Michael Niedermayer	e1d9cee13d	sws: dont mess with XInc when the code needing it isnt used Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	14 years ago
Michael Niedermayer	29fb1b5a06	sws: Fix chroma init for 32bit buffers. Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	14 years ago
Ronald S. Bultje	ac9ac45aca	swscale: fix 16-bit scaling when output is 8-bits. We would use the second half of the U plane buffer, rather than the V plane buffer, to output the V plane pixels.	14 years ago
Michael Niedermayer	b5ff61695f	sws: fix uv overwrite in 32bt	14 years ago
Ronald S. Bultje	948ccdadf4	swscale: for >8bit scaling, read in native bit-depth. For 9/10bit, it means we don't have to upscale to 16bit before actual scaling or pixel format conversion, and thus a performance gain.	14 years ago
Ronald S. Bultje	5c391a161a	swscale: rename uv_off/uv_off2 to uv_off_px/byte.	14 years ago
Ronald S. Bultje	42d622fab3	swscale: fix 16-bit scaling when output is 8-bits. We would use the second half of the U plane buffer, rather than the V plane buffer, to output the V plane pixels.	14 years ago
Ronald S. Bultje	8f440223f6	swscale: disable full_chroma_int when converting to non-24/32bpp RGB. This functionality is only implemented for RGB24/32 and causes crashes otherwise.	14 years ago

Ronald S. Bultje	45f6ffe5e9	swscale: implement >8bit scaling support. This means that precision is retained when scaling between sample formats with >8 bits per component (48bit RGB, 16bit grayscale, 9/10/16bit YUV).	14 years ago

Ronald S. Bultje	dff5a83532	swscale: re-add support for non-native endianness. This works through some non-obvious hacks in utils.c.	14 years ago
Janne Grunau	3636e791ec	swscale: use SwsContext for av_log when available Signed-off-by: Diego Biurrun <diego@biurrun.de>	14 years ago
Ronald S. Bultje	103278f7b0	libavutil/swscale: YUV444P10/YUV444P9 support. Also add missing glue code for recently added YUV422P10 formats to swscale. Signed-off-by: Ronald S. Bultje <rsbultje@gmail.com>	14 years ago
Ronald S. Bultje	6d4d483eee	swscale: de-macro'ify RGB15/16/32 input functions. Inline functions are easier to read, maintain, modify and test, which justifies the slightly increased source size. This patch also adds support for non-native endianness RGB15/16 and fixes isSupportedOutput() to no longer claim that we support writing non-native RGB565/555/444.	14 years ago
Stefano Sabatini	b932eb1be6	swscale: reintroduce sws_format_name() symbol Reintroduce the internal symbol which was removed in: commit `e1197b9e17` Author: Stefano Sabatini <stefano.sabatini-lala@poste.it> Date: Sun May 29 17:57:40 2011 +0200 swscale: remove sws_format_name() Use av_get_pix_fmt_name() instead. The symbol is used by some external libs (hi libx264!), this gives time to them to use the recently added av_get_pix_fmt_name() rather than an internal symbol.	14 years ago
Ronald S. Bultje	808d8ff6bb	swscale: allocate larger buffer to handle altivec overreads. Altivec sws code intentionally overreads buffers for better performance, so we need to allocate larger buffers to handle that.	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
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

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
