Michael Niedermayer	bd141af460	swscale: Fix prototypes of *toyv12 so they can be used with planar rgb input. Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	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
Mans Rullgard	d853e571ad	ppc: fix some pointer to integer casts Use uintptr_t instead of plain int. Without this change, the comparisons will come out wrong for pointers in certain ranges. Fixes random failures on ppc64. Also fixes some compiler warnings. Signed-off-by: Mans Rullgard <mans@mansr.com>	13 years ago
Reimar Döffinger	424bcc46b5	Compile x86/swscale_template with -mno-red-zone. Replaces a very hackish hack to fix the same issue (call instruction overwriting stack variables). Signed-off-by: Reimar Döffinger <Reimar.Doeffinger@gmx.de>	13 years ago
Jean First	9569a3c9f4	Add new pix_fmt RGBA64	13 years ago
Kieran Kunhya	4d4d0e8176	Fix unnecessary shift with 9/10bit vertical scaling Signed-off-by: Diego Biurrun <diego@biurrun.de>	13 years ago
Reimar Döffinger	c928e91729	Hack around gcc 4.6 breaking asm using call. gcc 4.6 no longer decrements esp to account for local variables. Thus using call will end up overwriting some local variable. So add an extra one it can safely clobber. This is a huge hack because it's basically pure chance it works, no idea how this is supposed to be done. Fixes trac ticket #397. Signed-off-by: Reimar Döffinger <Reimar.Doeffinger@gmx.de>	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	d06c5b44cc	swscale: drop redundant code. Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	13 years ago
Michael Niedermayer	1eb8014b49	swscale: add 14bit support to the "MMX/SSE2/SSSE3/SSE4 versions for horizontal scaling" Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	13 years ago
Michael Niedermayer	7700846cf6	swscale: remove unused and forgotten file. Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	13 years ago
Ronald S. Bultje	e0c3e07387	sws: implement MMX/SSE2/SSSE3/SSE4 versions for horizontal scaling. Speed: from 3.9x to 9.6x speed improvement over C, and some small (up to 15%) speed improvements over existing MMX code (particularly for bigger filters).	13 years ago
Michael Niedermayer	27bf599350	swscale: Fix unused asm and enable it Author of the fix is ronald, the enabling & commit message are mine. This fixes commit `4e3e333a79` Author: Ronald S. Bultje <rsbultje@gmail.com> Date: Tue Jul 5 12:49:11 2011 -0700 swscale: error dithering for 16/9/10-bit to 8-bit. Based on a somewhat similar idea in FFmpeg's swscale copy. The Fix was originally commited in: (and i missed it due to the commit message) commit `5c391a161a` Author: Ronald S. Bultje <rsbultje@gmail.com> Date: Fri Jul 8 14:39:04 2011 -0700 swscale: rename uv_off/uv_off2 to uv_off_px/byte.	14 years ago
Anton Khirnov	fb4ca26bdb	lavf,lavc,sws: add {avcodec,avformat,sws}_get_class() functions.	14 years ago
Reimar Döffinger	746f1f14de	Remove unused variables. Signed-off-by: Reimar Döffinger <Reimar.Doeffinger@gmx.de>	14 years ago
Clément Bœsch	7c14c24250	sws: fix a huge amount of incompatible pointer type arguments warnings.	14 years ago
Michael Niedermayer	abe0b8e9f3	sws: use shift for chroma sample up convertion sws: use shifts for non full range luma sample upconvertion Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	14 years ago
Ronald S. Bultje	3f04ab4fcd	swscale: split hScale() function pointer into h[cy]Scale(). This allows using more specific implementations for chroma/luma, e.g. we can make assumptions on filterSize being constant, thus avoiding that test at runtime.	14 years ago
Michael Niedermayer	d9c9a0c767	sws: remove hScale16NX_c() Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	14 years ago
Michael Niedermayer	66bb5cd592	sws: remove hScale16N() and use ronalds reformated version of it. Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	14 years ago
Michael Niedermayer	3652409f5b	sws: remove unneeded code from last merge Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	14 years ago
Luca Barbato	3304a1e69a	swscale: add dithering to yuv2yuvX_altivec_real It just does that part in scalar form, I doubt using a vector store over 2 array would speed it up particularly. The function should be written to not use a scratch buffer.	14 years ago
Ronald S. Bultje	28c1115a91	swscale: use 15-bit intermediates for 9/10-bit scaling.	14 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>	14 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>	14 years ago
Stefano Sabatini	4ce0a94656	lsws: remove deprecated and unused stuff after the 0->1 major bump	14 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.	14 years ago
Ronald S. Bultje	ac0fb59348	swscale: use 15-bit intermediates for 9/10-bit scaling.	14 years ago
Kostya Shishkov	42ba12888b	Do not convert RGB buffer at once when stride does not fit exact samples. When converting RGB format to RGB format with the same bits per sample, unscaled path performs conversion on the whole buffer at once. For non-multiple-of-16 BGR24 to RGB24 conversion it means that padding at the end of line will be converted too. Since it may be of arbitrary length (e.g. 8 bytes), operating on the whole buffer produces obviously wrong results. Signed-off-by: Ronald S. Bultje <rsbultje@gmail.com>	14 years ago
