Subject: [PATCH] ARM: Faster NEON yuv->rgb conversion for Krait and Cortex-A15

The older code was developed and tested only on ARM Cortex-A8 and ARM Cortex-A9.
Tuning it for newer ARM processors can introduce some speed-up (up to 20%).

The performance of the inner loop (conversion of 8 pixels) improves from
~27 cycles down to ~22 cycles on Qualcomm Krait 300, and from ~20 cycles
down to ~18 cycles on ARM Cortex-A15.

The performance remains exactly the same on ARM Cortex-A7 (~58 cycles),
ARM Cortex-A8 (~25 cycles) and ARM Cortex-A9 (~30 cycles) processors.

Also use larger indentation in the source code for separating two independent
instruction streams.

Subject: [PATCH] ARM: NEON optimized yuv->rgb565 conversion

The performance of the inner loop (conversion of 8 pixels):
* ARM Cortex-A7:  ~55 cycles
* ARM Cortex-A8:  ~28 cycles
* ARM Cortex-A9:  ~32 cycles
* ARM Cortex-A15: ~20 cycles
* Qualcomm Krait: ~24 cycles

Based on the Linaro rgb565 patch from
    https://sourceforge.net/p/libjpeg-turbo/patches/24/
but implements better instructions scheduling.

f5644c3498 Ensure that tjFree() is used for any JPEG buffers that might have been dynamically allocated by the compress/transform functions. To keep things simple, we use tjAlloc() for the statically-allocated buffer as well, so that tjFree() can always be used to free the buffer, regardless of whether it was allocated by tjbench or by the TurboJPEG library. This fixes crashes that occurred on Windows when running tjunittest or tjbench with the -alloc flag.

55e328ecb8 Revert r1335 and r1336. It was a valiant effort, but on Windows, xmm8-xmm15 are non-volatile, and the overhead of pushing them onto the stack at the beginning of each function and popping them at the end was causing worse performance (in the neighborhood of 3-5%) than just using the work areas and limiting the register usage to xmm0-xmm7. Best to leave the SSE2 code alone. We can optimize the register usage for AVX2, once that port takes place.

0713c1bb54 Add a set of undocumented environment variables and Java system properties that allow compression features of libjpeg that are not normally exposed in the TurboJPEG API to be enabled. These features are not normally exposed because, for the most part, they aren't "turbo" features, but it is still useful to be able to benchmark them without modifying the code.

2e2ce5a1da .func/.endfunc are only necessary when generating STABS debug info, which basically went out of style with parachute pants and Rick Astley. At any rate, none of the platforms for which we're building the ARM code use it (DWARF is the common format these days), and the .func/.endfunc directives cause the clang integrated assembler to fail (http://llvm.org/bugs/show_bug.cgi?id=20424).

684ace1924 Extend tjbenchtest so that it tests the dynamic JPEG buffer allocation feature in TurboJPEG.

cce13c767e Subtle point, but dest->outbuffer is a pointer to the address of the JPEG buffer, which is stored in the calling program. Thus, *(dest->outbuffer) will always equal *outbuffer. We need to compare *outbuffer with dest->buffer instead to determine if the pointer is being reused.

We can't simply increase JMSG_LENGTH_MAX, because it is part of the libjpeg API, and it is generally assumed that a buffer of this length will be passed to format_message().  Thus, the easiest solution is simply to use a shorter copyright string for JMSG_COPYRIGHT.

495e43426e Allow for building the MIPS DSPr2 extensions if the host is mips-* as well as mipsel-*. The DSPr2 extensions are little endian, so we still have to check that the compiler defines __MIPSEL__ before enabling them. This paves the way for supporting big-endian MIPS, and in the near term, it allows the SIMD extensions to be built with Sourcery CodeBench.

715bb41ead Port the more accurate (and slightly faster) floating point IDCT implementation from jpeg-8a and later. New research revealed that the SSE/SSE2 floating point IDCT implementation was actually more accurate than the jpeg-6b implementation, not less, which is why its mathematical results have always differed from those of the jpeg-6b implementation. This patch brings the accuracy of the C code in line with that of the SSE/SSE2 code.

In order to prevent object name conflicts, it is necessary to use the subdir-objects automake directive, but it simply doesn't work right on some of the versions of automake we still have to support. Another option would be to add a separate Makefile.am file to each subdirectory, but that requires maintaining a completely different set of build rules for each one. Fortunately, however, we're in the 21st century now, so we can use filenames longer than 8.3.

e5eaf37440 Convert tabs to spaces in the libjpeg code and the SIMD code (TurboJPEG retains the use of tabs for historical reasons. They were annoying in the libjpeg code primarily because they were not consistently used and because they were used to format as well as indent the code. In the case of TurboJPEG, tabs are used just to indent the code, so even if the editor assumes a different tab width, the code will still be readable.)

b0a9cca1e3 Replace our custom version of Android.mk with instructions on how to build a libjpeg-turbo SDK for Android using autotools. Upon consulting with AOSP, it appears that Android.mk isn't really necessary except when building libjpeg-turbo for use by the Android platform itself, and it makes more sense for them to maintain the makefile for that purpose rather than for it to be upstreamed. ndk-build has serious limitations that prevent it from being used to generate static libjpeg-turbo libraries (mainly, it isn't possible to combine pre-built objects from one module into a static library for another module, which is necessary because the SIMD extensions sometimes have to be built with different CFLAGS than the rest of the code.) In general, it's just better not to introduce a new build system.

ff6961f3d2 This patch accomplishes the following:
-- Auto-generates HAVE_LOCALE_H macro and adds it to jconfig.h (this is used by rdjpgcom.c.)
-- Reconciles the description and ordering of macros between config.h.in and jconfig.h.in, so the two files can be easily diffed.
-- Eliminates the use of the autoheader-generated config.h in the project and moves relevant internal-only macros into a new file, jconfigint.h.  This is to avoid "already defined" warnings in files that were including both config.h (to get the internal autotools package information or the INLINE definition) and jconfig.h.

beb0b33764 Work around an issue in Visual C++ 2010 and 2013 that was causing the 256-bit bitmap test in the regression tests to fail. More specifically, when optimization is enabled in these versions of Visual C++, the optimizer seems to get confused by the following code block:
delta = cur0 * 2;
       cur0 += delta;          /* form error * 3 */
       errorptr[0] = (FSERROR) (bpreverr0 + cur0);
       cur0 += delta;          /* form error * 5 */
       bpreverr0 = belowerr0 + cur0;
       cur0 += delta;          /* form error * 7 */

Each time cur0 is incremented by delta, the compiled code doubles the value of delta (WTF?!)  Thus, by the time the end of the block is reached, cur0 is equal to 15 times its former self, not 7 times its former self as it should be.  At any rate, it was a lot simpler to just refactor the code so that it uses multiplication.

b53f410228 Actually, the issue with nightshot_iso_100 is unrelated to the image size. Reducing the size to 128x95, the same size as vgl_6548_0026, does not eliminate the problem. The issue seems to always occur when decompression scaling is enabled. It is unclear at this point whether this is a bug or expected behavior, but the pixels generated by the split decompression functions appear correct. They are just slightly different (but not visibly so) from the pixels generated by the monolithic decompression function.

7d9f758e52 For now, punt on trying to support fancy upsampling in tjDecodeYUV(). Fancy upsampling requires context rows and other refinements, which are difficult to implement correctly with the algorithm we're using. Longer-term, supporting fancy upsampling would probably require using the main buffer that libjpeg allocates.

c90144950f When tjDecodeYUV() is used with a "fresh" decompressor instance (one that hasn't been previously used to decompress a JPEG image), then it needs comps_in_scan, data_precision, and the quantization tables to be defined. This patch also extends TJUnitTest to check for this error.

20e158dcb7 Silence valgrind false positives about uninitialized values. Even with this patch, valgrind still complains about uninitialized values when decompressing or decoding to a buffer with an alpha-enabled colorspace. Not sure why this happens, but it occurs in libjpeg-turbo 1.3 as well, and only when the x86/x86-64 SIMD code is being used. It is my belief that these remaining warnings are also false positives, because if the output buffer is memset to all 0's prior to invoking tjDecodeYUV()/tjDecompress(), no errors are reported. If any of the alpha channel bits were in fact not being initialized, then they would still be 0 after invoking tjDecodeYUV()/tjDecompress(), and TJUnitTest would report an error.

e163653f99 Back-port code from jpeg-8 that removes unpopulated (and unneeded) tables for AC and DC coefficients when generating progressive JPEG files with arithmetic coding. This should make such files bitwise compatible with jpeg-8, barring any other mathematical differences (such as the different subsampling algorithm used in jpeg-8.) Add regression tests for progressive+arithmetic JPEG files.

07e982d9b4 Deprecate and undocument the FORCE{MMX|SSE|SSE2|SSE3} flags. These were originally introduced in TurboJPEG/IPP as a way to override the automatic CPU selection in the underlying IPP codec, which was closed source. They are not meaningful anymore, since libjpeg-turbo provides environment variables to accomplish the same thing and since it no longer necessarily uses x86 SIMD code behind the scenes.

JFREAD(), which wraps fread(), will never return -1. fread() will instead return 0 or a short object count if an error occurs, and ferror() will return 1 in that case. The second issue was that we were assigning the return value of ftell() to an unsigned long prior to checking the value, so the value would never be < 0 if an error occurred. It would instead be (unsigned long)-1.

4d877931ab In the Windows installer packages, place a duplicate copy of turbojpeg.dll in c:\libjpeg-turbo[-gcc][64]\bin. This is mainly to give installers an easy way to find the DLL for the purposes of bundling it. Specifically, this was necessary for TurboVNC, becuase 32-bit CMake running on 64-bit Windows cannot ever access the "real" c:\windows\system32 directory.

4c17a453d1 Fix I/O suspension. This little nugget of code was introduced in r30 as part of an early attempt to make buffered I/O work with the optimized Huffman codec. Ultimately, r32 reverted a lot of that mess and introduced much of the logic we now use, rendering this code unnecessary, but it was never reverted because it only causes problems when I/O suspension is used, and apparently no one has tried to do that with libjpeg-turbo until now.

441308cffa Move the TurboJPEG DLLs back into the system directory on Windows platforms. For Windows, it doesn't really simplify the build system to install these libraries in c:\libjpeg-turbo*, and it introduces potential problems with loading the JNI library. Specifically, if a user linked their Java app against the 64-bit libjpeg-turbo SDK and then used a 32-bit JVM at run time, they would not be able to load the 32-bit turbojpeg.dll without manipulating java.library.path or the PATH environment (and vice versa for building against the 32-bit libjpeg-turbo SDK and using a 64-bit JVM at run time.)

7175e51792 Further enhancements/fixes to the packaging system:
-- The Mac and Cygwin packages will now be created with the directory structure defined by the configure variables "prefix", "bindir", "libdir", etc., with the exception that the docs are always installed under /usr/share/doc/{package_name}-{version} on Cygwin and /Library/Documentation/{package_name} on Mac.
-- Fixed a duplicate filename warning when generating RPMs with the default prefix of /opt/libjpeg-turbo.
-- Moved the TurboJPEG libraries out of the system directory on Windows and Mac.  It is no longer necessary to put them there, since we are not trying to be backward compatible with TurboJPEG/IPP anymore.
-- Fixed an issue whereby building the "installer" target on Windows would not build the Java JAR file, thus causing an error if the JAR had not been previously built.
-- Building the "install" target on Windows will now install libjpeg-turbo into c:\libjpeg-turbo[-gcc][64] (the same directories used by the installers.)  This can be overridden by setting CMAKE_INSTALL_PREFIX.
-- The Java classes on all platforms will now look for the JNI library in the directory under which the build/packaging system installs it.

764e1e23aa Overhaul Linux/Unix packaging system, primarily to avoid conflicts with vendor-supplied libjpeg-turbo packages (such as in Fedora and RHEL 6.) This also streamlines the packaging system somewhat, since it is no longer necessary to move the TurboJPEG libraries into the system library directory. Relocating those libraries was originally done to provide backward compatibility with TurboJPEG/IPP, but that package is long obsolete, and the software that formerly used it has been linking statically with libjpeg-turbo for quite some time.
If the default prefix (/opt/libjpeg-turbo) is used, then we now always install 32-bit libraries in /opt/libjpeg-turbo/lib32 and 64-bit libraries in /opt/libjpeg-turbo/lib64 instead of trying to conform to the Debian or Red Hat conventions.  The RPM and DEB packages will now be created with the directory structure defined by the configure variables "prefix", "bindir", "libdir", etc., with the exception that the docs are always installed under /usr/share/doc/{package_name}-{version}.

e2394fc58a Subtle point, but the libjpeg v7+ API is not backward incompatible. That is, programs that were built against jpeg-6b can still build against jpeg-7+ with no issues. It's only the ABI that is backward incompatible, so the primary justification for implementing the emulation feature was to provide run-time (ABI) compatibility.

1.4 pre-beta
============
[1] New features in the TurboJPEG API:
-- YUV planar images can now be generated with an arbitrary line padding
(previously only 4-byte padding, which was compatible with X Video, was
supported.)
-- The decompress-to-YUV function has been extended to support image scaling.
-- JPEG images can now be compressed from YUV planar source images.
-- YUV planar images can now be decoded into RGB or grayscale images.
-- 4:1:1 subsampling is now supported. This is mainly included for
compatibility, since 4:1:1 is not fully accelerated in libjpeg-turbo and has no
significant advantages relative to 4:2:0.
-- CMYK images are now supported. This feature allows CMYK source images to be
compressed to YCCK JPEGs and YCCK or CMYK JPEGs to be decompressed to CMYK
destination images. Conversion between CMYK/YCCK and RGB or YUV images is not
supported. Such conversion requires a color management system and is thus out
of scope for a codec library.
-- The handling of YUV images in the Java API has been significantly refactored
and should now be much more intuitive.
-- The Java API now supports encoding a YUV image from an arbitrary position in
a large image buffer.
-- All of the YUV functions now have a corresponding function that operates on
separate image planes instead of a unified image buffer. This allows for
compressing/decoding from or decompressing/encoding to a subregion of a larger
YUV image. It also allows for handling YUV formats that swap the order of the
U and V planes.
[2] Added SIMD acceleration for DSPr2-capable MIPS platforms. This speeds up
the compression of full-color JPEGs by 70-80% on such platforms and
decompression by 25-35%.
[3] If an application attempts to decompress a Huffman-coded JPEG image whose
header does not contain Huffman tables, libjpeg-turbo will now insert the
default Huffman tables. In order to save space, many motion JPEG video frames
are encoded without the default Huffman tables, so these frames can now be
successfully decompressed by libjpeg-turbo without additional work on the part
of the application. An application can still override the Huffman tables, for
instance to re-use tables from a previous frame of the same video.
[4] The Mac packaging system now uses pkgbuild and productbuild rather than
PackageMaker (which is obsolete and no longer supported.) This means that
OS X 10.6 "Snow Leopard" or later must be used when packaging libjpeg-turbo,
although the packages produced can be installed on OS X 10.5 "Leopard" or
later. OS X 10.4 "Tiger" is no longer supported.
[5] The Huffman encoder now uses clz and bsr instructions for bit counting on
ARM platforms rather than a lookup table. This reduces the memory footprint
by 64k, which may be important for some mobile applications. Out of four
Android devices that were tested, two demonstrated a small overall performance
loss (~3-4% on average) with ARMv6 code and a small gain (also ~3-4%) with
ARMv7 code when enabling this new feature, but the other two devices
demonstrated a significant overall performance gain with both ARMv6 and ARMv7
code (~10-20%) when enabling the feature. Actual mileage may vary.
[6] Worked around an issue with Visual C++ 2010 and later that caused incorrect
pixels to be generated when decompressing a JPEG image to a 256-color bitmap,
if compiler optimization was enabled when libjpeg-turbo was built. This caused
the regression tests to fail when doing a release build under Visual C++ 2010
and later.
[7] Improved the accuracy and performance of the non-SIMD implementation of the
floating point inverse DCT (using code borrowed from libjpeg v8a and later.)
The accuracy of this implementation now matches the accuracy of the SSE/SSE2
implementation. Note, however, that the floating point DCT/IDCT algorithms are
mainly a legacy feature. They generally do not produce significantly better
accuracy than the slow integer DCT/IDCT algorithms, and they are quite a bit
slower.
[8] Added a new output colorspace (JCS_RGB565) to the libjpeg API that allows
for decompressing JPEG images into RGB565 (16-bit) pixels. If dithering is not
used, then this code path is SIMD-accelerated on ARM platforms.
[9] Numerous obsolete features, such as support for non-ANSI compilers and
support for the MS-DOS memory model, were removed from the libjpeg code,
greatly improving its readability and making it easier to maintain and extend.
[10] Fixed a segfault that occurred when calling output_message() with msg_code
set to JMSG_COPYRIGHT.
[11] Fixed an issue whereby wrjpgcom was allowing comments longer than 65k
characters to be passed on the command line, which was causing it to generate
incorrect JPEG files.
[12] Fixed a bug in the build system that was causing the Windows version of
wrjpgcom to be built using the rdjpgcom source code.
[13] Restored 12-bit-per-component JPEG support. A 12-bit version of
libjpeg-turbo can now be built by passing an argument of --with-12bit to
configure (Unix) or -DWITH_12BIT=1 to cmake (Windows.) 12-bit JPEG support is
included only for convenience. Enabling this feature disables all of the
performance features in libjpeg-turbo, as well as arithmetic coding and the
TurboJPEG API. The resulting library still contains the other libjpeg-turbo
features (such as the colorspace extensions), but in general, it performs no
faster than libjpeg v6b.
[14] Added ARM 64-bit SIMD acceleration for the YCC-to-RGB color conversion
and IDCT algorithms (both are used during JPEG decompression.) For unknown
reasons (probably related to clang), this code cannot currently be compiled for
iOS.
[15] Fixed an extremely rare bug that could cause the Huffman encoder's local
buffer to overrun when a very high-frequency MCU is compressed using quality
100 and no subsampling, and when the JPEG output buffer is being dynamically
resized by the destination manager. This issue was so rare that, even with a
test program specifically designed to make the bug occur (by injecting random
high-frequency YUV data into the compressor), it was reproducible only once in
about every 25 million iterations.
[16] Fixed an oversight in the TurboJPEG C wrapper: if any of the JPEG
compression functions was called repeatedly with the same
automatically-allocated destination buffer, then TurboJPEG would erroneously
assume that the jpegSize parameter was equal to the size of the buffer, when in
fact that parameter was probably equal to the size of the most recently
compressed JPEG image. If the size of the previous JPEG image was not as large
as the current JPEG image, then TurboJPEG would unnecessarily reallocate the
destination buffer.
1.3.1
=====
[1] On Un*x systems, 'make install' now installs the libjpeg-turbo libraries
into /opt/libjpeg-turbo/lib32 by default on any 32-bit system, not just x86,
and into /opt/libjpeg-turbo/lib64 by default on any 64-bit system, not just
x86-64. You can override this by overriding either the 'prefix' or 'libdir'
configure variables.
[2] The Windows installer now places a copy of the TurboJPEG DLLs in the same
directory as the rest of the libjpeg-turbo binaries. This was mainly done
to support TurboVNC 1.3, which bundles the DLLs in its Windows installation.
When using a 32-bit version of CMake on 64-bit Windows, it is impossible to
access the c:\WINDOWS\system32 directory, which made it impossible for the
TurboVNC build scripts to bundle the 64-bit TurboJPEG DLL.
[3] Fixed a bug whereby attempting to encode a progressive JPEG with arithmetic
entropy coding (by passing arguments of -progressive -arithmetic to cjpeg or
jpegtran, for instance) would result in an error, "Requested feature was
omitted at compile time".
[4] Fixed a couple of issues whereby malformed JPEG images would cause
libjpeg-turbo to use uninitialized memory during decompression.
[5] Fixed an error ("Buffer passed to JPEG library is too small") that occurred
when calling the TurboJPEG YUV encoding function with a very small (< 5x5)
source image, and added a unit test to check for this error.
[6] The Java classes should now build properly under Visual Studio 2010 and
later.
[7] Fixed an issue that prevented SRPMs generated using the in-tree packaging
tools from being rebuilt on certain newer Linux distributions.
[8] Numerous minor fixes to eliminate compilation and build/packaging system
warnings, fix cosmetic issues, improve documentation clarity, and other general
source cleanup.
1.3.0
=====
[1] 'make test' now works properly on FreeBSD, and it no longer requires the
md5sum executable to be present on other Un*x platforms.
[2] Overhauled the packaging system:
-- To avoid conflict with vendor-supplied libjpeg-turbo packages, the
official RPMs and DEBs for libjpeg-turbo have been renamed to
"libjpeg-turbo-official".
-- The TurboJPEG libraries are now located under /opt/libjpeg-turbo in the
official Linux and Mac packages, to avoid conflict with vendor-supplied
packages and also to streamline the packaging system.
-- Release packages are now created with the directory structure defined
by the configure variables "prefix", "bindir", "libdir", etc. (Un*x) or by the
CMAKE_INSTALL_PREFIX variable (Windows.) The exception is that the docs are
always located under the system default documentation directory on Un*x and Mac
systems, and on Windows, the TurboJPEG DLL is always located in the Windows
system directory.
-- To avoid confusion, official libjpeg-turbo packages on Linux/Unix platforms
(except for Mac) will always install the 32-bit libraries in
/opt/libjpeg-turbo/lib32 and the 64-bit libraries in /opt/libjpeg-turbo/lib64.
-- Fixed an issue whereby, in some cases, the libjpeg-turbo executables on Un*x
systems were not properly linking with the shared libraries installed by the
same package.
-- Fixed an issue whereby building the "installer" target on Windows when
WITH_JAVA=1 would fail if the TurboJPEG JAR had not been previously built.
-- Building the "install" target on Windows now installs files into the same
places that the installer does.
[3] Fixed a Huffman encoder bug that prevented I/O suspension from working
properly.

necessary to do so, because TurboJPEG uses versioned symbols, and if a function
changes in an ABI-incompatible way, that function is renamed and a legacy
function is provided to maintain backward compatibility. However, certain
Linux distro maintainers will blindly reject any library that is not versioned,

This package contains C software to implement JPEG image encoding, decoding,

======================
Installation Directory
======================
This document assumes that libjpeg-turbo will be installed in the default
directory (/opt/libjpeg-turbo on Un*x and Mac systems and
c:\libjpeg-turbo[-gcc][64] on Windows systems. If your installation of
libjpeg-turbo resides in a different directory, then adjust the instructions
accordingly.
=============================
Replacing libjpeg at Run Time
=============================
Un*x
----
If a Un*x application is dynamically linked with libjpeg, then you can replace
libjpeg with libjpeg-turbo at run time by manipulating LD_LIBRARY_PATH.
For instance:
[Using libjpeg]
> time cjpeg <vgl_5674_0098.ppm >vgl_5674_0098.jpg
real 0m0.392s
user 0m0.074s
sys 0m0.020s
[Using libjpeg-turbo]
> export LD_LIBRARY_PATH=/opt/libjpeg-turbo/{lib}:$LD_LIBRARY_PATH
> time cjpeg <vgl_5674_0098.ppm >vgl_5674_0098.jpg
real 0m0.109s
user 0m0.029s
sys 0m0.010s
({lib} = lib32 or lib64, depending on whether you wish to use the 32-bit or the
64-bit version of libjpeg-turbo.)
System administrators can also replace the libjpeg symlinks in /usr/lib* with
links to the libjpeg-turbo dynamic library located in /opt/libjpeg-turbo/{lib}.
This will effectively accelerate every application that uses the libjpeg
dynamic library on the system.
Windows
-------
If a Windows application is dynamically linked with libjpeg, then you can
replace libjpeg with libjpeg-turbo at run time by backing up the application's
copy of jpeg62.dll, jpeg7.dll, or jpeg8.dll (assuming the application has its
own local copy of this library) and copying the corresponding DLL from
libjpeg-turbo into the application's install directory. The official
libjpeg-turbo binary packages only provide jpeg62.dll. If the application uses
jpeg7.dll or jpeg8.dll instead, then it will be necessary to build
libjpeg-turbo from source (see "libjpeg v7 and v8 API/ABI Emulation" below.)
The following information is specific to the official libjpeg-turbo binary
packages for Visual C++:
-- jpeg62.dll requires the Visual C++ 2008 C run-time DLL (msvcr90.dll).
msvcr90.dll ships with more recent versions of Windows, but users of older
Windows releases can obtain it from the Visual C++ 2008 Redistributable
Package, which is available as a free download from Microsoft's web site.
-- Features of the libjpeg API that require passing a C run-time structure,
such as a file handle, from an application to the library will probably not
work with jpeg62.dll, unless the application is also built to use the Visual
C++ 2008 C run-time DLL. In particular, this affects jpeg_stdio_dest() and
jpeg_stdio_src().
Mac
---
Mac applications typically embed their own copies of the libjpeg dylib inside
the (hidden) application bundle, so it is not possible to globally replace
libjpeg on OS X systems. Replacing the application's version of the libjpeg
dylib would generally involve copying libjpeg.*.dylib from libjpeg-turbo into
the appropriate place in the application bundle and using install_name_tool to
repoint the libjpeg-turbo dylib to its new directory. This requires an
advanced knowledge of OS X and would not survive an upgrade or a re-install of
the application. Thus, it is not recommended for most users.
========================================
Using libjpeg-turbo in Your Own Programs
========================================
For the most part, libjpeg-turbo should work identically to libjpeg, so in
most cases, an application can be built against libjpeg and then run against
libjpeg-turbo. On Un*x systems and Cygwin, you can build against libjpeg-turbo
instead of libjpeg by setting
CPATH=/opt/libjpeg-turbo/include
and
LIBRARY_PATH=/opt/libjpeg-turbo/{lib}
({lib} = lib32 or lib64, depending on whether you are building a 32-bit or a
64-bit application.)
If using MinGW, then set
CPATH=/c/libjpeg-turbo-gcc[64]/include
and
LIBRARY_PATH=/c/libjpeg-turbo-gcc[64]/lib
Building against libjpeg-turbo is useful, for instance, if you want to build an
application that leverages the libjpeg-turbo colorspace extensions (see below.)
On Un*x systems, you would still need to manipulate LD_LIBRARY_PATH or create
appropriate symlinks to use libjpeg-turbo at run time. On such systems, you
can pass -R /opt/libjpeg-turbo/{lib} to the linker to force the use of
libjpeg-turbo at run time rather than libjpeg (also useful if you want to
leverage the colorspace extensions), or you can link against the libjpeg-turbo
static library.
To force a Un*x or MinGW application to link against the static version of
libjpeg-turbo, you can use the following linker options:
-Wl,-Bstatic -ljpeg -Wl,-Bdynamic
On OS X, simply add /opt/libjpeg-turbo/lib/libjpeg.a to the linker command
line.
To build Visual C++ applications using libjpeg-turbo, add
c:\libjpeg-turbo[64]\include to the system or user INCLUDE environment
variable and c:\libjpeg-turbo[64]\lib to the system or user LIB environment
variable, and then link against either jpeg.lib (to use the DLL version of
libjpeg-turbo) or jpeg-static.lib (to use the static version of libjpeg-turbo.)

For the most part, libjpeg-turbo should produce identical output to libjpeg
v6b. The one exception to this is when using the floating point DCT/IDCT, in
which case the outputs of libjpeg v6b and libjpeg-turbo are not guaranteed to
be identical (the accuracy of the floating point DCT/IDCT is constant when
using libjpeg-turbo's SIMD extensions, but otherwise, it can depend heavily on
the compiler and compiler settings.)
which case the outputs of libjpeg v6b and libjpeg-turbo can differ for the
following reasons:
-- The SSE/SSE2 floating point DCT implementation in libjpeg-turbo is ever so
slightly more accurate than the implementation in libjpeg v6b, but not by
any amount perceptible to human vision (generally in the range of 0.01 to
0.08 dB gain in PNSR.)
-- When not using the SIMD extensions, libjpeg-turbo uses the more accurate
(and slightly faster) floating point IDCT algorithm introduced in libjpeg
v8a as opposed to the algorithm used in libjpeg v6b. It should be noted,
however, that this algorithm basically brings the accuracy of the floating
point IDCT in line with the accuracy of the slow integer IDCT. The floating
point DCT/IDCT algorithms are mainly a legacy feature, and they do not
produce significantly more accuracy than the slow integer algorithms (to put
numbers on this, the typical difference in PNSR between the two algorithms
is less than 0.10 dB, whereas changing the quality level by 1 in the upper
range of the quality scale is typically more like a 1.0 dB difference.)
-- When not using the SIMD extensions, then the accuracy of the floating point
DCT/IDCT can depend on the compiler and compiler settings.

.TP
.B \-dct fast
Use fast integer DCT (less accurate).
In libjpeg-turbo, the fast method is generally about 5-15% faster than the int
method when using the x86/x86-64 SIMD extensions (results may vary with other
SIMD implementations, or when using libjpeg-turbo without SIMD extensions.)
For quality levels of 90 and below, there should be little or no perceptible
difference between the two algorithms. For quality levels above 90, however,
the difference between the fast and the int methods becomes more pronounced.
With quality=97, for instance, the fast method incurs generally about a 1-3 dB
loss (in PSNR) relative to the int method, but this can be larger for some
images. Do not use the fast method with quality levels above 97. The
algorithm often degenerates at quality=98 and above and can actually produce a
more lossy image than if lower quality levels had been used. Also, in
libjpeg-turbo, the fast method is not fully accelerated for quality levels
above 97, so it will be slower than the int method.
.TP
.B \-dct float
Use floating-point DCT method.
The float method is very slightly more accurate than the int method, but is
much slower unless your machine has very fast floating-point hardware. Also
note that results of the floating-point method may vary slightly across
machines, while the integer methods should give the same results everywhere.
The fast integer method is much less accurate than the other two.
The float method is mainly a legacy feature. It does not produce significantly
more accurate results than the int method, and it is much slower. The float
method may also give different results on different machines due to varying
roundoff behavior, whereas the integer methods should give the same results on
all machines.

Multi-word names should be written in lower case with underscores, e.g.,
multi_word_name (not multiWordName). Preprocessor symbols and enum constants
are similar but upper case (MULTI_WORD_NAME). Names should be unique within
the first fifteen characters. (On some older systems, global names must be
unique within six characters. We accommodate this without cluttering the
source code by using macros to substitute shorter names.)
We use function prototypes everywhere; we rely on automatic source code
transformation to feed prototype-less C compilers. Transformation is done
by the simple and portable tool 'ansi2knr.c' (courtesy of Ghostscript).
ansi2knr is not very bright, so it imposes a format requirement on function
declarations: the function name MUST BEGIN IN COLUMN 1. Thus all functions

ansi2knr does not transform method declarations (function pointers in
structs). We handle these with a macro JMETHOD, defined as
#ifdef HAVE_PROTOTYPES
#define JMETHOD(type,methodname,arglist) type (*methodname) arglist
#else
#define JMETHOD(type,methodname,arglist) type (*methodname) ()

JMETHOD(void, init_entropy_encoder, (int somearg, jparms *jp));
JMETHOD(void, term_entropy_encoder, (void));
};
Note the set of parentheses surrounding the parameter list.
A similar solution is used for forward and external function declarations
(see the EXTERN and JPP macros).
If the code is to work on non-ANSI compilers, we cannot rely on a prototype
declaration to coerce actual parameters into the right types. Therefore, use
explicit casts on actual parameters whenever the actual parameter type is not
identical to the formal parameter. Beware of implicit conversions to "int".
It seems there are some non-ANSI compilers in which the sizeof() operator
is defined to return int, yet size_t is defined as long. Needless to say,
this is brain-damaged. Always use the SIZEOF() macro in place of sizeof(),
so that the result is guaranteed to be of type size_t.

macro.)

.TP
.B \-dct fast
Use fast integer DCT (less accurate).
In libjpeg-turbo, the fast method is generally about 5-15% faster than the int
method when using the x86/x86-64 SIMD extensions (results may vary with other
SIMD implementations, or when using libjpeg-turbo without SIMD extensions.) If
the JPEG image was compressed using a quality level of 85 or below, then there
should be little or no perceptible difference between the two algorithms. When
decompressing images that were compressed using quality levels above 85,
however, the difference between the fast and int methods becomes more
pronounced. With images compressed using quality=97, for instance, the fast
method incurs generally about a 4-6 dB loss (in PSNR) relative to the int
method, but this can be larger for some images. If you can avoid it, do not
use the fast method when decompressing images that were compressed using
quality levels above 97. The algorithm often degenerates for such images and
can actually produce a more lossy output image than if the JPEG image had been
compressed using lower quality levels.
.TP
.B \-dct float
Use floating-point DCT method.
The float method is very slightly more accurate than the int method, but is
much slower unless your machine has very fast floating-point hardware. Also
note that results of the floating-point method may vary slightly across
machines, while the integer methods should give the same results everywhere.
The fast integer method is much less accurate than the other two.
The float method is mainly a legacy feature. It does not produce significantly
more accurate results than the int method, and it is much slower. The float
method may also give different results on different machines due to varying
roundoff behavior, whereas the integer methods should give the same results on
all machines.
