Peter Belkner	502e858fd2	swscale: fix compile on mingw32 Compiling "swscale.c" breaks on MINGW32 because of multiple including "libswscale_template.c"	14 years ago
Ronald S. Bultje	76f8a96e00	[PATCH] Update pixdesc_be fate refs after adding 9/10bit YUV420P formats. Also remove code that overwrites the C versions of functions in sws_init_swScale_altivec(), so that it uses the C functions of files if no altivec-optimized version exists.	14 years ago

Diego Biurrun	046f081b46	configure: Do not unconditionally add -D_POSIX_C_SOURCE to CPPFLAGS. Adding _POSIX_C_SOURCE to CPPFLAGS globally produces all sorts of problems since it causes certain system functions to be hidden on some (BSD) systems. The solution is to only add the flag on systems that really require it, i.e. glibc-based ones. This change makes BSD systems compile out-of-the-box without the need for adding specific flags manually. It also allows dropping a number of flags set manually on a file-per-file basis, but were only present to work around breakage introduced by the presence of _POSIX_C_SOURCE. Also add _XOPEN_SOURCE to CPPFLAGS for glibc systems. We use XSI extensions in several places already, so it is preferable to define it globally instead of littering source files with individual #defines only needed for glibc.	14 years ago
Michael Niedermayer	1cafc23288	sws-PPC: fix after VOFW change. It seems sws-PPC did hardcode 2048 at various places instead of using VOFW. This also means that all past VOFW benchmarks on PPC are meaningless Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	14 years ago
Ronald S. Bultje	c8f487deae	swscale: fix YUV420P 9/10bit support. Fix handling of input if not in native endianness, and add support for 9/10-bit output. This allows us to force endianness of YUV420P 9/10bit in the H264/10bit fate tests, which should fix them on big-endian systems.	14 years ago

Michael Niedermayer	7bea13f111	swscale: Fix scaling for unscaled dithered planar convertions. This fixes some overflow in bright areas and ensures that the maximum brightness level is mapped to the maximum without cliping and without showing dither patterens in flat max brightness areas.

Oskar Arvidsson	42239ced65	Add pixel formats for 9- and 10-bit yuv420p. Also add support for these formats in libswscale. Needed for high bit depth h264 decoding. Signed-off-by: Ronald S. Bultje <rsbultje@gmail.com>	14 years ago

Michael Niedermayer	42c9bd313f	swscale: Support dither in is16BPS(c->srcFormat) && !is16BPS(c->dstFormat) This is done by just letting the Nbit code handle it, which now can do it. Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	14 years ago

Stefano Sabatini	bd2a3700c0	lsws: prevent overflow in sws_init_context() In the loop: for (i=0; i<dstH; i++) { int chrI= ic->chrDstH / dstH; when ic->chrDstH > INT_MAX this leads to an integer overflow, which results in a negative value for chrI and in out-of-buffer reads. The overflow is avoided by forcing int64_t arithmetic by casting i to int64_t. Fix crash, and trac issue #72. Signed-off-by: Stefano Sabatini <stefano.sabatini-lala@poste.it>	14 years ago

Luca Barbato	86330b4c92	swscale: partially move the arch specific code left PPC and x86 code is split off from swscale_template.c. Lots of code is still duplicated and should be removed later. Again uniformize the init system to be more similar to the dsputil one. Unset h*scale_fast in the x86 init in order to make the output consistent with the previous status. Thanks to Josh for spotting it.	14 years ago
Luca Barbato	c003832883	swscale: move away x86 specific code from rgb2rgb Keep only the plain C code in the main rgb2rgb.c and move the x86 specific optimizations to x86/rgb2rgb.c Change the initialization pattern a little so some of it can be factorized to behave more like dsputils.	14 years ago
