How to build GStreamer on Mac OS/X PPC

Goals:

  1. Get GStreamer to stream a video on native OS/X GUI (i.e., no XWindows). (This page, well in the future)
  1. Do this using the Python bindings. (GstreamerMacPython page)
  1. Do this in combination with wxPython. (GstreamerMacwxPython page)
  1. Use the Dirac video codec. (SchrodingerMac page)

The native OS/X audio/video plugins are in the CVS version of gst-plugins-good. Due to depedencies, this means we have to build the rest from CVS as well. I checked out on 2006/11/02. The patches may not work on other versions.

  1. Install libogg, libogg-shlibs, libvorbis0, libvorbis0-shlibs, glib2 2.12.0 and bison >= 1.35 using fink
    • I installed esound too; future will tell if it will be used
  1. Download, build and install liboil (‚Äčhttp://liboil.freedesktop.org/download/liboil-0.3.8.tar.gz)
    • To use liboil > 0.3.8, you need this patch:

Now, audio works! To test, run:

gst-launch audiotestsrc ! audioconvert ! audioresample ! osxaudiosink

  1. Download, build and install gst-ffmpeg from CVS:
    cvs -d:pserver:anoncvs@anoncvs.freedesktop.org:/cvs/gstreamer co gst-ffmpeg
    
    cd gst-ffmpeg
    
    PKG_CONFIG_PATH=/usr/local/lib/pkgconfig ./autogen.sh
    
    cd gst-libs/ext/ffmpeg
    
    ./configure --prefix=/usr/local --enable-maintainer-mode --enable-gtk-doc --disable-v4l --disable-audio-oss --disable-dv1394 --disable-vhook --disable-ffmpeg --disable-ffserver --disable-ffplay --disable-sdltest --enable-pp --cache-file=/dev/null --srcdir=. --disable-altivec
    
    cd ../../..
    
    make
    
    make install
    
    

The manual ./configure is needed to disable AltiVec, because ffmpeg refuses to compile with it enabled.
