago
Mans Rullgard	7c5ce99bd9	swscale: fix signed overflow in yuv2mono_X_c_template As old bits are shifted out of the accumulator, they cause signed overflows when they reach the end. Making the variable unsigned fixes this. Signed-off-by: Mans Rullgard <mans@mansr.com>	13 years ago
Michael Niedermayer	31a1342e7a	swscale: remove duplicate code from yesterdays merge. Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	13 years ago
Martin Storsjö	f32dfad9dc	swscale: Readd #define _SVID_SOURCE This was removed erroneously in `046f081b46`. This define still is necessary for getting MAP_ANONYMOUS defined on linux/glibc, despite the define reshuffling done in that commit. Without MAP_ANONYMOUS defined, the mprotect calls for setting the generated mmx2 scaler code pages executable are left out, causing crashes if that codepath is chosen. This patch fixes scaling from 192x144 to 320x240 with -sws_flags fast_bilinear, which crashes on linux at the moment. Signed-off-by: Martin Storsjö <martin@martin.st>	13 years ago

John Stebbins	09d243ddd0	swscale: Fix stack alignment for SSE Although gcc guarantees 16 byte stack alignment, threads under WinXP don't appear to be guaranteed to start stack aligned. So fix the alignment. Signed-off-by: Ronald S. Bultje <rsbultje@gmail.com>	13 years ago

Ronald S. Bultje	8283f90a52	swscale: handle unaligned buffers in yuv2plane1 The issue had been introduced in `c435653627` Signed-off-by: Luca Barbato <lu_zero@gentoo.org>	13 years ago
Sean McGovern	124e56454d	swscale: add padding to conversion buffer. Altivec does unaligned reads from this buffer in hscale_altivec_real(), and can thus read up to 16 bytes beyond the end of the buffer. Therefore, add an extra 16 bytes of padding at the end of the conversion buffer. This fixes fate-lavfi-pixfmts_scale on AltiVec-enabled builds under valgrind. Signed-off-by: Ronald S. Bultje <rsbultje@gmail.com>	13 years ago

Ronald S. Bultje	1deb08fcb6	swscale: align vertical filtersize by 2 on x86. The vertical scaler handles 2 rows at a time and thus requires alignment by 2, or else it'll read invalid memory and result in corrupt output.	13 years ago
