Ronald S. Bultje	97535ffb97	swscale: remove unused xInc/srcW arguments from hScale().	14 years ago
Ronald S. Bultje	a27db4c349	swscale: fix function declaration keywords in x86/swscale_template.c. Remove inline keyword for functions that are only called through their function pointers (and thus cannot be inlined); add av_cold keyword to init function, and use av_always_inline instead of inline for functions that must be inlined for performance reasons.	14 years ago
Ronald S. Bultje	9bcbb250e2	swscale: fix types of assembly arguments. This prevents the following compiler warnings: "warning: initialization from incompatible pointer type". Since the variables are only ever used in inline assembly, their type is actually irrelevant (so the part where it was wrong did not invoke any buggy behaviour).	14 years ago
Ronald S. Bultje	496d95c34c	swscale: move two macros that are only used once into caller. This way, they look like regular code, which is easier to understand.	14 years ago
Ronald S. Bultje	0fb5193156	swscale: reindent x86 init code.	14 years ago
Ronald S. Bultje	ca364a5b43	swscale: extract SWS_FULL_CHR_H_INT conditional into init code.	14 years ago
Ronald S. Bultje	bda9b20fa4	swscale: un-special-case yuv2yuvX16_c(). Make yuv2yuvX16_c a function pointer for yuv2yuvX(), so that the function pointer becomes bitdepth-independent.	14 years ago
Ronald S. Bultje	983260b0a4	swscale: split out x86/swscale_template.c from swscale.c.	14 years ago
Anton Khirnov	b8e893399f	sws: replace all long with int. Signed-off-by: Ronald S. Bultje <rsbultje@gmail.com>	14 years ago
Ronald S. Bultje	009f829dde	swscale: fix crash in bilinear scaling.	14 years ago
Diego Biurrun	5a5a0f1613	swscale: Remove unused variables in x86 code. libswscale/x86/swscale_template.c:2072: warning: unused variable ‘canMMX2BeUsed’ libswscale/x86/swscale_template.c:2145: warning: unused variable ‘canMMX2BeUsed’ libswscale/x86/swscale_template.c:2209: warning: unused variable ‘chrVPixBuf’ libswscale/x86/swscale_template.c:2237: warning: unused variable ‘chrVSrcPtr’	14 years ago
Ronald S. Bultje	9f5d45025e	swscale: fix non-bitexact yuv2yuv[X2]() MMX/MMX2 functions.	14 years ago
Ronald S. Bultje	e758573a88	swscale: fix compile on x86-32.	14 years ago
Ronald S. Bultje	b4a224c5e4	swscale: split chroma buffers into separate U/V planes. Preparatory step to implement support for sizes > VOFW.	14 years ago
Ronald S. Bultje	836b82e3c9	swscale: reindent h[cy]scale_fast() and updateDitherTables().	14 years ago
Ronald S. Bultje	e2bad983b5	swscale: reformat x86/swscale_template.c. Interleave macros and code so that it's easier to find the actual code that belongs to a function. Also reindent where appropriate and remove dead code.	14 years ago
Ronald S. Bultje	71d9c33c86	swscale: remove duplicate mmx/mmx2 functions if they are identical.	14 years ago
Ronald S. Bultje	acb96bc268	swscale: remove if (c->dstFormat) branch from yuv2packed[12X](). This allows cutting up the function in much smaller and easier- to-maintain chunks.	14 years ago
Ronald S. Bultje	b6cac9b3bf	swscale: remove if(full_chr_int) from yuv2packed1(). If that flag is set, swScale() already proxies the call to yuv2rgbXinC_full(). Therefore, this flag is never set when yuv2packed1() is called.	14 years ago
Ronald S. Bultje	2159a24573	swscale: remove if(accurate_rnd) branch from functions.	14 years ago
Diego Biurrun	0093199184	swscale: Remove commented-out printf cruft.	14 years ago
Ronald S. Bultje	1bb0f0c925	swscale: remove if(bitexact) branch from functions. Instead, only set the function pointers if bitexact flag is not set during initialization. Since a change in flags triggers a re-init anyway, this doesn't situations where flag values change during runtime.	14 years ago
Ronald S. Bultje	566b5fbbb3	swscale: remove if(canMMX2BeUsed) conditional. Instead, set function pointers conditionally during init. This patch also reveals a whole branch of dead assembly code that is therefore also removed.	14 years ago
Ronald S. Bultje	aaca69c130	swscale: remove swScale_{c,MMX,MMX2} duplication.	14 years ago
Ronald S. Bultje	c4fd283a46	swscale: use emms_c().	14 years ago
Ronald S. Bultje	b9eb2136af	swscale: remove dead macro WRITEBGR24OLD.	14 years ago
Ronald S. Bultje	1dd4f4be5a	swscale: remove AMD3DNOW "optimizations". The functions are identical to their MMX counterparts. Thus, pretending that swscale is highly optimized for AMD3DNOW extensions is a poorly executed practical joke at best.	14 years ago
Ronald S. Bultje	11ffefefdb	swscale: remove duplicated x86/ functions.	14 years ago
Ronald S. Bultje	e66149e714	swscale: force --enable-runtime-cpudetect and remove SWS_CPU_CAPS_*.	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
Janne Grunau	7f2ae5c7af	swscale: fix compilation with --enable-runtime-cpudetect	14 years ago
Josh Allmann	735bf19511	swscale: further cleanup swscale.c Move x86-specific constants out of swscale.c	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
Mans Rullgard	2912e87a6c	Replace FFmpeg with Libav in licence headers Signed-off-by: Mans Rullgard <mans@mansr.com>	14 years ago
Mans Rullgard	f344903ca5	Fix MMX rgb24 to yuv conversion with gcc 4.6 When built with gcc 4.6, the MMX rgb24 to yuv conversion gives wrong output. The compiler produces this warning: libswscale/swscale_template.c:1885:5: warning: use of memory input without lvalue in asm operand 4 is deprecated Changing the memory operand to a register makes it work. Signed-off-by: Mans Rullgard <mans@mansr.com>	14 years ago
Mans Rullgard	ef4a65149d	Replace ASMALIGN() with .p2align This macro has unconditionally used .p2align for a long time and serves no useful purpose.	14 years ago
Baptiste Coudurier	df0743e01e	Y400A (gray alpha) input support in libswscale Originally committed as revision 32394 to svn://svn.mplayerhq.hu/mplayer/trunk/libswscale	14 years ago
Måns Rullgård	66842fe874	swscale: fix unaligned accesses in (RGB\|BGR)32_1 to YUV conversion Originally committed as revision 32011 to svn://svn.mplayerhq.hu/mplayer/trunk/libswscale	14 years ago
Anton Mitrofanov	c85007d559	Another try at fixing swscale on win64, as per r31153. Don't change paramater passing, but instead use casts. Shouldn't affect asm output on anything other than win64. libswscale should work on win64 now. The rest of ffmpeg still isn't win64 compatible due to the issue of xmm clobbers, but swscale doesn't use any SSE. Patch by Anton Mitrofanov <BugMaster AT narod DOT ru>. Originally committed as revision 31751 to svn://svn.mplayerhq.hu/mplayer/trunk/libswscale	15 years ago
Ramiro Polla	c3ab0004ae	Revert r31153. It failed to build on: x86_64 / Mac OS X gcc 4.0.1 x86_64 / Linux icc (all) x86_64 / Linux gcc 4.0.4 x86_64 / OpenBSD gcc 3.3.5 x86_64 / Linux suncc 5.10 and there are some reports of crashes. Originally committed as revision 31170 to svn://svn.mplayerhq.hu/mplayer/trunk/libswscale	15 years ago
Ramiro Polla	d9d14dc607	Use int instead of long to pass width parameters in non-public functions. long was being incorrectly used as an x86-sized register, both for 32 and 64 bits, but this is not the case in win64. Originally committed as revision 31153 to svn://svn.mplayerhq.hu/mplayer/trunk/libswscale	15 years ago
Diego Biurrun	819ee683d8	libswscale: Relicense almost all x86 assembler optimizations as LGPL. This is of course done with permissions from the authors. The only GPL component left are MMX optimizations for YUV to RGB conversion. Originally committed as revision 30965 to svn://svn.mplayerhq.hu/mplayer/trunk/libswscale	15 years ago
Diego Biurrun	f5af8f1625	Replace wrong condition name in #endif comment by correct instance. Originally committed as revision 30938 to svn://svn.mplayerhq.hu/mplayer/trunk/libswscale	15 years ago

Ramiro Polla	f1d5a1f285	Reorder buffer debug. Also print out if slice was buffered. Originally committed as revision 30722 to svn://svn.mplayerhq.hu/mplayer/trunk/libswscale	15 years ago
Michael Niedermayer	6022255774	Use isAnyRGB() where possible Originally committed as revision 30435 to svn://svn.mplayerhq.hu/mplayer/trunk/libswscale	15 years ago
Michael Niedermayer	3b1ee70312	Rename isRGB() and isBGR() as their meaning is confusing. Originally committed as revision 30433 to svn://svn.mplayerhq.hu/mplayer/trunk/libswscale	15 years ago
Stefano Sabatini	bc45751f7f	Declare with av_unused the variable alpMmxFilter, fix the gcc warning: swscale_template.c: In function ‘swScale_C’: swscale_template.c:2580: warning: unused variable ‘alpMmxFilter’ swscale_template.c: In function ‘sws_init_swScale_C’: Originally committed as revision 30332 to svn://svn.mplayerhq.hu/mplayer/trunk/libswscale	15 years ago
Ramiro Polla	0cc854e377	Reuse h{lum,chr}Filter{,Pos} variables for MMX2 fast_bilinear horizontal scaler. Originally committed as revision 30327 to svn://svn.mplayerhq.hu/mplayer/trunk/libswscale	15 years ago
Zuxy Meng	a959e24780	Const correctness for src pointer. Remove all constness related warnings in libswscale. Originally committed as revision 30306 to svn://svn.mplayerhq.hu/mplayer/trunk/libswscale	15 years ago
