522d65ba25 rgb2rgb: remove duplicate mmx/mmx2/3dnow/sse2 functions.
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.

b6cac9b3bf swscale: remove if(full_chr_int) from yuv2packed1().
If that flag is set, swScale() already proxies the call to

commit 86330b4c92
Author: Luca Barbato <lu_zero@gentoo.org>
Date:   Wed Apr 13 20:57:30 2011 +0200

    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.

commit c003832883
Author: Luca Barbato <lu_zero@gentoo.org>
Date:   Wed Apr 13 20:57:29 2011 +0200

    swscale: move away x86 specific code from rgb2rgb

    Keep only the plain C code in the main rgb2rgb.c and move the x86
    specific optimizations to x86/rgb2rgb.c
    Change the initialization pattern a little so some of it can be
    factorized to behave more like dsputils.

1bb0f0c925 swscale: remove if(bitexact) branch from functions.
Instead, only set the function pointers if bitexact flag is

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.

In the loop:
    for (i=0; i<dstH; i++) {
        int chrI= i*c->chrDstH / dstH;

when i*c->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.

This is on a Nehalem i7.  Despite being a 500 frame, 720p video, the numbers
fluctuate, so I took an average of 4 runs.

Another reason I'd like this change is youtube accepts videos with higher
resolutions than 5120.
16384 is vp8's maximum resolution, so that should keep us amused for a
little longer.

737eb5976f Merge libavcore into libavutil
It is pretty hopeless that other considerable projects will adopt
libavutil alone in other projects. Projects that need small footprint
are better off with more specialized libraries such as gnulib or rather
just copy the necessary parts that they need. With this in mind, nobody
is helped by having libavutil and libavcore split. In order to ease
maintenance inside and around FFmpeg and to reduce confusion where to
put common code, avcore's functionality is merged (back) to avutil.

262b6dbad9 darwin: allow 64-bit darwin to allocate executable memory
darwin requires _DARWIN_C_SOURCE to be defined for MAP_ANON, which is used by
swscale to determine whether to use malloc() or mmap(). 64-bit darwin does not
have an executable heap, so mmap() must be used instead of malloc(), and
therefore _DARWIN_C_SOURCE must be defined.

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.

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.

These pixel formats are not true pixel formats but hacks specific to
JPEG in libavcodec. They are deprecated and should be removed (that is
from libavcodec first and libswscale second)...  but they must be
tested by swscale-test.
