Reinhard Tartler	5089ce1b5a	swscale: #include "libavutil/mathematics.h" this file uses the M_PI macro since `4e74187db2`, so include the correct header directly. Signed-off-by: Reinhard Tartler <siretart@tauware.de>	13 years ago
Michael Niedermayer	b89ce2d6af	swscale: alpha less rgb32 support. 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
Ronald S. Bultje	185655c601	swscale: add support for planar RGB input.	13 years ago

Michael Niedermayer	5bccb2d096	sws: handle jpeg pixel formats in sws_init_context() Fixes Ticket576 Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	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
Ronald S. Bultje	dc49bf1270	sws/pixfmt/pixdesc: add support for yuv420p9le/be.	13 years ago

Reimar Döffinger	ae23b26995	Enable conversions to YUV444P9/YUV444P10, they seem to work fine. Signed-off-by: Reimar Döffinger <Reimar.Doeffinger@gmx.de>	13 years ago
Jean First	9569a3c9f4	Add new pix_fmt RGBA64	13 years ago
Ronald S. Bultje	ea540401d6	swscale: fix byte overreads in SSE-optimized hscale(). SSE-optimized hScale() scales up to 4 pixels at once, so we need to allocate up to 3 padding pixels to prevent overreads. This fixes valgrind errors in various swscale-tests on fate.	13 years ago
Michael Niedermayer	66bb5cd592	sws: remove hScale16N() and use ronalds reformated version of it. Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	13 years ago
Ronald S. Bultje	28c1115a91	swscale: use 15-bit intermediates for 9/10-bit scaling.	13 years ago
Stefano Sabatini	6a92551234	lsws: remove optimization debug logs in sws_init_context() The logged information is possibly false, and it tends to be outdated after each change since the logging code needs to be manually updated. Simplify and prevent confusing wrong debug messages. Signed-off-by: Luca Barbato <lu_zero@gentoo.org>	13 years ago
Stefano Sabatini	347167ecf5	lsws: use array for storing the supported in/out information Also remove the unnecessary isSupportedIn/Out macros. Make the code more compact/readable, and simplify the access to lsws-specific pixel format information. Signed-off-by: Luca Barbato <lu_zero@gentoo.org>	13 years ago
Stefano Sabatini	4ce0a94656	lsws: remove deprecated and unused stuff after the 0->1 major bump	13 years ago
Ronald S. Bultje	62ee0e6a97	Revert "swscale: use 15-bit intermediates for 9/10-bit scaling." This reverts commit `ac0fb59348`. It causes valgrind errors which I'll want to investigate before resubmitting this.	13 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	8a8d0ce208	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	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	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
Stefano Sabatini	e1197b9e17	swscale: remove sws_format_name() Use av_get_pix_fmt_name() instead.	14 years ago
