2011-06-03swscale: split swscale.c in unscaled and generic conversion routines.Ronald S. Bultje
This duplicates the function fillPlane().
2011-06-03swscale: cosmetics.Ronald S. Bultje
Remove duplicate "inC" and "_c" functions that do the same thing; give each function that handles data and acts as a function pointer a "_c" suffix; remove "_c" suffix from functions that are inherently not optimizable. Remove inline keyword from functions that are only used through function pointers.

2011-06-03swscale: reintroduce sws_format_name() symbolStefano Sabatini
Reintroduce the internal symbol which was removed in: commit e1197b9e1746c03b1d13d816d1569aeaf1b71ecc 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.
2011-06-02swscale: dither for planar yuv outputsMichael Niedermayer
Signed-off-by: Michael Niedermayer <michaelni@gmx.at>
2011-06-02swscale: Fix use of uninitialized valuesMichael Niedermayer
(bug probably introduced from a marge of libav) Signed-off-by: Michael Niedermayer <michaelni@gmx.at>
2011-06-02swscale: allocate larger buffer to handle altivec overreads.Ronald S. Bultje
Altivec sws code intentionally overreads buffers for better performance, so we need to allocate larger buffers to handle that.
2011-06-02Replace "vector const" by "const vector" otherwise gcc 4.6.0 fails.Reimar Döffinger
Given that this compiles fine with the Apple compiler that is probably a gcc bug, but "const vector" is nicer anyway.
2011-06-01swscale: fix compilation of bfin due to missing pixdesc.h headerStefano Sabatini
This is required after sws_format_name() was replaced by av_get_pix_fmt(), which is declared in libavutil/pixdesc.h.

2011-05-30Add const to fix "cast discards qualifiers" warnings.Reimar Döffinger

2011-05-30swscale: remove sws_format_name()Stefano Sabatini
Use av_get_pix_fmt_name() instead.

2011-05-28swscale: replace formatConvBuffer[VOF] by allocated array.Ronald S. Bultje
This allows to convert between formats of arbitrary width, regardless of the value of VOF/VOFW.

2011-05-28rgb2rgb: remove duplicate mmx/mmx2/3dnow/sse2 functions.Ronald S. Bultje
Many functions have such a prefix, but do not actually use any instructions or features from that set, thus giving the false impression that swscale is highly optimized for a particular system, whereas in reality it is not.
2011-05-28swscale: reindent h[cy]scale_fast() and updateDitherTables().Ronald S. Bultje
2011-05-28swscale: reformat x86/swscale_template.c.Ronald S. Bultje
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.
2011-05-28swscale: remove duplicate mmx/mmx2 functions if they are identical.Ronald S. Bultje
2011-05-28swscale: remove if (c->dstFormat) branch from yuv2packed[12X]().Ronald S. Bultje
This allows cutting up the function in much smaller and easier- to-maintain chunks.
2011-05-28swscale: remove if(full_chr_int) from yuv2packed1().Ronald S. Bultje
If that flag is set, swScale() already proxies the call to yuv2rgbXinC_full(). Therefore, this flag is never set when yuv2packed1() is called.
