The TRIP is the mental projection of my digital self. Including all areas of digital work I have been involved with, including Music, video, photography...
All good web pages must have the collection of absolutely useless pictures. Designed for no purpose other than to consume kilobits. And hopefully show off some of my Photographic skills. Web design skills, and uses one php script to drive the whole index. Also see the Photography section of the Silicontrip Website.
The Creative section of the TRIP is my imagination trying to run free. I have a fascination with sexual, spiritual and meta physical abilities, and these stories show it.
Part of the images directory contains some of my digital artwork. These images have been created or enhanced by myself, with the help of the 1s and 0s machine.

Still trying to work out the best way to build mjpegutils as a universal library? These are some more detailed instructions.
I would recommend against doing this as the mjpegutil configure scripts detect CPU options, such as g4/g5 optimisations and Alitvec/MMX optimisations. These optimisations must be left out for a universal build. Ideally the best way would be to build for each platform individually and then use lipo to join them together. I'll look at doing this later...
I have access to a g4, g5, core duo and core 2 duo machines I should be able to find out the ideal flags for each of these builds. However as the configure script detects cpu optimsations automatically and then generates make files for all sub projects. Finding out how to trick configure into using tunings for each Apple architecture might be difficult
Make sure universal libjpeg is built and installed, this is not optional. If you have libpng installed make sure it's universal or use the --disable-libpng configure option. And same with all other support libraries, make sure they are universal or disable them.
replace cpuinfo.sh with the following script:
#!/bin/sh echo "-arch ppc -arch i386"
configure mjpegutils. include the opposite architectures build flags Don't forget your --prefix flag if you are installing in places other than /usr/local
./configure --enable-shared --enable-static --disable-dependency-tracking --build=i386-apple-darwin
Use --build=ppc-apple-darwin for i386 machines
hack libtool, adding the LDFLAGS to the archive_cmds variable, there are two places for archive_cmds
archive_cmds="\$CC -Wl,-syslibroot /Developer/SDKs/MacOSX10.4u.sdk -arch ppc -arch i386 -dynamiclib \$allow_undefined_flag -o \$lib \$libobjs \$deplibs \$compiler_flags -install_name \$rpath/\$soname \$verstring" archive_cmds="\$CC -Wl,-syslibroot /Developer/SDKs/MacOSX10.4u.sdk -arch ppc -arch i386 -dynamiclib -single_module \$allow_undefined_flag -o \$lib \$libobjs \$deplibs \$compiler_flags -install_name \$rpath/\$soname \$verstring"
Hack config.h removing CPU specific options.
/* Inline PPC Altivec primitives available */ /* #undef HAVE_ALTIVEC */ /* Inline MMX assembly accepted by C compiler */ /* #undef HAVE_ASM_MMX */ /* Compiling for PowerPC CPU */ /* #undef HAVE_PPCCPU */ /* Compiling for x86-64 architecture CPU */ /* #undef HAVE_X86CPU */
Fortunately it appears that no code makes use of WORDS_BIGENDIAN
Now you must build each sub directory seperately
For Libraries use:
make CFLAGS="-isysroot /Developer/SDKs/MacOSX10.4u.sdk -arch ppc -arch i386" LDFLAGS="-syslibroot /Developer/SDKs/MacOSX10.4u.sdk -arch ppc -arch i386"
and Use the following for executables:
make CFLAGS="-isysroot /Developer/SDKs/MacOSX10.4u.sdk -arch ppc -arch i386" LDFLAGS="-Wl,-syslibroot /Developer/SDKs/MacOSX10.4u.sdk -arch ppc -arch i386"
mjpeg utils is made up of several packages.
utils mpeg2enc lavtools aenc mplex yuvcorrect yuvscaler yuvdenoise yuvfilters yuvdeinterlace y4mdenoise y4munsharp y4mutils
mpeg2enc is the mpeg2 encoder binary. I highly recommend building this with
optimisations as it makes heavy use of SIMD/MMX or Altivec instructions.
mpeg2enc is written in c++ and makes use of the CXXFLAGS although it
appears we can ignore this.
Build with Library make command first.
When you see the error:
unrecognized option '-syslibroot'
use the executable make command
aenc is the mpeg audio layer 2 encoder. Builds cleanly with the execute make command
mplex is the mpeg program stream multiplexer, it builds libmpeg first, so start with the library make command then switch to the executable build.
Lavtools uses libpng (I haven't yet built a universal libpng)
yuvcorrect builds an executable, use the executable make only.
yuvscaler builds an executable, use the executable make only.
yuvdenoise builds an executable, use the executable make only.
y4munsharp builds an executable, use the executable make only.
y4mutils builds several executables, use the executable make only.
You should be now ready to install.
if you see the error: /usr/bin/libtool: can't open file: 2 (No such file or directory) Means you should switch to the Library make command.
