How to build GStreamer on Mac OS/X PPC
Goals:
- Get GStreamer to stream a video on native OS/X GUI (i.e., no XWindows). (This page, well in the future)
- Do this using the Python bindings. (GstreamerMacPython page)
- Do this in combination with wxPython. (GstreamerMacwxPython page)
- 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.
- 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
- Download, build and install liboil (http://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
- Download, build and install gst-ffmpeg from CVS:
cvs -d:pserver:anoncvs@anoncvs.freedesktop.org:/cvs/gstreamer co gst-ffmpeg
cd gst-ffmpeg

cd gst-libs/ext/ffmpeg

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