* swscale-test: fix stack overread.Ronald S. Bultje2012-01-12
| | | | | Fixes problems in swscale-test where it gives a 3-member array to a function expecting a 4-member array.
* swscale: fix invalid conversions and memory problems.Ronald S. Bultje2012-01-12
| | | | | | | | | | 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.

* swscale: fix overflows in vertical scaling at top/bottom edges.Ronald S. Bultje2011-12-18
| | | | | | | | | | | | | | | | | | | | | | 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.
* swscale: fix overflow in gray16 vertical scaling.Ronald S. Bultje2011-12-17
| | | | | | | | | | 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.

* swscale: fix integer overflows in RGB pixel writing.Mans Rullgard2011-12-17
| | | | | | | | 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>
* swscale: add endian conversion for RGB555 and RGB444 pixel formatsJanne Grunau2011-12-17
| | | | Add a macro to shorten the if condition.
* swscale: fix overflows in output of RGB48 pixels.Ronald S. Bultje2011-12-17
| | | | | | | | | | | | | | For certain types of filters where the intermediate sum of coefficients can go above the fixed-point equivalent of 1.0 in the middle of a filter, the sum of a 31-bit calculation can overflow in both directions and can thus not be represented in a 32-bit signed or unsigned integer. To work around this, we subtract 0x40000000 from a signed integer base, so that we're halfway signed/unsigned, which makes it fit even if it overflows. After the filter finishes, we add the scaled bias back after a shift. We use the same trick for 16-bit bpc YUV output routines. Signed-off-by: Mans Rullgard <mans@mansr.com>

* swscale: fix signed overflow in yuv2mono_X_c_templateMans Rullgard2011-11-26

* swscale: Readd #define _SVID_SOURCEMartin Storsjö2011-11-25
| | | | | | | | | | | | | | | | | This was removed erroneously in 046f081b46c8479820409cf8f530b988221bd15b. 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>
